SENSe:CORRection:SPDevice:STATe[?] OFF | ON
SENSe:CORRection:SPDevice:STATe ON
activates the s-parameter data set stored in the sensor in
order to take a component (attenuator, adapter) connected between the sensor and the DUT into
account in the measurement result. It is thus possible to calculate the power
P
fed to the DUT from the
measured value of the power sensor and the s-parameters of the attenuator or adapter.
Important
: The set of s-parameter data must be defined such that port 2 corresponds to the port on the
sensor end and port 1 to the port on the DUT end.
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. To take the influence of the DUT
into account, however, its complex reflection coefficient
DUT
at the current measurement frequency
must be transmitted to the sensor and the gamma correction must be activated (see group of
commands
SENSe:SGAMma
).
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[?] 10.0e6 to 18.0e9 (NRP-Z28), or 9.0e3 to 6.0e9 (NRP-Z98)
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]
