PDG-2515/2520 Operating Manual

Figure 10 Timing Diagram

Please note that in external trigger mode, all outputs are delayed from the leading edge of the external trigger signal.

Pulse Generator Mode

In Pulse Generator Mode, the PDG-2520 generates pulses at the specified frequency denoted in the CHANNEL MENU (changing the frequency on either channel will change the frequency on both channels simultaneously – the frequencies are not independent in this mode). If externally triggered, the rate is set by the external trigger (i.e. one pulse is output each time a rising edge occurs on the TRIGGER input.

The delay of each of the outputs is relative to the leading edge of the SYNC output in internal frequency generator and single shot modes. In external trigger mode, the delay is relative to the leading edge of the external trigger input.

The pulse width and delay for each channel are independently variable.
