:CDANalyzer:IS2000:TRACe: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 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.
If the selected location is part of a supplemental channel, all the Walsh
channels that comprise the supplemental channel and the total power
and noise value for the supplemental channel will be returned.
Syntax
MEAS:CDAN:IS2000:TRAC:POW:NOIS:ALL?
Screen/field equivalent
There are no fields on the CODE DOMAIN screen equivalent to the
return value for this query. The return information is 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 Rel on the Reference
image of the CODE DOMAIN screen.
:CDANalyzer:IS2000:TRACe:POWer:NOISe[:VALue]?
IS-2000 only. This query returns an array of 128 values that represents
the noise values relative to the selected reference channel power.
NOTE
The values returned represent the relative noise power of individual
Walsh channels not the supplemental channels of which they may be a
part. The noise levels of supplemental channels must be read directly
from the Noise Lvl value on the Code Domain Analyzer screen when
the Power & Noise measurement has been selected.
Syntax
MEAS:CDAN:IS2000:TRAC:POW:NOIS[:VAL]?
Screen/field equivalent
MEAS:CDAN:IS2000:TRAC:POW:NOIS[:VAL]? displays information
(hashed part of each bar) for the power and noise measurement when
the CD pwr unit is set to Rel on the Reference menu of the CODE
DOMAIN screen when the CDMA standard is set to “IS-2000”.
