DESCRIPTION

WAVEFORM_SETUP, WFSU
Command/Query
The WAVEFORM_SETUP command specifies the amount of
data in a waveform which will be transmitted to the controller. The
command controls the settings of the following parameters:
a. Sparsing (SP). The sparsing parameter defines the interval
(0..25000) between data points. For example:
SP = 0 reads all data points
SP = 1 reads all data points
SP
= 4 reads every 4th data point
b. Number of points (NP). The number of points parameter
indicates how many points should be transmitted. For ex-
ample:
NP = 0 sends all data points
NP = 1 sends 1 data point
NP = 5 sends a maximum of 5 data points
NP = 10 sends a maximum of 10 data points
c. First point (FP). The first point parameter specifies the
address of the first data point to be sent. For waveforms
acquired in sequence mode, this refers to the relative ad-
dress in the given segment. For example:
FP = 0 corresponds to the first data point
FP = 1 corresponds to the second data point
FP = 5000 corresponds to data point 5001
d. Segment number (SN). The segment number parameter
indicates which segment should be sent if the waveform
was acquired in sequence mode. This parameter is ignored
for non-segmented waveforms. For example:
SN = 0 all segments
SN = 1 first segment
SN = 23 segment 23
The WAVEFORM_SETUP? query returns the transfer parame-
ters currently in use.
