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.
