Trigger Sources
Trigger functionality is optionally to:
(1) cause one complete cycle of the selected waveform to
be output.
(2) gate the waveform output while the trigger signal is
asserted.
Software
IEEE-STD-488.2 *TRG, VXI Word
Serial trigger
Internal Internal programmable rate
generator
System Delay From External Trigger input to
Waveform Output
Standard Waveforms 120ns + 2 sample clock periods ± 1
sample clock period
Arbitrary Waveforms 150ns + 2 sample clock periods ± 1
sample clock period
External Input from:
1) Front panel BNC, TTL compatible, positive slope
2) TTLTRG0-7, Synchronous Protocol, negative slope,
VXIbus TTLTRG trigger acceptor requirements:
Minimum pulse width (logic low - asserted) : 20 ns,
Minimum pulse width (logic high - unasserted) : 20 ns,
External Output to:
TTLTRG0-7, Synchronous Protocol, negative slope,
VXIbus TTLTRG trigger source requirements:
Minimum pulse width (logic low - asserted) : 30 ns
Minimum pulse width (logic high - unasserted) : 80ns
Maximum Clock Frequency : 50 MHz
Note: For the external trigger output, the trigger source is
the programmable Synchronous Signal.
