The Model SSC/623 Stroke-to-Raster Scan Converter with Mixer converts stroke video from XYZ vector to a standard raster video format. The converted video can then be mixed or keyed with an external video signal. Stroke video is generated by a variety of random deflection devices, including certain radar and sonar devices, spectrum analyzers, and Heads Up Display (HUD) generators. A choice of four video standard outputs is provided: RS-170, NTSC, PAL, or 875-line RS-343. After conversion, the video can be recorded using standard TV cassette recorders and viewed using low cost, off-the-shelf monitors.

This model has two separate analog input processing channels. Each channel has separate gain and offset adjustments for X, Y, and Z. Either channel can be routed to the scan converter. Control and individual channel calibration is provided through the unit’s front panel display, keypad and control knob or remote control RS-232 serial port.

High quality video is generated by a combination of high frequency sampling and an advanced scaling algorithm. Scaling is an important consideration when converting computer-generated graphics or alpha numerics to a raster format.

The SSC/623 also includes an internal test signal generator that can be used to either confirm proper operation or to provide fault isolation.

The SSC/623 can be synchronized (or genlocked) to an external video input. Once genlocked, the external video signal can be mixed with the scan converted video to provide a composite video output. The mixer mode can be selected for linear mix, non-additive mix, self key, or matte key. Additionally, in the NTSC or PAL output mode, a matte key color can be selected.
