4.2 Interfaces

The instrument includes several interfaces for connectivity and data transfer:

• USB Host: For connecting USB storage devices to save/load waveforms and settings.
• USB Device: For connecting to a computer for remote control and data transfer.
• LAN: For network connectivity and remote control.
• Digital Output: A multi-pin connector for 16 channels of digital output.

5. Setup

Follow these steps to set up your HDG2062B function generator:

1. Power Connection: Connect the provided power cord to the AC inlet on the rear panel of the instrument and then to a grounded power outlet.
2. Power On: Press the power button located on the front panel to turn on the instrument. The display will illuminate, and the system will boot up.
3. Initial Check: After booting, the instrument will display the default waveform settings. Ensure the display is clear and responsive.
4. Connect Outputs: Connect BNC cables from the CH1 or CH2 output ports to your desired load or measurement device (e.g., oscilloscope, circuit).

6. Operating Instructions

6.1 Basic Waveform Generation

To generate a standard waveform:

1. Press the Wave button to select the desired waveform type (e.g., Sine, Square, Ramp, Pulse, Noise).
2. Use the numeric keypad or the rotary knob to set the Frequency. Press the corresponding soft key on the display to confirm or change units.
3. Adjust the Amplitude (peak-to-peak voltage) using the dedicated soft key and rotary knob/keypad.
4. Set the Offset (DC offset) if required.
5. Press the Output On/Off button for the selected channel (CH1 or CH2) to enable the waveform output.

6.2 Arbitrary Waveform Generation

The HDG2062B supports arbitrary waveform generation with 64M memory depth and 16-bit resolution.

• Creating Arbitrary Waveforms: Waveforms can be created using the included PC software, imported from a USB drive, or defined point-by-point on the instrument.
• Loading Arbitrary Waveforms: Navigate to the 'Arb' menu, select 'Load', and choose your desired waveform from internal memory or a connected USB device.
• Outputting Arbitrary Waveforms: Once loaded, set the frequency, amplitude, and offset as with standard waveforms, then enable the output.

6.3 Modulation Functions

The instrument supports various modulation types:

• Press the Mod button to access modulation settings.
• Select the desired modulation type: AM (Amplitude Modulation), FM (Frequency Modulation), PM (Phase Modulation), ASK (Amplitude Shift Keying), FSK (Frequency Shift Keying), PSK (Phase Shift Keying), or PWM (Pulse Width Modulation).
• Configure the modulation parameters (e.g., modulation depth, frequency deviation, carrier frequency) using the soft keys and rotary knob/keypad.
• Enable the modulation.

6.4 Digital Output

The HDG2062B features 16 channels of digital output, allowing for the generation of mixed signals.

• Connect a suitable cable to the digital output connector.
• Access the digital output settings through the menu.
• Configure the pattern and timing for each of the 16 digital channels.

6.5 Frequency Counter

The built-in 80MHz frequency counter can measure external signals.

• Connect the external signal to the dedicated counter input (if available, or through a general-purpose input).
• Select the 'Counter' function from the utility menu.
• The display will show the measured frequency of the input signal.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your instrument:

• Cleaning: Use a soft, dry cloth to clean the exterior of the instrument. For stubborn dirt, a slightly damp cloth with mild detergent can be used. Avoid abrasive cleaners or solvents.
• Storage: When not in use, store the instrument in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Calibration: Periodic calibration by qualified service personnel is recommended to maintain measurement accuracy.

8. Troubleshooting

If you encounter issues, refer to the following common troubleshooting steps:

• No Power: Ensure the power cord is securely connected to both the instrument and a working power outlet. Check the power button.
• No Output Signal: Verify that the output for the selected channel (CH1/CH2) is enabled. Check cable connections to the load. Ensure amplitude and frequency settings are valid.
• Incorrect Waveform: Confirm the correct waveform type is selected. Check frequency, amplitude, and offset settings.
• Display Issues: If the display is blank or distorted, try restarting the instrument. If the problem persists, contact technical support.
