Converter Object

Note: The Converter Object replaces the IMixer Interface.

Description

Contains the methods and properties to setup a mixer for ALL VNA Mixer/Converter applications.

Accessing the Converter Interface

Dim app as AgilentPNA835x.Application

Dim chan as Channel

Set chan = app.ActiveChannel

Dim converter as Converter

Set converter =chan.Converter

Scratch vs Applied Mixer Properties

Each mixer configuration has two sets of properties:

Scratch mixer contains the properties that have been set, but NOT YET applied. Send the Apply Method to copy these properties to the Applied mixer.
Applied mixer contains the properties that makeup the current mixer configuration.

Power settings are immediately applied to both the Scratch and Applied mixer.

A successful Calculate also performs an Apply.

Note: Queries always return the Applied mixer properties. Therefore, first send Apply Method before querying new settings.
