Acquisition Process Variables
The following table lists the PVs for the waveform acquisition settings. These PVs
configure the common acquisition settings of all input channels.
Process Variable Type
Values
Description
setAcqType
getAcqType
mbbo
mbbi
Discrete
Waveform acquisition type:
“NORM” = normal
“AVER” = average
“ENV” = envelope
“PDET” = peak detect
“HRES” = high resolution
“FAST” = fast acquisition
“ETIM” = equivalent-time
setAcqCount
getAcqCount
longout
longin
2 to 65536 in
powers of 2
Waveform count for multiple-capture acquisition
types of average, envelope, equivalent-time, and
fast acquisition
setEnvView
getEnvView
mbbo
mbbi
Discrete
Envelope view select:
“MIN” = minimum
“MAX” = maximum
setAverView
getAverView
mbbo
mbbi
Discrete
Average view select:
“AVER” = average
“SEGM” = segments
SegCount longin
variable,
>=0
Queries
the number of historical segments
captured. This is only valid for History mode.
setSegView
getSegView
longin
longout
0 to SegCount Sets or queries the current segment view. This is
only valid for History mode. The viewed segment
is the segment returned in waveform downloads
and the segment used for measurements and
calculations.
setSegMode
getSegMode
mbbo
mbbi
Discrete
Segment mode select:
“HIST” = history mode
“ZOOM” = zoom mode
