Some installations use 525/59.94 and 625/50 component signals simultaneously or switch between standards regularly. Dual-standard operation is possible with the SPG 422 architecture. Also important for dual-standard operation, is the ability of the SPG 422 to output audio tones locked to the video standard(s) in use. 1–1...

Specifications The SPG 422 has a front-panel interface that controls all instrument functions. Also, the user can control the SPG 422 via either a parallel ground-closure remote or RS-232. The ground-closure remote provides simple control of a few major instrument functions, while the RS-232 implementation is a SCPI (Standard Commands for Programmable Instruments) command language interface, with most of the front-panel interface capabilities.

Analog Black reference signal either with or without burst. If burst is not present, then the SPG 422 can lock to the sync (instead of burst lock). Configure the genlock as either a loopthrough or two terminated inputs.
Page 64: Genlock Input Configuration
Figure 2–2A shows the genlock as a loopthrough signal from genlock A to genlock B. This application is common when the SPG 422 is close to the master sync generator and the master sync still has other equipment to feed.
Page 65: Black Signals
There are at least two analog black outputs available from the rear panel. (If the SPG 422 is Option 1, then there are six analog black outputs.) Configure each separately for standard, timing, and signal type. If the selected standard is different from the genlock input, then it locks to the internal oscillator that is “clock-locked”...

Option 1 Board The SPG 422 Option 1 board contains four identical, separate dual-standard black generators. Each generator runs on a 27 MHz master clock, with PAL and NTSC frame resets to synchronize them and some microprocessor setup information to program them.
Page 74: Option 2 Board
Option 2 Board The Option 2 board produces the additional serial digital test signals that are available when Option 2 is installed in the SPG 422. The circuitry is identical to the Bars generation in the standard instrument. The Test Signal Generator is a complete generator, requiring only a master clock, a synchronous frame reset, and some setup information from the microprocessor.
