3 Short-Range Comms & IoT Mode
3.7 ACP Measurement
Power Ref
Selects the power reference type. This control has two different forms, depending on
the currently-selected Mode:
–
"Power Ref (Modes: SA, WCDMA, VMA, SRComms)" on page 948
–
"Power Ref (Modes: LTEAFDD, LTEATDD, 5G NR, MSR)" on page 948
Power Ref (Modes: SA, WCDMA, VMA, SRComms)
Type Option Description
Ref Carrier
RCARrier
Power of the specified carrier is the reference of measurement. Use the
Reference Carrier control to select Carrier Index
Manual Power
MANual
Power or PSD specified by the user is the reference of measurement
Total
Multicarriers
TMCarriers
Total Power of multi carriers is the power reference of measurement. Each
carrier power is calculated with its own carrier configuration settings
Remote
Command
[:SENSe]:ACPower:CARRier[1]|2:PREFerence:TYPE RCARrier | MANual | TMCarriers
[:SENSe]:ACPower:CARRier[1]|2:PREFerence:TYPE?
Subopcode: 1 = BTS/Downlink (Default), 2 = MS/Uplink
Example
:ACP:CARR:PREF:TYPE RCARrier
:ACP:CARR:PREF:TYPE?
Notes Available only in SA, WCDMA, VMA and Short-Range Comms Modes
Note that Carrier subopcode 2 is not supported in some Modes. In those cases, Carrier subopcode 1 is
used for both BTS and MS and commands with subopcode 2 are accepted without error but ignored

Type Option Description
Left & Right
Carriers
LRCarriers
Powers of leftmost and rightmost carriers with Measure Carrier On in a sub-
block are the references of left and right sides respectively. Left and right
carriers are determined based on the carrier center frequencies. If Measure
Carriers of all the carriers in a sub-block are off, the reference power in a sub-
block and all the relative power results are NaN. Relative limits are not
