:MEASure:WCDMa[:CONTinuous]:RFTX:CPOWer
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:ALL
Query
This query command will start the measurement and return a result value as soon as
the measurement has been completed. The result delivered will contain the number of
segments, the starting segment and after that as many floating point numbers of of
phase (in deg) results as returned in field numer of segments.
Example
:MEAS:WCDM:RFTX:POL:PHAS?
Returns the result in a string, e.g.
34,2,3.4,3.5,3.8,...
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:CPOWer
Parameters
There are no parameters.
Description
Starts a continuous measurement of the channel power.
Query
The query form of this command will return the float value for power.
Example
:MEAS:WCDM:RFTX:CPOWer?
Starts a channel power measurement and returns the result (in dBm), e.g.
-45.3.
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:ALL
Parameters
There are no parameters.
Description
Starts a continuous measurement of the most important RF TX Modulation Quality
tests.
Query
The query form of this command starts the measurements and - after all 10 measure-
ments have been completed and all measurement results obtained - delivers a string,
containing 10 measurement result values, separated with commas. The order and
type of these measurement result values delivered back is as follows:
1. EVM RMS, floating point real number representing the RMS vector error mea-
surement in percent,
2. EVM Peak, floating point real number representing the peak vector error mea-
surement in percent,
3. Magnitude error RMS, floating point real number representing the RMS
magnitude vector error measurement in percent,
4. Magnitude error Peak, floating point real number representing the PEAK
magnitude vector error measurement in percent,
5. Phase error RMS, floating point real number representing the RMS phase
vector error measurement in degree,
6. Phase error Peak, floating point real number representing the PEAK phase
vector error measurement in degree
7. Frequency error, floating point real number representing the mobile's fre-
quency error,
8. RHO, floating point real number representing the mobile's modulation quality,
9. I/Q Offset, a floating point value with the result in dBc, representing the
result of the origin offset vector error measurement,
10. I/Q Imbalance, floating point real number representing the result of the
IQImbalance vector error measurement with the result in dB.
Note: For a further description of the single measurements, see description of the
related commands below.
