How to trigger DL850 with a hand-switch
The DL850 is pulled-to 5V internally; a TTL signal going-low will trigger it naturally (pulling it to LOW); likewise, it can trigger on either the rising or the falling edge of the pulse that is created by this action.
Simply fabricate a switch which will pull the BNC TRIGGER INPUT center-conductor to ground and set the TRIGGER SOURCE to 'EXTERNAL'. Then select either RISING or FALLING as trigger-edge source; the unit will not trigger on the hand-switch.
A suitable hand-switch may be:
