CALibration Subsystem NRT
1080.9506.02 3.22 E-6
3.5.7 CALibration Subsystem
The CALibration subsystem contains the command for zeroing and all commands for frequency re-
sponse correction of NAP power sensors.

<n> = 0 to 3 (sensor port) <m> = 1 to 3 (calibration data set)
:CALibration<n>:ZERO
This command causes zeroing to be carried out for the sensor connected to port <n> (suffix <n>,
see Section 3.5.1). No RF power shall be applied to the sensor during zeroing.
Example: :
CAL2:ZERO
No *RST value
Zeroing must be completed before a new measurement can be started. The command *WAI allows
to recognize the end of a zeroing procedure. An error status request allows to check whether the ze-
roing procedure was performed successfully:
CALL IBWRT(sensor%,
"
CAL<n>:ZERO;*WAI
"
)
test% = 1
WHILE test% = 1
CALL IBWRT(sensor%,
"
SYST:ERR?
"
)
CALL IBRD(sensor%, ErrText$)
IF LEFT$(ErrText$, 1) =
"
0
"
THEN test% = 0
IF LEFT$(ErrText$, 4) =
"
-200
"
THEN PRINT
"
no zeroing
"
END
:CALibration0
This node provides all commands for selecting and editing the calibration data sets for NAP power
sensors. The commands are only available in conjunction with Option NRT-B1 (<n> = 0). The suffix
<m> designates one of the three calibration data sets in the NRT (<m> = 1, 2, 3 for SET1, SET2 or
SET3).
