Dual Channel Operations
Dual Channel Operations
This section covers most topics related to dual channel operation. It does not cover the optional IQ Player.
Entering Dual Channel Operation
You enter dual channel configuration by pressing a channel output button, then More, then Dual Channel.
Frequency Coupling
Frequency coupling allows you to couple frequencies or sample rates between channels, either by a constant ratio or off-
set between them. Press Freq Cpl to turn frequency coupling on or off, and press Freq Cpl Settings to configure
frequency coupling.
The Freq Cpl Settings softkey opens the menu shown below. The first softkey allows you to specify whether you
want to couple the frequencies with a ratio or an offset, and the second softkey allows you to specify the ratio or offset.
Amplitude Coupling
Amplitude coupling, enabled by the Ampl Cpl softkey, couples the amplitude and offset voltage between the channels
so that changing the amplitude or offset on one channel affects both channels.
Tracking
Tracking, configured by the Tracking softkey, has three modes: Off, On and Invert. When tracking is off, the two
channels operate independently. When tracking is on, they behave as one channel. The third mode, Invert, makes
the channels' outputs inverses of each other, resulting in a differential channel using both outputs.
