E–45
H
ERRor:PHASe:PEAK <max error in degrees> (query ER-
Ror:PHASe:PEAK?) — sets the maximum permitted peak phase error.
H
ERRor:PHASe:RMS <max error in degrees> (query ERRor:PHASe:RMS?)
— sets the maximum permitted RMS phase error.
H
ERRor:TTIMe <max error [S | MS | US]> (query ERRor:TTIMe?) — sets
the maximum permitted transmit time error.
H
IMBalance[:UPPer] <max imbalance [DB]> (query IMBalance[:UPPer]?) —
sets the maximum permitted imbalance between the I and Q modulation
channels.
H
WQUality[:LOWer] <min waveform quality> (query WQUality[:LOWer]?)
— sets the minimum permitted waveform quality.
The commands for configuring the base station signal levels during the tests
areas follow:
H
CONFigure:TQUality:SOURce[:CDMA]:LEVel:PILot <number [DB] |
MAXimum | MINimum> (query CONFigure:TQUality:SOURce
[:CDMA]:LEVel:PILot? [<MAXimum | MINimum>])
H
CONFigure:TQUality:SOURce[:CDMA]:LEVel:TRAFfic <number [DB] |
MAXimum | MINimum> (query CONFigure:TQUality:SOURce
[:CDMA]:LEVel:TRAFfic? [<MAXimum | MINimum>])
H
CONFigure:TQUality:SOURce[:CDMA]:POWer <number [DBM] |
MAXimum | MINimum> (query CONFigure:TQUality:SOURce
[:CDMA]:POWer? <MAXimum | MINimum>)
Refer to the descriptions of the command with similar keywords under the
heading Base Station Configuration on page E–14 for discussion of the settings
affected by these commands.
Analog.
There are four different transmitter quality tests, each of which has
different mnemonics in the command language.
H
Hum/Noise
The hum/noise test is started and the results are returned with the query:
READ[:SCALar]:ATQuality:HNOise[:ALL]?. The values returned are (in
order) the relative level of hum/noise in dB and the audio peak deviation
in Hz.
The pass/fail indications of the hum/noise test can be obtained with the
query: FETCh[:SCALar]:ATQuality:HNOise:LIMit:FAIL[:ALL]?. This
query returns (in order) 0 (pass) or 1 (fail) indicators for the relative level of
hum/noise and the audio peak deviation.
