Agilent Technologies 5988-7401EN Pulses

Using the Agilent 81133A/81134A Pulse Generator Timing of Generated Signals

78 Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005

Pulses

The following figure shows the typical timing for contin uous pulses.

Characteristics • Puls e periods can be either generated continuously or can be

started manually or by the a rming source.

• Delay, pulse width (or duty cycle) and deskew can be set for each

channel.

• The instrument mode is Pulse/Pattern.

• The pattern mode is Pulse.

• For the clock source, you can select from:

–Internal (YIG Oscillator)

–External signal at Clock Input

–External 10 MHz Reference at Clock Input

For more information about the clock sources, see “Clock Sources”

on page 73.

• The Trigger Out is generated with every clock pu lse, but can be

optionally divided by any number in the range 1 ... 231 – 1.
