    Getting Started This section provides the information necessary to install and become familiar with the SPG 422 Component Digital Sync Generator in its operating environ- ment. It includes a discussion of the rear-panel connectors, electrical and mechanical installation, setting for the internal jumpers, and a tutorial to become familiar with the menu and front panel operation.

  • Page 18: Figure 1-2: Illustration Of The Spg 422 Front Panel

    Getting Started 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.

    Getting Started 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. Select Buttons Use the select button to select a specific menu. Reference LEDs The reference LEDs indicate whether the SPG 422 is externally genlocked or is using its internal oscillator.
  • Page 20 Getting Started 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.

    Getting Started Rackmounting The SPG 422 comes with the hardware for rackmounting. The instrument fits in a standard 19-inch rack. Spacing between the front rails of the rack must be at least 17-3/4 inches to allow clearance for the slide-out tracks. Rack slides conveniently mount in any rack that has a front-to-rear rail spacing between 15-1/2 and 28 inches.
