Reference Process Variables
The following table lists the PVs for the reference channel settings used to configure the
waveform storage channels. These PVs are duplicated for each reference channel. In
the following table,
N
is substituted with the appropriate channel number from 1 to 4 (for
example: Ref1Enable).

Store
mbbo Discrete
Store a waveform from the selected channel to the
reference channel. Source channels:
“INP1” = input channel 1
“INP2” = input channel 2
“INP3” = input channel 3 (ZT4xx2)
“INP4” = input channel 4 (ZT4xx2)
“CALC1” = calculate channel 1
“CALC2” = calculate channel 2
“CALC3” = calculate channel 3
“CALC4” = calculate channel 4
“REF1” = reference channel 1
“REF2” = reference channel 2
“REF3” = reference channel 3
“REF4” = reference channel 4
