Range Auto|Man
Carrier Index
Sets carrier index of the reference power. The power of the carrier selected by this
index becomes reference power when "Power Ref" on page 1560 is Carrier Index.
Remote Command
[:SENSe]:SEMask:CARRier:INDex <integer>
[:SENSe]:SEMask:CARRier:INDex?
Example
:SEM:CARR:IND 1
:SEM:CARR:IND?
Dependencies Available only in MSR, LTE-A and 5G NR Modes
Preset 1
State Saved Saved in instrument state
Min/Max MSR Mode: 1/100
LTEAFDD,LTEATDD Mode:1/5
5G NR Mode: 16
Total Power Ref
Sets the power in the carrier (ref channel) that is used to compute the relative power
values for the offsets. For modes other than MSR, LTEAFDD, LTEATDD, and 5GNR,
when "Reference Power" on page 1560 is set to Measured, this value is set to the
measured carrier reference power. When set to Manual, the result takes on the last
measured value, or can be manually entered.
For WLAN 802.11ac (80 MHz + 80 MHz), the higher of the power readouts of the
two carriers is used for computing the relative power values for the offset.
Remote
Command
[:SENSe]:SEMask:CARRier[:POWer] <real>
[:SENSe]:SEMask:CARRier[:POWer]?
Example
:SEM:CARR 100dBm
:SEM:CARR?
Notes The min and max values given are for "Measurement Type" on page 1559 = Total Pwr Ref
Couplings Coupled with Measurement Type. Active when Measurement Type is set to Total Power Ref. Otherwise,
