Item Description/Default Range of Values
character_data – HRESolution: high resolution. The complete capture buffer at the internal
sample rate. The number of points in this trace is not fixed, as it is affected by the
SENS:TRACe:TIMe setting.
– MRESolution: medium resolution. A subset of the capture buffer - the buffer
contents are decimated
to 1000 data points.
– LRESolution: low resolution. A subset of the capture buffer - the buffer
contents are decimated to provide 230 data points. This is the same number of
data points as the power meter uses to display the trace on the front panel. Hence,
the LRES command can be used to replicate the power meter’s display.
