Product Description
The SPG 422 is a component digital, sync pulse generator (SPG). The SPG 422
provides basic setup and timing signals for component digital tape recorders and
processing equipment systems. It provides audio tones and a few simple video
test signals needed to adjust equipment and stripe video tapes. Analog black
signals are the timing reference signals of choice and the SPG 422 provides up to
six analog black signals, each with separate timing controls. Because the
SPG 422 has good frequency stability, it can perform as a stand-alone generator
or genlock to an external PAL or NTSC signal.
Some installations use 525/59.94 and 625/50 Component signals simultaneously
or switch between standards regularly. The SPG 422 architecture supports
dual-standard operation. 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.
The SPG 422 has a front-panel interface that controls all instrument functions.
Also, you can control the SPG 422 with 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.

The front panel has four sections: the Menu Display, the Menu Control buttons,
the Select buttons, and the Reference LEDs. (See Figure 1–2.)
This section of the front panel displays the current state of the SPG 422. Also
used in conjunction with the Select and Menu Control buttons to change the
configuration of the outputs.
This section of the front panel controls the Menu Display. The direction arrows
control scrolling through the menu, while the Enter and Exit buttons accept

changes or allow you to return to your original starting point. The LOCKOUT
button is included in this group. See Installation in this section of the manual for
details on the LOCKOUT button.
Use the select button to select a specific menu.
The reference LEDs indicate whether the SPG 422 is externally genlocked or is
using its internal oscillator.
More information on these controls is available in the Operating Basics and
Reference sections of this manual.

Power Connector. This instrument operates from a single-phase power source
with one current-carrying conductor at or near earth-ground (the neutral
conductor). Only the line conductor is fused for over current protection. Mains
frequency is 50 or 60 Hz. The operating voltage range is continuous from 90 to
250 VAC.
WARNING. To avoid dangerous electical shock, do not connect power to the
SPG 422 when the top cover is off. Dangerous potentials are present on the
Power Supply board.
Serial Bars. Serial digital color bars output. Set from the Serial Bars menu.
Serial Black. Serial Digital Black signal output. All its parameters are set by the
Serial Bars menu.

Genlock 1 and 2. Accepts analog black burst or CW as the genlock input. Burst
locks to NTSC and PAL Composite signals, sync locks to monochrome 525 and
626 signals, and CW lock to 1, 5, 10, 4.43, and 3.58 MHz. There are two
termination options: loopthrough or single-ended. The loopthrough option
requires external termination. When using the single-ended option, both inputs
are internally terminated and you may select either as the genlock source.
Black 1. Analog black output 1. Set from the Black 1 menu.
Black 2. Analog black output 2. Set from the Black 2 menu.
Black 3. Analog black output 3 (option 1 only). Set from the Black 3 menu. (This
connector is plugged in the standard instrument.)
Black 4. Analog black output 4 (option 1 only). Set from the Black 4 menu. (This
connector is plugged in the standard instrument.)
Black 5. Analog black output 5 (option 1 only). Set from the Black 5 menu. (This
connector is plugged in the standard instrument.)
Black 6. Analog black output 6 (option 1 only). Set from the Black 6 menu. (This
connector is plugged in the standard instrument.)
Serial Signals (2). Serial Digital Test signal outputs (option 2 only). (These
connectors are plugged in the standard instrument.) Select the outputs from the
Serial signals menu.
Remote. A 9-pin D-connector. Configure it as either a 9-pin ground-closure or a
9-pin RS-232 serial remote control. Select the configuration by moving the cable
connector within the instrument.
Serial Audio 1+2 and Serial Audio 3+4 (BNC connector). AES/EBU serial digital
audio output for channels 1 & 2 and 3 & 4 respectively. Set from the Serial
Audio menu.
Serial Audio 1+2 and Serial Audio 3+4 (XLR connector). AES/EBU serial digital
audio output for channels 1 & 2 and 3 & 4 respectively. Set from the Serial
Audio menu.
