PDG-2515/2520 Operating Manual

Product Overview

Description

The PDG-2515 is a two 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 operates in continuous mode, channel 2

 

pulses every Nth pulse on channel 1.

Burst Mode

Generates a burst of pulses, repeating at a

 

frequency.

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.
