PulseGenerator Object

Description

Contains the properties for configuring the five internal pulse generators in the PNA-X.

Learn more about the PNA-X Pulse Generators.

Accessing the PulseGenerator object

Dim app as AgilentPNA835x.Application
Dim chan as Channel
Set chan = app.ActiveChannel
Dim pulse as PulseGenerator
Set pulse = chan.PulseGenerator

Each pulse generator is specified in the Pulse Generator properties.

External Pulse Generators

Beginning with A.09.50, External Pulse Generators can be used with the Integrated Pulse Application.

Use chan.PulseGeneratorNames and chan.PulseGeneratorID to refer to the external pulse generator when setting properties on this (PulseGenerator) Object.

 

Pulse Definitions

  • D = Delay; the time before each pulse begins

  • W = Width; the time the pulse is ON

  • P = Period; one complete pulse cycle

  • W/P = Duty Cycle; the ratio of pulse ON/OFF

Important: If D + W is greater than P, then undefined VNA behavior results. There is NO error message or warning.
