module of a multi-instrument. m runs from 0 to (nbr of
modules –1).
"ASBus_ m_SerialNb"
ViInt32
Serial number of the m'th module of a multi-instrument. m
runs from 0 to (nbr of modules –1).
"ASBus_ m_SlotNb"
ViInt32
Slot number of the m'th module of a multi-instrument. m
runs from 0 to (nbr of modules –1).
"CrateNb"
ViInt32 Physical crate number (perhaps from AqGeo.map)
"DelayOffset"
ViReal64 Calibrated Delay Offset
(only useful for recovery of battery backed-up acquisitions)
"DelayScale"
ViReal64 Calibrated Delay Scale
(only useful for recovery of battery backed-up acquisitions)
"ExtCkRatio"
ViReal64 Ratio of sFmax over external clock inputFrequency
"HasTrigVeto"
ViInt32 Returns 1 if the functionality is available, 0 otherwise.
