3. Setup Instructions

Follow these steps to properly set up your JDS8060 Function Arbitrary Waveform Generator.

Figure 3.1: Rear panel of the JDS8060 Function Generator, showing power input, output, and control ports.

1. Power Connection: Connect the provided AC power cord to the power input socket on the rear panel (refer to Figure 3.1). Ensure the power switch is in the OFF position before connecting. The device supports AC 85-264V, 47-63Hz.
2. Output Connections: Connect your test leads or cables to the 'OUT' (Channel 1) and 'SYNC' (Channel 2) BNC connectors on the rear panel for waveform output. The 'IN' BNC connector is for external trigger or modulation input.
3. TTL.Ext Port: For external TTL signal input/output, use the TTL.Ext port. Refer to the pinout diagram on the rear panel for correct connections (Pins 1, 3, 5, 7, 9 for GP1, GP01, GP02, GP03, GP04 respectively; Pins 2, 4, 6, 8, 10 for +5V, +5V, GND, GND, GND respectively).
4. USB Connection: For PC connectivity and software control, connect a USB cable to the USB port.
5. DC5V Input: An auxiliary DC5V input is available for specific applications.
6. Power On: Once all connections are secure, switch the power button to the ON position. The device will initiate its startup sequence.

4. Operating Instructions

This section provides general guidance on operating the JDS8060. For detailed operation of specific functions, refer to the on-screen menu and dedicated function buttons.

4.1 Basic Waveform Generation

1. Select Channel: Use the channel selection buttons (CH1/CH2) to choose the desired output channel.
2. Select Waveform Type: Navigate through the menu to select the desired waveform (e.g., Sine, Square, Triangle, Arbitrary).
3. Set Frequency: Adjust the frequency using the dedicated frequency controls or numeric keypad. The sine wave frequency range is 1nHz-60MHz.
4. Set Amplitude: Adjust the peak-to-peak amplitude (Vpp) for the selected channel. The amplitude range varies with frequency.
5. Set Offset: Adjust the DC offset voltage if required.
6. Enable Output: Ensure the output for the selected channel is enabled to generate the waveform.

4.2 Advanced Functions

• Modulation: Access the modulation menu to configure AM, FM, PM, ASK, FSK, or PSK modulation. Select the modulation source and parameters.
• Sweep Function: Utilize the sweep function to vary frequency, amplitude, or duty cycle over a specified range and time. Choose between linear and logarithmic sweep modes.
• Arbitrary Waveform: Create and load custom arbitrary waveforms using the device's interface or PC software. The waveform length is 8192 points per channel.
• Frequency Measurement: The built-in frequency meter can measure external signals. Connect the signal to the appropriate input and select the measurement function.
• VCO Function: The Voltage Controlled Oscillator (VCO) function allows external voltage control of frequency, amplitude, and duty cycle.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your JDS8060 Function Arbitrary Waveform Generator.

• Cleaning: Regularly clean the exterior of the device with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with mild detergent, ensuring no liquid enters the device. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure that the ventilation slots on the device are not obstructed to prevent overheating. Operate the device in a well-ventilated area.
• Storage: When not in use for extended periods, store the device in a cool, dry place, away from direct sunlight, dust, and extreme temperatures.
• Cable Inspection: Periodically inspect all cables (power, BNC, USB) for any signs of damage or wear. Replace damaged cables immediately.
• Fuse Replacement: The device uses a 250Vac, T3.15A fuse. If the device does not power on, check and replace the fuse located near the AC power input if necessary. Ensure the device is disconnected from power before attempting fuse replacement.

6. Troubleshooting

This section addresses common issues you might encounter with your JDS8060.

• Device does not power on:
  • Check if the power cord is securely connected to both the device and the power outlet.
  • Verify that the power outlet is functional.
  • Inspect the power fuse on the rear panel and replace if blown (refer to Maintenance section).
• No output signal:
  • Ensure the output for the selected channel is enabled in the device's menu.
  • Check the BNC cables connecting the device to your measurement equipment (e.g., oscilloscope) for proper connection and integrity.
  • Verify that the amplitude setting is not set to 0Vpp.
  • Confirm that the frequency is within the supported range for the selected waveform.
• Incorrect waveform displayed:
  • Check the waveform type selection in the device's menu.
