PDG-2515/2520 Operating Manual

X10 button once to increment it to 250ns, then rotate the encoder wheel to increase it to 300ns. At this point, pressing the X10 button again would increase the delay to 3.00us, pressing it again increments it to 30.0us, etc.

An additional function is that if it is held while changing ANY frequency value, after multiplying the value by a factor of ten, if the encoder is moved it will increase/decrease at a much faster rate. This makes the switching frequency much quicker and easier.

PW/PRF Button

This is for varying the parameters Frequency and Pulse Width and toggling between the two settings quickly. If you are in any menu that is not a CHANNEL MENU, it will flip you immediately to the CHANNEL 1 menu and the FREQUENCY setting.

Out 1 and Out 2

These are the pulse output connectors. The outputs of the PDG-2515 should be connected to the inputs of the receiving instrument or system using 50 Ohm coaxial cable. For optimal pulse fidelity, these outputs should be terminated into 50 Ohms.

Sync Out

This is a 5V signal into 1 meg-Ohm or 2.5V signal into 50 Ohms that is synchronous with the frequency generator trigger. This is designed to assist the user in triggering when monitoring the output signals with an oscilloscope, or for use in triggering an external instrument.

Trigger In

This is an input signal into 1KOhms used for external Pulse Repetition Frequency (PRF) triggering. It is designed to allow the user to trigger multiple PDG-2515 units from a single pulse generator. This allows the user to create synchronous waveforms from multiple units.

Power LED

Indicates that the power switch on the rear of the unit is in the ‘on’ position and that AC power is applied to the unit.

Front Panel Controls & Connections

AC Power Entry Module

The driver is grounded through the grounding conductor of the AC power cord. To avoid electrical shock, plug the driver into a properly wired receptacle before making connection to any input or output connectors. Use only a power cord that is in good condition.
