Dual Channel Tracking

Background

As only the AFG-225 has dual channels, it has a
number of tracking functions not available on the
AFG-125. The tracking functions are listed below.

Dual Channel
Functions

Function

Description

Frequency Coupling

Frequency coupling will
couple the channel outputs by
frequency. Frequency
coupling can be achieved by
frequency offset or by a
frequency ratio.

Amplitude Coupling

Amplitude coupling will
couple the both channel
outputs by amplitude. Any
changes in amplitude in one
channel is reflected in the
other channel.

Tracking

There are two tracking modes,
ON and Inverted. When
turned on, tracking performs
frequency and amplitude
tracking so the channels
behave as a single channel.
When set to inverted, the one
channel will output the
inverse of the other.

S_Phase

S_Phase will synchronize the
phase of both channels.

Steps

1. From the first level AFG menu,

press UTIL and then press Dual
Chan
on the side menu.
