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[?] 0.0e6 to (sensor-dependent upper limit)
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]
