KSU
Fast Preset External Mixer
The KSU command presets the external mixer mode by setting the frequency range to 18.0-26.5 GHz. This
frequency range is derived from the 6th harmonic of the analyzer local oscillator. The functions of the KSU
command and the front panel m U4 keys are identical.
'When KSU is executed, the analyzer does a fast preset (similar to KST) and readies the analyzer for external
mixing by locking the frequency range to the 6th harmonic. The current harmonic number is displayed above the
graticule, and the current conversion loss is displayed to the left of the graticule.
If a harmonic lock (such as KSt) is in effect, an "I." is also displayed following the current harmonic number.
Changing the frequency range with start and stop frequencies automatically changes the local oscillator frequency
to the corresponding harmonic.
