SENSe:CORRection:OFFSet[?] –200.0 to 200.0
SENSe:CORRection:OFFSet defines a fixed offset in dB, which is used to correct the measured value.
(When a log scale is used, the offset is added to the measured value; this is the reason why the
command has this name.)
The attenuation of an attenuator located ahead of the sensor or the coupling attenuation of a directional
coupler is taken into account with a positive offset, i.e. the sensor calculates the power at the input of
the attenuator or directional coupler. A negative offset can be used to correct the influence of a gain
connected ahead.
The query yields the set offset in dB.
Default setting: 0.0 [dB]
SENSe:CORRection:OFFSet:STATe[?] OFF | ON
SENSe:CORRection:OFFSet:STATe ON activates the offset correction and SENSe:CORRection
:OFFSet:STATe OFF deactivates it.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
SENSe:CORRection:SPDevice:STATe[?] OFF | ON
SENSe:CORRection:SPDevice:STATe ON activates the s-parameter data set for a component
(attenuator, directional coupler) connected ahead of the sensor. Parameter OFF deactivates it.
The use of s-parameters instead of a fixed offset (see group of commands SENSe:CORRection
:OFFSet) allows more precise measurements, since the interactions between the sensor, the source
and components connected between them can be taken into account. (For detailed information on
loading s-parameter data sets, refer to section 3.) The sensor has no factory-set s-parameter data set.
In this state, the SENSe:CORRection:SPDevice:STATe ON command generates an error message.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting:
The factory-set default setting of the sensor is OFF. On loading an s-parameter table, the default setting
can be redefined (see section 3).
SENSe:FREQuency[?] 9.0e3 to 6.0e9
SENSe:FREQuency transfers the carrier frequency of the RF signal to be measured; this frequency is
used for the frequency-response correction of the measurement result. The center frequency is set for
broadband signals (spread-spectrum signals, multicarrier signals).
The query yields the set carrier frequency in Hz.
Default setting: 50.0e6 [Hz]
