Example
:HARM:FREQ:FUND 1 GHZ
:HARM:FREQ:FUND?
Notes Forces measurement restart
Dependencies Sense is not available for VXT
Couplings Affected by "Freq Offset" on page 1908
Preset The frequency found when initiating an Auto Tune from the current measurement condition
Min 1 Hz
Max Half the maximum available instrument frequency
Auto Function
Remote
Command
[:SENSe]:HARMonics:FREQuency:FUNDamental:AUTO OFF | ON | 0 | 1
[:SENSe]:HARMonics:FREQuency:FUNDamental:AUTO?
Preset
ON
Freq Step
Lets you change the step size for the fundamental frequency. Once a step size has
been selected and the fundamental frequency function is active, the step keys (and
the UP|DOWN parameters for Fundamental Frequency from remote commands)
change frequency by the step-size value.
Remote
Command
[:SENSe]:HARMonics:FREQuency:STEP[:INCRement] <freq>
[:SENSe]:HARMonics:FREQuency:STEP[:INCRement]?
Example
:HARM:FREQ:STEP 1 MHZ
:HARM:FREQ:STEP?
Preset 1 GHz
Min 1 Hz
Max Set by the instrument maximum frequency
Freq Offset
Enables you to set a frequency offset value to account for frequency conversions
outside of the instrument. This value is added to the display readout of the marker
frequency, center frequency, start frequency, stop frequency, and all other absolute
frequency settings in the instrument including frequency count. When a frequency
offset is entered, the value appears below the center of the graticule. To eliminate
an offset, perform a Mode Preset or set the frequency offset to 0Hz.
Remote Command
[:SENSe]:FREQuency:OFFSet <freq>
