CALibration<[1]..4>:DATA
<data>
Read and write binary calibration data sets for the selected sensor.
Parameters:
<data>
block_data
CALibration<[1]..4>:ZERO:AUTO
<auto>
CALibration:ALL:ZERO:AUTO
<state>
Performs zeroing using the signal at the sensor input(s). The sensor(s) must be discon-
nected from all power sources.
Error messages:
-231
"Data questionable; ZERO ERROR"
: Signal at the input considerably deviates from 0 W.
-224
"Illegal parameter value"
: The transfer parameter is a numeric value unequal 0 (corresponds
to OFF).
The setting commands accept only the parameters
ONCE
,
LFR
and
UFR
, they start of
zeroing;
OFF
and
ON
are ignored.
The queries return the value
ON
if a calibration is in progress, otherwise value
OFF
.
The parameters
LFR
(lower frequency range) and
UFR
(upper frequency range) limit
zeroing to a lower and an upper frequency range, thus reducing the required time by half.
These parameters are not accepted by all sensors. Before using them, you should consult
the manual of the sensor concerned.
Another possibility to perform zeroing faster is to use the command
CALibration<[1]..4>:ZERO:FAST:AUTO
in the trace mode.
The commands are overlapping, i.e. other commands can be sent to the R&S
NRP2 while
one or more calibrations are running.
Zeroing is recommended if
●
the temperature has varied by more than about 5
°C,
●
the sensor has been replaced,
●
no zeroing was performed in the last 24 hours,
●
signals of very low power are to be measured, for instance, if the expected measured
value is less than 10 dB above the lower measurement range limit.
Parameters:
<state>
ON | OFF | ONCE | LFR | UFR
