for the following models: · A1110-05-E (Rev. B) · A1110-16-E (Rev. B) · A1110-16-E-100 (Rev. B) · A1110-40-E-70-32 (Rev. B) 1.2 Device Description The A1110-40-E is a linear, extreme-broadband, precision power amplifier designed for all applications which require fast-changing signals with high performance. The A1110-40-E can be operated as a voltage amplifier or current amplifier. The current amplifier offers a constant, frequency-invariant output current for inductive loads. Three optional operating voltages per polarity are available for high-voltage/low-current or lowvoltage/high-current applications. The voltage switch-over can be implemented optionally as manual. Especially in case of very low-impedance loads, the operating voltage can be reduced to 1/3 which is associated with a corresponding reduction of the power loss.Output voltage and output current can be limited and observed on low-impedance monitor outputs. The device is equipped with a temperature-controlled, quietly-running fan. As well as an overtemperature protection, a power-loss calculation and an absolute-current monitoring guarantees perfect short-circuit and overload protection. An interlock offers the possibility of a remote-controlled security system. The device can be operated by using elements on the front panel. Additionally the device can be controlled with the supplied A1110 Control Software via an USB or Ethernet connection. The functionality of the device can be further extended with various product options. You can find more information on this at www.drhubert.de on the respective product pages. Always read the enclosed data sheet The separate data sheet is part of these operating instructions and must also be read and understood. Device-specific modifications on customer request can only be found in the data sheet!

Manual A1110 E-Series Page 8 3 Important Information for Initial Operation 3.1 Introduction It is imperative that the following operating instructions for the 4-quadrant power amplifier and the connected peripherals are read before installation and commissioning. Further information can be found in ,,White Paper No. 1" on our website www.drhubert.com. It is also imperative that the following operating instructions for the 4-quadrant power amplifier and the connected peripherals are read before installation and initial startup. Furthermore, the configuration and initial startup of the amplifier with the connected load must be carried out by appropriately trained and qualified personnel. Monitoring of output current and output voltage The monitor outputs of the fast 4-quadrant power amplifier should always be used to monitor the voltage and current at the DUT in order to detect unwanted RF oscillations or other instabilities (extensive overshoots) at an early stage. 3.2 Connecting the Power Outputs Do not connect the 4-quadrant power amplifier output to any other amplifier, external power supply, signal source or other active, inappropriate loads. These special electrical components are not excluded as a load in principle but it requires a suitable security concept. Application Support In the implementation of your application, our technical support is happy to help! Overvoltage at the Power Output The amplifier has no protection against overvoltage at the power output! Example: In the case of an inductive load, switching off the amplifier can lead to high voltages at the outputs and possibly to the destruction of the 4-quadrant power amplifier. Take the appropriate safety measures (see option "Overvoltage Protection"). Do not connect the outputs to the signal ground or the protective earth! Multiple earthing can lead to unstable operation or interfere with current monitoring. Manual A1110 E-Series Page 9 3.3 Parallel Operation (Voltage Amplifier) By connecting several 4-quadrant power amplifiers in parallel, the output current can be increased. For safe operation it is absolutely necessary to · only use identical amplifier models · observe the wiring instructions and cable specifications for stable signal processing (e.g. equal cable length) · ensure adequate mains supply · ensure contact protection at the power outputs, life-threatening voltages can occur For the operating mode "current amplifier" please contact our technical support. Parallel operation with an external active load or source is not permitted! 3.4 Series Operation (Voltage Amplifier) By connecting several 4-quadrant power amplifiers in series, the output voltage can be increased. For safe operation it is absolutely necessary to · only use identical amplifier models · observe the wiring instructions and cable specifications for stable signal processing · ensure adequate mains supply · ensure contact protection at the power outputs, life-threatening voltages can occur For the operating mode "current amplifier" please contact our technical support. Series operation with an external active load or source is not permitted! For the operating mode "current amplifier" please contact our technical support. Manual A1110 E-Series Page 10 3.5 Series Operation of DC- and 4-Quadrant Power Amplifier In a series connection of a DC source and a 4-quadrant power amplifier, systems with different transmission characteristics (e.g. slew rate) and operating voltages are often used. Communication between the systems is also not always guaranteed. Figure 1: DC- and AC-Source (4-Quadrant Power Amplifier) in Series Operation In the event of an error (for example the over-current protection of the power amplifier triggers, i.e. the output becomes high-impedance), this can lead to voltages at the amplifier output that are (permanently) above its supply voltage. Permanently if the DC source does not turn off. Overvoltage at the Power Output The amplifier has no protection against overvoltage at the power output! Overvoltage Protection The device option "Overvoltage Protection" offers convenient overvoltage protection.

Manual A1110 E-Series Page 15 5 Notes on Operation 5.1 General Information Make sure there is enough space behind and in front of the amplifier to allow air to circulate freely through the unit. Cool air is sucked in through the slots on the left and right sides of the front panel. Do not connect the amplifier to the power outlet until input and output are wired. Allow the amplifier to warm up for 15 minutes after power-up to stabilize its operating points. 5.2 Operating Voltages (A1110-05/16-E and A1110-05/16-E-100) Check your product model This chapter applies only to the models mentioned. Read the appropriate chapter for your product to prevent damage to the device. Before you start "amplifying", we recommend that you consider the choice of operating voltage for effective and safe operation of the A1110-40-QE (see also White Paper No.1: Hubert Power Amplifier). The amplifiers of the E series have three operating voltages: · high operating voltage (±90 V*) for high output voltages and low load currents · medium operating voltage (±60 V) for medium output voltages and medium load currents. · low operating voltage (±30 V) for low output voltages and high load currents (* The high operating voltage of the A1110-05/16-E-100 is ±110 V.) To keep the power loss of the amplifier low, the operating voltage should always be selected according to the load. Example: The load current IL should be 5 ADC. Load 1: RL = 10 For IL = 5 ADC, an output voltage Ua = 50 Vdc is required (Ua = IL * RL). The power loss PV at the output stage results from the voltage drop at the output stage multiplied by the current through the output stage: PV = (UB - Ua) * IL = ( 90 V - 50 VDC) * 5 ADC = 200 W Load 2: RL = 1 An output voltage Ua = 5 VDC is required for the same load current IL = 5 ADC. The power loss at high operating voltage is therefore PV = (UB - Ua) * IL = ( 90 V - 5 VDC) * 5 ADC = 425 W If you now switch to the operating voltage Ulow, the following picture emerges: PV = (UB - Ua) * IL = ( 30 V - 5 VDC) * 5 ADC = 125 W Manual A1110 E-Series Page 16 As you can see from this example, it makes more sense to operate the amplifier with a low operating voltage for low-impedance loads and with a high operating voltage for highimpedance loads. An illustration with the maximum output voltages and output currents (U-I plot) can be found in the data sheet Operating voltages (A1110-40-E-70-16 and A1110-40-E-70-32) Check the exact model name! This chapter only applies to the specified model. Read the chapter that applies to your product to prevent damage to the appliance. The A1110-40-E-70-16 and A1110-40-E-70-32 models are optimized for applications that primarily require positive output voltages, such as test systems for automotive standards. In principle, the same considerations apply here as in chapter 3. The operating voltage should always be selected according to the load: · High operating voltage for high output voltages and low output currents · Low operating voltage for low output voltages and high output currents The A1110-40-E-70-16 and A1110-40-E-70-32 have three positive and one negative operating voltage, which can be selected manually. For further information, please refer to the data sheet. 5.3 Connecting the load The A1110-E series has a balanced signal input (balanced input) which offers advantages for long signal paths (see also White Paper No.4: Balanced Input). If your signal source does not have a balanced output, the signal can also be transmitted unbalanced using a BNC/XLR adapter (included accessory). Always use high-quality shielded cables with low capacitance (<60 pF/m) for cabling. 5.4 Initial Operation in Operating Mode Voltage Amplifier Connect the mains cable and switch on the mains voltage at the mains switch. The illuminated power button signals standby and you can switch the device on. After a short time, ready lights up and the amplifier is now ready for operation. Start the software and establish a data connection with the amplifier. Select the Voltage Mode operating mode and the required operating voltage according to your application. Use Amplifier On to switch on the signal input and the power output and signal processing can begin. Do not switch off the mains supply under load! The corresponding signal forms can be controlled at the Voltage Monitor Out and Current Monitor Out outputs. Manual A1110 E-Series Page 17 5.5 Initial Operation in Operating Mode Current Amplifier In the "current control" operating mode, the A1110-E behaves like a voltage-controlled current source and supplies an almost frequency-independent constant load current to an inductive load. Figures 5 and 6 show examples of the transients of the output voltage and current in the "current control" and "voltage control" operating modes on an inductor. With this device the current mode is blocked ex works! If you need to activate it, please contact our support team and ask for specific advice regarding your project.

Since the load represents an integral part of the control in the "current control" mode, the amplifiermust be compensated for stability reasons with an RC network adapted to the load. The following instructions for safe operation of the A1110-40-QE must also be observed: 1. Never put the amplifier into operation without load. 2. A DC current path must always be existing through the load. Never employ capacitors in the signal path. 3. Wire up the amplifier completely before operational startup. 4. Pay attention to correct compensation. 5. Monitor the output current for stability. 6. Do not change the operating mode during operation. Manual A1110 E-Series Page 18 Figure 9: Simplified Current Controller The figure above shows the RC network required for the current controller. If no customer-specific solution was required, the following networks are equipped ex works: No Load 1 1 Ohm + 500 µH 2 0,1 Ohm + 200 µH 3 1 Ohm + 1mH 4 4 Ohm + 1,8 mH 5 Reserved for Option-01 6 Reserved for Option-01 Rc 100 k 68 k 150 k 200 k Cc 10 nF 4,7 nF 22 nF 1 nF Current Range high high high high Table 1: Compensation networks The selection is made by software. Please also note the corresponding recommended current measuring range. Network No 7 allows the determination of a suitable compensation by means of a switchable capacitor bank and a variable resistor. After you have wired the amplifier and connected it to the load, you can enable the mains voltage at the mains switch. The illuminated power button signals standby and you can switch on the unit. After a short time, the Ready LED is lit and the amplifier is now ready for operation. Start the software for further settings and retrieving its status. Now establish a data connection to the amplifier. Select the required operating voltage and the required compensation network according to your application. · Activate the Current Mode. This connects the amplifier output to the load the control loop is closed. · Switch on the signal input and the power output by selecting Amplifier On. The signal processing can begin. At the outputs Voltage Monitor Out and Current Monitor Out, the corresponding signal forms can be checked. Manual A1110 E-Series Page 19 Leaving the Current Mode follows in reverse order: · Switch off the external signal source · Switch off the signal input with Amplifier Off · Disable the Current Mode. The loade can now be removed from the amplifier output Never remove the load from the amplifier output in Current Mode! Manual A1110 E-Series Page 20 5.6 Sensing Voltage drops occur via supply lines, which ensure that the entire voltage is not measured at the load. With the sensing option, the output voltage of the amplifier is regulated to such an extent that the desired voltage is present at the load. The internal voltage drop is thus compensated. The option can be controlled via our "HUBERT A1110 Control" software or via a command set. Figure 10: Exemplary test setup with sensing option used In the standard case, sensing is deactivated (0 mV). Without active sensing, a lower voltage drops across the load (RL) due to the supply line resistance (RZ). If sensing is activated to 500 mV, 1000 mV or 2000 mV via the application software, the amplifier compensates for the voltage drop via the lead resistance. This means that the voltage at the load corresponds to the input voltage multiplied by the gain factor of the amplifier (x10). The voltage value set for sensing indicates the maximum readjusted voltage. Manual A1110 E-Series Page 21 5.7 Adjustable Output Resistance This extension complements our A1110 series power amplifiers with a programmable internal resistance. This option allows the amplifier output resistance, which is a few milliohms, to be compensated to zero. Depending on the requirements, the internal resistance of the power amplifier can be set from 0 m to 200m with a resolution of 1m. The option is optimized for DC voltage operation. This option is used for electrical testing of electrical and electronic components in motor vehicles in accordance with the LV124 or VW80000, VW80300, etc. standards. The option can be controlled via our "HUBERT A1110 Control" software or via a command set. Figure 11: internal resistance vs. frequency When using the "Adjustable output resistance", you must have selected the Voltage mode and it must not be used at the same time as the Sensing option. Manual A1110 E-Series Page 22 Figure 12: Power amplifier with adjustable output resistance Amplifier output resistance: Rv 17 m (different for each amplifier / see data sheet) Adjustable output resistance: Ri = 0...200 m (variable) Switching the output resistors: [1] Option deactivated, [2] Option activated Load: RL = 1 Input Signal: Us = 1 VDC · IDLE In this operating mode, no load is connected to the output terminals, so no output current flows (I = 0 ADC). For Us = 1 VDC, Uq = 10 VDC (amplification factor = 10) is obtained. As there is no voltage drop across Ur (Ur = Rv * I = 17 m * 0 ADC = 0 VDC or Ur = Ri * I = 100 m * 0 ADC = 0 VDC), the voltage is present at the output terminals (Uq = Uout). · WITH LOAD (OPTION DEACTIVATED [1] ) Now we connect a load to the output of the amplifier and obtain the current I = Uq / (Rv + RL) = 10 VDC / ( 17 m + 1 ) = 9,83 ADC. This means that a voltage of Ur = Rv * I = 17 m * 9,83 ADC = 0,17 VDC drops across the amplifier output resistor. The output voltage at the amplifier is now Uout = Uq - Ur = 10 VDC 0,17 VDC = 9,83 VDC. · WITH LOAD (OPTION ACTIVATED [2] RI = 0 ) Now we activate the option and set an output resistance of Ri = 0m and receive the electricity I = Uq / (Ri + RL) = 10 VDC / ( 0 m + 1 ) = 10 ADC. This means that a voltage of Ur = Ri * I = 0 m * 10 ADC = 0 VDC drops across the adjustable output resistor. The output voltage at the amplifier is now Uout = Uq - Ur = 10 VDC 0 VDC = 10 VDC. · WITH LOAD (OPTION ACTIVATED [2] RI = 0,1 ) Manual A1110 E-Series Page 23 If you change the output resistance to 100 m, you get the current I = Uq / (Ri + RL) = 10 VDC / ( 100 m + 1 ) = 9,09 ADC. This means that a voltage of Ur = Ri * I = 100 m * 9,09 ADC = 0,91 VDC drops across the adjustable output resistor. The output voltage at the amplifier is now Uout = Uq - Ur = 10 VDC 0,91 VDC = 9,09 VDC. 6 Applications Please find more information in sections ,,White Papers" and ,,FAQs" on our website www.drhubert.com.

Please refer to the software user manual for further operating instructions. You can always find the latest version at www.drhubert.de Manual A1110 E-Series Page 25 8 Integration into Automated Test Systems The command set for integrating the A1110-E into automated test systems is described below. A command frame is defined as follows: <length of the frame> <command word> <opt. parameter> The commands described in this section are ASCII/hex values that are transmitted as hex numbers using a terminal program (e.g. HTerm, 9600 baud, 8 bits, one stop bit, no parity). These do not correspond to the SCPI standard and are defined as a pure byte protocol. The amplifier sends either the command or parameters as confirmation for a received and executed command frame (see table below). The settings for the behavior in the event of power loss shutdown and restart are saved in the device. For example, the amplifier can be configured so that it switches on again automatically after a configurable time (10-254 s) in the event of a power loss switch-off. 8.1 List of commands Command Frame (Tx) <0x02><0x04> <0x02><0x05> <0x02><0x06> <0x02><0x0E> <0x02><0x10> Return (Rx) <1 Byte> <0x05> <0x06> <1 Byte> <1 Byte> <0x03><0x20> <Parameter> <1 Byte> <0x03><0x21> <Parameter> <0x02><0x22> <0x02><0x23> <0x02><0x25> <1 Byte> <1 Byte> <1 Byte> <2 Bytes> Note and parameter description Send the temperatur in °C Setting the high operating voltage Setting the low operating voltage Sending the power loss in % (0xFA = 100%) Sending the device status: Bit 0: Ready Bit 1: Overload Bit 2: Overtemperature Bit 3: Don´t care Bit 4: Interlock aktiv Bit 5/6: Supply voltage 1-1 = ps high 0-1 = ps mid 0-0 = ps low Bit 7: Device on/off Setting the switch-on configuration of the amplifier: Bit 0: Restart after Overload-Shutdown 0: deaktiviert 1: aktiviert Bit 1: don´t care Bit 2/3: supply voltage 1-1 = ps high 0-1 = ps mid 0-0 = ps low Bit 4 bis 7: must remain 0 Setting the switch-on delay time after an overload switch-off in seconds (0x0A bis 0xFE).
