4.1.2 Freq Offset
Set the frequency offset value to illustrate the frequency conversion between the measured device
and the input of the spectrum analyzer.
⚫ This parameter does not affect any hardware settings of the spectrum analyzer, but only
changes the display values of center frequency, start frequency and stop frequency.
⚫ To eliminate the frequency offset value, the frequency offset value can be set to 0 Hz.
Command Format [:SENSe]:FREQuency:OFFSet
[:SENSe]:FREQuency:OFFSet?
Instruction Sets the frequency offset of the spectrum analyzer.
Gets the frequency offset.
Parameter Type Float, unit: Hz, kHz, MHz, GHz
Parameter Range
-
100 GHz ~ 100 GHz
Return Float, unit: Hz
Example :FREQuency:OFFSet 1 GHz
4.1.3 Freq Step
Setting the value of Freq Step will change the direction key step of center frequency, start
frequency, stop frequency and frequency offset.
⚫ At a fixed step change the value of the center frequency can reach the purpose of switching
measurement channels rapidly and continuously.
⚫ There are two kinds of frequency step modes ： Auto and Manual . In Auto mode, the Freq step
is 1/10 of the span in Non-zero span or equals the RBW while in Zero Span. In Manual mode,
you can set the step using the numeric keys.
Command Format [:SENSe]:FREQuency:CENTer:STEP[:INCRement]
[:SENSe]:FREQuency:CENTer:STEP[:INCRement]?
Instruction Specifies the center frequency step size.
Gets the center frequency step.
Parameter Type Float, unit: Hz, kHz, MHz, GHz
Parameter Range 1 Hz ~ 40 MHz
Return Float, unit: Hz
Example :FREQuency:CENTer:STEP 2 MHz
