:CDANalyzer:IS2000:TRACe:ABSolute:POWer:NOISe: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 a flag indicating that the next bar 
should be connected to this bar as part of a wider supplemental 
channel.
Syntax
MEAS:CDAN:IS2000:TRAC:ABS:POW:NOIS: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:NOISe[:VALue]?
IS-2000 only. This query returns an array of 128 values representing 
each channel’s true (absolute) noise power.
NOTE
The values returned represent the absolute noise power of individual 
Walsh channels not the noise of supplemental channels of which they 
may be a part. The noise of supplemental channels must be read 
directly from the 
Noise Lvl
 value on the CODE DOMAIN screen with 
the Power & Noise measurement activated, or using the query 
MEAS:CDAN:IS2000:TRAC:ABS:POW:POW:ALL?
Syntax
MEAS:CDAN:IS2000:TRAC:POW:NOIS[:VAL]?
Screen/field equivalent
MEAS:CDAN:IS2000:TRAC:ABS:POW:NOIS[:VAL]? returns the noise 
portion (hatched 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”.
