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.
Do not use this device in a manner not specified by the manufacturer.
Do not use where liquids are present or in corrosive environments. Clean this
instrument by wiping with a dry or damp cloth.
Use ONLY NiMH (nickel-metal hydride) batteries.
Quick Start Guide
Safety
Follow the safety guidelines on previous page. DO NOT PROCEED WITHOUT
UNDERSTANDING AND OBSERVING THESE GUIDELINES.
Requirements
Make sure the PDG-2500 is:
connected with the proper cables and termination impedance
powered up
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
Press the Frequency icon on the touch screen.
Press the encoder knob to set the resolution.
Turn the encoder knob to set the frequency.
Press the Done icon.
3. Set the duty cycle
Press the Duty Cycle icon on the touch screen.
Press the encoder knob to set the resolution.
Turn the encoder knob to set the duty cycle.
Press the Done icon.
4. Enable the PDG-2500
Press the Enable icon on the touch screen. The icon displays a checkmark.
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].
Units are percent.
4. Set the analog voltage
Send the command “ANALOG:SETPOINT n”, where n = [0 to 65536].
Units are DAC counts of 5 V/65535 = 76.293 µV each.
5. Enable the PDG-2500
Send the command “OUTPUT:ENABLE”.
Introduction
Description
The PDG-2500 is a single-channel pulse generator source for laser drivers or other
devices requiring a precise frequency generator. It provides pulse repetition
frequencies from 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.
The frequency, duty cycle, and analog amplitude are adjustable from the touch
screen or by computer control via USB interface. The digital output requires a 50 Ω
termination.
Using the instrument is extremely simple using the color LCD touch-screen and a
control knob. The PDG-2500 has the ability to store five unique user settings.
The PDG-2500 is a hand-held system and is battery powered for portability and
electrical isolation.
Typical Uses for the PDG-2500
Panel Layout
All features of the front touch screen and the top end panel are labeled. Their
functions are covered in the next sections.
Front Panel Features
Local Mode
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
