NAC Inc. of Tokyo, together with NACoUS of Woodland Hills, California has for several years been developing a recorder, the V-315, for high bandwidth image signals such as those output by sensors for various reconnaissance applications. Such sensors have rapidly advanced in recent years. In order to check full system compatibility with such sensors, NAC's engineering model was integrated and subjected to (benign environment) flight testing last year. As a result of these successful tests, the decision was made to proceed to the development of pre-production units (the `flyable' units) of the V-315 for more extensive flight testing. Flyable High Bandwidth Analog Recorders are now in the final stages of development as described below.
A new high-speed video system, the model HSV-500, has recently been introduced into the market of motion analysis. It is in itself a complete stand-alone motion analysis workstation which allows the operator to capture high speed motion and view it at a slower rate. The HSV- 500 has the ability of recording up to 43 minutes of video at a rate of 250 or 500 pictures per second and playback at variable rates displaying the imagery on high resolution NTSC or PAL color monitors.

A helical scan, high bandwidth tape recorder, Model V-305, is being developed for hostile environmental applications, such as airborne reconnaissance. The V-305 has the capability of recording and reproduction on a single asynchronous analog channel with a minimum bandwidth of 12 MHz. The data will be recorded in analog form on a 1/2 inch format tape cassette. In addition, it has selectable/analog auxiliary channels and a 20 kHz analog channel. Control of the recorder is performed via MIL-STD-1553A/B and RS-422-A.
