Set External Mixer LO Harmonic Value
[ :SENSe] :MIXer :HARMonic <value >
[ :SENSe] :MIXer :HARMonic ?
This command allows you to set the LO harmonic value for mixers
other than the HP/Agilent 11970-Series or 11974-Series Mixers . This i s
done after the mixer harmonic configuration
([ : SENSe] :Mixer : HARMonic :AUTO <boolean>) is set to manual .
This command is available only on model E4407B analyzers having
Option AYZ.

Range : Any non-zero integer from -50 to 50, inclusiv e
Remarks: The harmonic value with its associated sign i s
automatically determined from the external mixe r
band selected . This is the AUTO mode . For mixers
other than the HP/Agilent 11970-Series o r
11974-Series, an LO harmonic other than that
determined in the AUTO mode may be required . This i s
achieved using this command and related comman d
