Name Description
DataStreamChBSpectrum: DevDouble
DataStreamChASpectrum: DevDouble
FilePrefixScalar: DevString
FileDirScalar: DevString
LiveModeScalar: DevBoolean If 1 acquisition will run continuously
ATDNbTriggerDelaySamplesScalar: DevLong The number of samples to wait before collecting data, after the trigger arrives
ATDPreTriggerSamplesScalar: DevLong The number of samples to collect from before the trigger point
ATDNbRepitedAccuScalar: DevLong Number of times to repeat the accumulation, creating a new record. A value of 4294967295 (0xFFFFFFFF) indicates infinite repeats.
ATDNbAccumulationsScalar: DevLong Number of accumulations to perform. [1, 65536] supported with safe scaling
ATDRecordLengthScalar: DevLong Length of record in samples. Multiple of 72 required
WFAFlagsScalar: DevLong A bit mask that specifies different behaviours
WFANbTriggerDelaySamplesScalar: DevLong The number of samples to hold off after the trigger event
WFAPreTriggerSamplesScalar: DevLong The number of pretrigger samples for each waveform
WFANbSamplesScalar: DevLong The number of samples per waveform
WFANbWaveformsScalar: DevLong The number of waveforms to average
MultiRecordPreTriggerSamplesScalar: DevLong The number of pre-trigger samples. Must be less than the MultiRecord record size. Granularity ADQ214: 2 samples.
ExtTrigEdgeScalar: DevLong Specifies which edge to use: 0: Falling edge 1: Rising edge 2: Both edges (ADQ12 / ADQ14 only)
LvlTrigResetValueScalar: DevLong64 The offset from the trigger level for which the level trigger shall arm the trigger for detecting rising or falling edges. Read the last set value.
LvlTrigLevelScalar: DevLong Trigger level in codes
LvlTrigEdgeScalar: DevLong Trigger edge
LvlTrigChannelScalar: DevLong A mask that tells the ADQ which channels that are active • channels = 0 => None • channels = 1 => Channel A • channels = 2 => Channel B • channels = 4 => Channel C • channels = 8 => Channel D To trig on multiple channels add the channel code for each individual channel. Examples: • channels = 10 => Any of Channel B and D • channels = 15 => Any Channel Values given for any non-existing channel is simply ignored
InputRangeChBScalar: DevDouble
InputRangeChAScalar: DevDouble
TriggerModeScalar: DevLong 1 -> software 2 -> external 3 -> level 4 -> internal
ClockSourceScalar: DevLong 0 -> int_intref 1 -> int_extref 2 -> ext
RecordsCollectedScalar: DevLong Records collected in current/last acquisition
NbSamplesPerRecordScalar: DevLong Number os samples per record to acquire
NbRecordsScalar: DevLong Number of records to acquire.
TemperatureScalar: DevDouble
AcqModeScalar: DevLong Acquisition mode: 0 -> multirecord, 1 -> wfa, 2 -> atd


Name Description
StopAcquisitionInput: DevVoid
Output: DevVoid
StartAcquisitionInput: DevVoid
Output: DevVoid
Start acquisition in the mode selected by AcqMode
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.



Name Description
