RIGGERING

(TTL

RIGGER

)

The SMP7500 is capable of generating VXI TTL triggers. The generated TTL triggers may be
used to signal another VXI instrument that a SMP7500 event has occurred. To generate the trigger
output, the SMP7500 can select a front panel connector clock line or any Relay Register Write
Event for use in generating the trigger signal.
