PDG-2515/2520 Operating Manual

Product Overview

Description

The PDG-2520 is a four channel digital delay/pulse generator. Each channel offers independently adjustable delay and width, with 25 nanosecond resolution. Up to five user configurations may be stored in internal non-volatile memory, and recalled through the easy to understand front panel.

Functions & Features

Delay And Width and Each channel provides independently adjustable

Duty Cycle.delay and width, with 25ns resolution. The duty cycle is limited based on the frequency. The duty cycle is limited approximately by the equation:

	MAX DC = 97-[(1E-5)*FREQ].
Frequency	Pulse repetition frequency from single shot to
	continuous pulses from 100 mHz to 3.0 MHz.
Resolution	100mHZ to 1.0 MHz -> 3 digits
	1.0 MHz + -> 2 digits
Trigger Sources	Internal, External, Single Shot.
Pulse Generator	Generates pulses at the rate set by the internal
Mode	frequency generator, or by an external trigger.
Pulse Count Mode	Outputs pulses at the rate set by the internal
	frequency generator or external trigger and stops
	after N pulses.
Divide By N Mode	Channel 1 and Channel 3 operates in continuous
	mode. Channel 2 and Channel 4 pulses every Nth
	pulse.
Burst Mode	Generates a burst of pulses, repeating at a
	frequency on Channel 1.
Counted Burst Mode	Generates a burst of pulses, and stops after N
	bursts.
Store And Recall	Stores up to 5 user configurations in non-volatile
	memory.
