2.4.2 Output Power Adjusting Screw
The output power of the converter can not be adjusted via the network analyzer. When
the frequency converter mode is activated at the network analyzer, the output power of
the analyzer is set to a fixed value optimized for the selected type of frequency converter.
The screw at the top of the converter allows to adjust the output power of the waveguide
test port. Turning the screw clockwise reduces the output power while turning the screw
counter-clockwise increases the output power. Adjusting the screw to 0 mm results in
minimum power while maximum power is reached at about 2 mm. If you accidentally
unscrew the knob completely, simply screw it on again. If you readjust the screw after
calibration, the power calibration is still valid but the system error correction has to be
repeated.

The rear panel of the frequency converter provides the connectors and control elements
shown in the following figure.
