The TTC ACT-1000 Active Camera Target is a standalone device intended for laboratory use and camera setup verification. The ACT-1000 time display consists of over 200 LEDs arranged as a 6-digit display, four 10 LED rows and a 10 x 10 LED array. This display serves as a visual target for high-speed camera development and verification and for third party camera testing. The display can be configured in a range of different time formats and resolutions. The LED array allows measuring camera exposure times from 1 sec down to 1 usec. The internal Real Time Clock (RTC) automatically sets itself and tracks an externally provided IRIG-DC signal.
