± 1 µs + maximum 1 sample period (for decimal and binary time base)
Delay
User can select to forward External Trigger In to the External Trigger Out BNC
Selection per card
User selectable On/Off
Active level
High / Low / Hold High; selectable per mainframe, identical for all cards
Pulse width
High / Low: 12.8 µs
Hold high: Active from first mainframe trigger to end of recording
Pulse width created by mainframe
516 µs ± 1 µs + maximum 1 sample period using decimal time base
Delay
504 µs ± 1 µs + maximum 1 sample period using binary time base
Channels on card
Logical OR; Analog triggers of all channels
Logical AND; Qualifiers of all channels
Cards in mainframe
User selectable through system trigger bus
Selections: Send/Receive/Transceive (Send & Receive)
Connections
3 System trigger busses connecting all cards within mainframe
1 Master/Slave bus connecting all cards within mainframe and connecting all mainframes
when using Master/Slave option
Operation
Logical OR of all triggers of all cards
Logical AND of all qualifiers of all cards
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
Pulse detect/reject
Disable/Detect/Reject selectable. Maximum pulse width 65 535 samples
dY/dT conversion
dY : 16 bit (0.0015 %) for both levels
dT : 1 to 1023 samples. dT setting shared for both levels
Basic
POS or NEG crossing; single level
Dual level
One POS and one NEG crossing; Two individual levels, OR-ed
Window
Arm/trigger and a disarm level; Trigger on peak-level changes in a uni-polar signal
Dual Window
Arm/trigger/disarm per level; Trigger on peak-level changes in a bi-polar signal
Sequential
One arm and one trigger level; eliminate false triggering due to noise or hysteresis
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
Disable channel trigger for 1 to 65 535 samples after trigger detected
Maximum holdoff time sample rate dependent
Modes
Less then, trigger when rate is too low
More then, trigger when rate is too high
Between, trigger when rate between lower and upper limit
Not between, trigger when rate is not between lower and upper limit
Interval timers
Start timer and width Timer
Timer value
1 to 65 535 samples
