:CDANalyzer:IS2000:TRACe:ABSolute:POWer:POWer:ALL?
IS-2000 only. This query returns the information necessary to recreate
the Code Domain trace when making a Power and Noise measurement.
The return entity consists of 128 four value records for each bar in the
trace. The four values for each record are channel number, Power for
this channel, Noise for this channel, and a flag indicating that the next
bar should be connected to this bar as part of a wider supplemental
channel.
When the selected location is part of a supplemental channel, all the
Walsh channels that comprise the supplemental channel will be
returned. If it is part of a supplemental channel, the total power for the
supplemental channel will be returned.
Syntax
MEAS:CDAN:IS2000:TRAC:ABS:POW:POW:ALL?
Screen/field equivalent
There are no fields on the CODE DOMAIN screen equivalent to the
return values for these queries. These values are only accessible when
the CDMA standard is set to “IS-2000”, the measurement selected is
Power and Noise, and CD pwr unit is set to Abs on the Reference
image of the CODE DOMAIN screen.
:CDANalyzer:IS2000:TRACe:ABSolute:POWer:POWer[:VALue]?
IS-2000 only. This query returns an array of 128 values representing
the true (absolute) power for each channel’s power level when making a
Power & Noise measurement.
NOTE
The value returned represents the absolute power of individual Walsh
channels not the supplemental channel of which they may be a part.
The power of supplemental channels must be read directly from the
Marker Lvl value on the CODE DOMAIN screen with the Power &
Noise measurement selected.
Syntax
MEAS:CDAN:IS2000:TRAC:ABS:POW:POW[:VAL]?
Screen/field equivalent
MEAS:CDAN:IS2000:TRAC:ABS:POW:POW[:VAL]? returns the power
portion (top bars on the screen) of the measured power of each channel
of a Power and Noise measurement, when CD pwr unit is set to Abs on
the Reference image of the CODE DOMAIN screen when the CDMA
standard is set to “IS-2000”.
