PSD Ref (Modes: SA, WCDMA, VMA, SRComms)
This is used when "Power Ref" on page 1056 is Manual and "Measurement Type" on
page 1055 is PSD.
Sets the power spectral density in the carrier (main channel) that is used to compute
the relative power spectral density values for the offsets when Measurement Type is
PSD Ref.
Remote Command
[:SENSe]:ACPower:CARRier[1]|2:CPSD <real>
[:SENSe]:ACPower:CARRier[1]|2:CPSD?
Subopcode: 1 = BTS/Downlink (Default), 2 = MS/Uplink
Example
:ACP:CARR:CPSD 25
:ACP:CARR:CPSD?
Notes Although the default value is defined, the value is recalculated by the measurement result just after
measurement
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
Dependencies Available only when Measurement Type is PSDRef, otherwise grayed-out
Couplings The value of PSD Ref is automatically converted when PSD Unit is changed
Preset 0.0
State Saved Saved in instrument state
Min/Max -999/999
Power Ref State (Backwards Compatibility SCPI)
Sets the Power Reference State to auto or manual.
Example
:ACP:CARR:AUTO OFF
:ACP:CARR:AUTO?
:MCP:CARR:AUTO ON
:MCP:CARR:AUTO?
Notes For backwards compatibility with legacy SA and WCDMA, this command is supported
When ON, corresponds to the Ref Carrier of the "Power Ref" on page 1056 selection
When OFF, corresponds to the Manual of the Power Ref selection
