Triggering
Channel trigger/qualifier 1 per channel; fully independent per channel, software selectable either trigger or qualifier
Pre
-
and post
-
trigger length 0 to full memory
Maximum trigger rate 400 triggers per second
Maximum delayed trigger 1000 seconds after a trigger occurred
Manual trigger (Software) Supported
External Trigger In
Selection per card User selectable On/Off
Trigger In edge Rising/Falling mainframe selectable, identical for all cards
Minimum pulse width 500 ns
Trigger In delay
±
1 µs + maximum 1 sample period (identical for decimal and binary time base)
Send to External Trigger Out User can select to forward External Trigger In to the External Trigger Out BNC
External Trigger Out
Selection per card User selectable On/Off
Trigger Out level High/Low/Hold High; mainframe selectable, identical for all cards
Trigger Out pulse width High/Low: 12.8 µs
Hold High: Active from first mainframe trigger to end of recording
Pulse width created by mainframe; For details, please refer to the mainframe datasheet
Trigger Out delay Selectable (10 μs to 516 μs)
±
1 µs + maximum 1 sample period using decimal time base
Selectable (9.76 μs to 504 μs)
±
1 µs + maximum 1 sample period using binary time base
Default 516 (504) μs for decimal (binary) time base, compatible with standard behavior.
Minimum selectable delay is the smallest delay available for all acquisition cards used within
the mainframe
Cross channel triggering
Measurement channels Logical OR of triggers from all measured signals
Logical AND of qualifiers from all measured signals
Calculated channels
Logical OR of triggers from all calculated signals (RTC and RT
-
FDB)
Logical AND of qualifiers from all calculated signals (RTC and RT
-
FDB)
Analog channel trigger levels
Levels Maximum 2 level detectors
Resolution 16 bit (0.0015%) for each level
Direction Rising/Falling; single direction control for both levels based on selected mode
Hysteresis 0.1 to 100% of Full Scale; defines the trigger sensitivity
Analog channel trigger modes
Basic POS or NEG crossing; single level
Dual level One POS and one NEG crossing; two individual levels, logical OR
Analog channel qualifier modes
Basic Above or below level check. Enable/Disable trigger with single level
Dual (level) Outside or within bounds check. Enable/Disable trigger with dual level
Event channel trigger
Event channels Individual event trigger per event channel
Levels Trigger on rising edge or trigger on falling edge
Qualifiers Active High or Active Low for every event channel
