The "Z-Blanking" output on the back of the HP3336 works when it goes low --
just have to match the scan time for both units and we are off to the races.
Thanks for the input.

Trigger or reference ?

Says:
External trigger input: negative going TTL level or contact closure
required to initiate sweep
External reference input: 10 MHz (or subharmonic to 1 MHz), 0 dBm
minimum level
