Chapter 8 — WCDMA Commands 8-10 :READ Subsystem
MS2720T PM PN: 10580-00341 Rev. C 8-37
8-10 :READ Subsystem
This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any
current triggering sequence and sets the trigger state to idle. It then initiates a new active
measurement (i.e. begins the collection of new data). When the measurement is complete, it
returns the result. These commands will not switch to another measurement.
To get the current measurement data, use the FETCh command.
:READ:ACLR?
Title: Read Adjacent Channel Leakage Ratio (ACLR)
Description: Triggers a new adjacent channel power ratio measurement and returns
the results: main channel power, lower adjacent and upper adjacent
channel power, and lower alternate and upper alternate channel power.
It is a combination of the commands :ABORT, :INITiate, and
:FETCh:ACLR? The ACLR measurement must be the active
measurement (specified by :CONFigure:RF ACLR). The current
measurement can be queried using :CONFigure?
Data is returned as 12 comma-separated values: –20 MHz channel
power, –15 MHz channel power, –10 MHz channel power, –5 MHz
channel power, Main channel power 1, Main channel power 2, Main
channel power 3, Main channel power 4, +5 MHz channel power,
+10 MHz channel power, +15 MHz channel power, +20 MHz channel
power.
Related Command: :CONFigure:RF ACLR
:READ:CHPower?
Title: Read Channel Power
Description: Triggers a new channel power measurement and returns the channel
power result. It is a combination of the commands :ABORT, :INITiate,
and :FETCh:CHPower:CHPower? It returns only the channel power,
not the channel power density. Use the command :READ:CHPower? to
get both channel power and channel power density. The channel power
measurement must be the active measurement (specified by
:CONFigure:CHPower). The current measurement can be queried using
the :CONFigure? command.
Default Unit: Current amplitude units
