Product-Specific Commands—Description
The <Data> response corresponds to the Y-axis
values vector of the trace. Returned values are
evenly spaced relative to the X-axis expressed in
meter.
X-axis wavelength interval between each Y value
is determined as follow:
interval = (stop - start) / (count - 1) where:
start = TRACe[:DATA]:X:STARt[:WAVelength]?
stop = TRACe[:DATA]:X:STOP[:WAVelength]?
count = TRACe:POINts?
The points unit is determined by the trace
definition context. When trace data represents
absolute power, returned values are in dBm.
When trace data represents relative power,
returned values are in dB.
Example(s) <Do measurement>

01,...
FORMat:DATA PACK
TRAC:DATA? "TRC1" Returns binary data
:TRACe[:DATA][:Y][:WAVElength]?
