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
1
to 1000
data points.
• LRESolution: low resolution. A subset of the capture
buffer - the buffer contents are decimated
1
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.
