: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”.
