10 REMOTE SYNC INPUT Pin 10 can be used to input Remote Sync or
90 Hz (100 Hz PAL) Sync. Remote Sync is
usually a field-rate square wave. It is routed
around the Sync Stripper and directly to the
Sweep Gating circuitry.
90 (100) HZ INPUT 90 HZ Sync input signal is a TTL level square
wave
11 STORE Low = Store disabled. When this line is low,
the front-panel STORE button is disabled.

15 FRONT–PANEL PRESET 3
This function allows the 1730-Series to be triggered by a 2 V, 90 Hz (NTSC) or
100 Hz (PAL) square-wave output from a D-2 VTR. The display is a single field
rate sweep selected when the front-panel SWEEP is set to 2FLD. 90 Hz (100
Hz) sweep triggering disables the 1730-Series Remote Sync Input.
The 90 Hz (100 Hz) sweep trigger, when enabled, is input through pin 10 of the
rear–panel REMOTE connector. To enable this option (and disable Remote
Sync) reposition two internal jumpers:
