: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”.
