4.4.2 Harmonic Sweep
Harmonic sweep offsets the frequency of the signal generator from the frequency of the PSA. One
application for harmonic sweep is amplifier test. See the following graphic.
Mode: Spectrum Analysis
Key Path:
Source, Config Sweep
Remote Command: :SOURce:EXTernal:SWEep:HARMonic <real>
:SOURce:EXTernal:SWEep:HARMonic?
:SOURce:EXTernal:SWEep:HARMonic:STATe ON|OFF|1|0
:SOURce:EXTernal:SWEep:HARMonic:STATe?
Factory Preset: 1, OFF
State Saved: Saved in instrument state.
Dependencies and
Couplings:
Parameter is disabled if active mode is not Spectrum Analyzer
or a connection has not been established at the specified IP
address.
The harmonic range is restricted by both the frequency range of
the spectrum analyzer and the frequency range of the external
source.
If the calculated external source start or stop frequency exceeds
the frequency range of the external source Error Message 13227
will be reported and the sweep stopped until you adjust either
analyzer start or stop frequency, the frequency offset (if ON) or
harmonic (if ON) such that the frequency range can be swept by
the signal source and analyzer simultaneously. Once the
frequency range of the external source is valid the error is
cleared and the sweep resumes.
Example: SOUR:EXT:SWE:HARM 2
