The SPG2 Sync Pulse Generator Plug-In is a high quality sync generator designed for use in systems where accuracy, stable SCH (sync-to-subcarrier) phasing capability, and lockup mode versatility are of prime importance (Tektronix 1410 NTSC Mainframe). Two external synchronization modes, in the genlock mode, line field, and subcarrier are derived from the incoming composite video signal. The SPG2 has an output amplitude of 2 Vp-p into 75-ohms, & composite
video amplitude of 1 V into 75-ohms. It uses either internally generated or
externally supplied subcarrier for color standard reference. Subcarrier source
is front panel selectable. The SPG2 comes with two external synchronization
modes, external reference & Genlock. The input requirements for the sync
source is 1 V nominal composite video or black burst, sync negative with sync
amplitude of 286 mV 6 dB & burst amplitude of 286 mV 12 dB.
