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
Duty Cycle. Each channel provides independently adjustable
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
Resolution
Pulse repetition frequency from single shot to
continuous pulses from 100 mHz to 3.0 MHz.
100mHZ to 1.0 MHz -> 3 digits
1.0 MHz + -> 2 digits
Trigger Sources Internal, External, Single Shot.
Pulse Generator
Mode Generates pulses at the rate set by the internal
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.
