Requirements
Remote Sync
Amplitude 2.0 to 5.0 V square wave, or
4.0 V composite sync.
Input enabled through
rear-panel REMOTE con-
nector.
Input Impedance
1 MW.
Frequency 30/60 Hz (NTSC), 25/50 Hz
(PAL) square wave will
synchronize a 2-field
sweep. Remote sync by-
passes the sync stripper
and field ID circuits.
