 The upper radio buttons loop a module into the signal path.
 The lower radio buttons cause the modules to be bypassed.
 Pulse Generators... opens a dialog to configure the pulse generator signals controlling the pulse
modulators.
The Extension Unit provides three signal paths:
 Source path for port 3
The source signal from the analyzer is fed to the SOURCE PORT 3 IN connector of the Extension
Unit. The modified source signal is looped back to the analyzer so that it is available at the test
port. The internal R&S ZVAX signal path (green rectangle in the figure below) may contain the
following modules:
 A harmonic filter for very accurate frequency-converting measurements, in particular
harmonics measurements
 A pulse modulator to generate a pulsed source signal
 An external amplifier connected to the PORT 3 SOURCE IN / OUT connectors on the rear
panel of the Extension Unit. The amplifier boosts the source signal after the pulse
modulator stage
 A combiner for the two source signals from the analyzer ports no. 1 and 3. After
connecting the SOURCE IN / OUT connectors of both ports, the combined source signal
is available at analyzer port no. 1.
All modules are optional. The "empty" source path is a simple through connection between the
SOURCE PORT 3 IN and SOURCE PORT 3 OUT connectors of the Extension Unit.
