CALC#:POW
Syntax:
CALCulate<channel 1 to 2>[:CHANnel]:POWer
space<
sensor 1 or 2>
Example:
OUTPUT @PWR_MTR;CALC2:POW 1
! CONFIGURES CHANNEL 2 TO
! MEASURES SENSOR 1 POWER
Description:
This command configures a sensor to an individual channel, and the channel measures the
sensor power level. This command does not have a query format. For the example above, the
response to a CALC2? query is POW 1. This command should be executed only after the
designated sensor has been calibrated.
CALC#:RAT
Syntax:
CALCulate<channel 1 to 2>[:CHANnel]:RATio
space
<sensor 1 or 2
comma
sensor 2 or 1>
Example:
OUTPUT @PWR_MTR;CALC1:RAT 2,1
! CONFIGURES CHANNEL 1 TO MEASURE
! SENSOR 2 OVER SENSOR 1 POWER
Description:
This command configures a channel as a ratio of the power levels present at the two sensors.
When UNITs are dBm, RATio configuration produces measurements in dB. When UNITS are
Watts, RATio configuration measurements are percentage. This command does not have a
query format. For the above example, the response to a CALC1? query is RAT 2,1. This
command should be executed only after the designated sensor has been calibrated.
CALC#:DIFF
Syntax:
CALCulate<channel 1 to 2>[:CHANnel]:DIFFerence
space
<sensor 1 or 2
comma
sensor 2 or 1>
Example:
OUTPUT @PWR_MTR;INIT:CONT ON
! CONFIGURES CHANNEL 1 TO MEASURE
! SENSOR 2 MINUS SENSOR 1 POWER
Description:
This command configures a channel as the difference between the power levels present at
the two sensors. UNITs are dBm or Watts. This command does not have a query format. For
the above example, the response to a CALC1? query is DIFF 2,1. This command should be
executed only after the designated sensor has been calibrated.
CALC#?
Syntax:
CALCulate<channel 1 to 2>[:FUNCtion]?
Example:
OUTPUT @PWR_MTR;CALC2?
! QUERIES CHANNEL 2 SENSOR CONFIGURATION
Response:
POW #, RAT #,#, OR DIFF #,#
Description:
This command returns the current channel configuration. This command is a query format
only.
