5. Setup
5.1 Power Connection
Connect the provided DC 5V power adapter to the power input port on the rear panel of the JDS6600 unit. Plug the adapter into a suitable power outlet.
5.2 USB Connection (for PC Control)
To control the JDS6600 via PC software, connect the unit to your computer using the supplied USB cable. The USB port is located on the rear panel.
5.3 Output Connections
Connect BNC cables to the CH1 and CH2 output terminals on the front panel. These cables can then be connected to an oscilloscope, frequency counter, or other test equipment.
5.4 Software Installation
The JDS6600 comes with PC software that allows for comprehensive control and arbitrary waveform generation. Install the software from the provided CD or download the latest version from the manufacturer's website. Follow the on-screen instructions for driver and software installation.
6. Operating Instructions
6.1 Basic Operation
After connecting the power, press the power button to turn on the device. The display will show the default settings for CH1 and CH2. Use the CH1 and CH2 buttons to toggle the output of each channel on or off. The rotary encoder is used to navigate menus and adjust parameter values.
6.2 Waveform Selection and Parameter Adjustment
Press the WAVE button to cycle through available waveform types. Once a waveform is selected, use the dedicated function buttons (FREQ, AMPL, OFFS, DUTY, PHAS) to adjust its parameters. Turn the rotary encoder to change the values, and press OK to confirm.
6.3 System Settings
Press the SYS button to access system settings. Here you can save and load configurations, adjust sound and brightness, change the display language, and manage other system-wide preferences.
6.4 Modulation Modes
Press the MOD button to enter modulation mode. You can select various modulation types such as Sweep Frequency, Pulse Generator, and Burst. Use the arrow keys and rotary encoder to configure the modulation parameters.
6.5 Measurement Mode
The MEAS button allows you to use the device as a frequency counter for external signals. Connect the external signal to the 'Ext. IN' BNC port and configure the measurement settings via the menu.
6.6 PC Software Control
Once the PC software is installed and the device is connected via USB, you can control all functions from your computer. The software interface mirrors the device's controls, allowing for precise adjustments and the creation of custom arbitrary waveforms. This enables advanced signal generation and analysis.
7. Maintenance
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid using abrasive cleaners or solvents that could damage the casing or display.
- Store the device in a cool, dry environment when not in use.
- Regularly check cables and connectors for any signs of wear or damage.
8. Troubleshooting
- No Power: Check the power adapter connection and ensure the power outlet is functional.
- No Signal Output: Verify that the correct channel (CH1 or CH2) is enabled and that parameters like amplitude and frequency are set appropriately. Check cable connections.
- PC Software Connection Issues: Ensure USB drivers are correctly installed (refer to Section 5.4). Check the COM port selection in the software.
- Incorrect Waveform Display: Confirm that the selected waveform type and parameters match your intended output.
