Safety Do not open the cover of PDG-2500. There are no user-serviceable parts inside. Opening the cover exposes you to shock and voids the factory warranty. Do not install, handle, or remove the output cables while the PDG-2500 is operating.
Controlling the PDG-2500 from the front panel 1. Disable the PDG-2500 The PDG-2500 is enabled if the Enable icon on the front panel has a checkmark. To disable, press the Disable icon or press the encoder control knob. 2. Set the frequency ...
Controlling the PDG-2500 from a computer 1. Disable the PDG-2500 Send the command “OUTPUT:DISABLE”. 2. Set the pulse trigger frequency Send the command “FREQ n”, where n = [5 to 1000000]. Units are hertz. 3. Set the pulse duty cycle Send the command “DUTYCYCLE n”, where n = [0.01 to 100.00].
5 Hz to 1.000 MHz and duty cycles of 0.00 % to 100.00 %. Single-shot pulse widths range from 80 ns to 1.0000000 second. The PDG-2500 has one analog channel with 0.000 to 5.000 V output and 16-bit adjustability.
When in computer control, pressing or turning the encoder knob returns the PDG- 2500 to front panel control. Enable Icon The Enable icon allows PDG-2500 operation. A checkmark appears when the unit is enabled. Touch Screen The touch screen provides a graphical user interface and front-panel touch control for most functions of the PDG-2500.
Power Cable Connector Accepts a 5 VDC 3 W power adapter. Power On Button Turns the PDG-2500 on. Use the touch panel “Settings” menu to turn the unit off. Accessories Included AC Power Adapter Factory-supplied 5 VDC 3 W power adapter.
Operation Power Up 1. Press the power button for 3 seconds to power up the instrument. 2. The unit plays a tune and displays the DEI information shown. 3. After a few seconds, the PDG-2500 displays the Home screen.
Set the Frequency FREQ? FREQ n 1. From the Home screen, press the Set Frequency icon. 2. The Set Frequency screen appears. 3. Press the encoder knob to change the resolution: Frequency Resolution 5 Hz to 995 Hz 5 Hz 1.0 kHz to 49.9 kHz ...
Set the Analog Output ANALOG:SETPOINT? ANALOG:SETPOINT n 1. On the Home screen, press the Analog Output icon. 2. The Set Analog Output screen appears. 3. Press the encoder knob to select a resolution: x1, x10, x100, x1,000, or x10,000. 4.
View the Communication Settings 1. On the Home screen, press the PDG-2500 icon. 2. The Settings screen appears. Press the USB Information icon. 3. The PDG-2500 USB Information screen appears. screen reports the baud rate, the number of data bits and stop bits, and the parity.
Save Settings *SAVE n 1. On the Home screen, press the PDG-2500 icon. 2. The Settings screen appears. Press the Save Settings icon. 3. The Save screen appears. Press the icon for one of the five locations to which you want to save the settings.
