The unit consists of a twelve channel GPS receiver, the output of which is used to synchronize an IRIG B time code generator. The IRIG B signal is then used to drive the color and monochrome video sync generators. The 6140 provides a precise IRIG B serial time code output, an RS-170 composite video signal and an RS-170A (NTSC) composite signal with black burst. The unit automatically acquires all in-view satellites upon power up and locks the internal IRIG B time code generator to the GPS time reference. The Video Sync Generators then lock to the IRIG B. Lock status is displayed by LED indicators on the front panel. If the GPS lock is lost the 6140 will automatically switch to an internal clock and continue generating the output IRIG B signal. No discernible change in the IRIG B output or video sync will occur due to this transition.
The PM 5410 family from Fluke offers today's widest choice of TV and video test signals from a range of compact instruments. These state-of-the-art generators provide support for TV, VCR and video monitor testing in all the PAL, NTSC and SECAM standards. Their basic functionality includes test patterns and outputs to test and align the total signal paths for video, audio and data services such as the Teletext and Closed Caption. Signals are provided for testing overall picture geometry for both 4:3 and wide screen 16:9 aspect ratios, as well as specific parameters such as high-voltage stability, beam current, static and dynamic convergence, picture resolution, color purity and color reproduction, and all vision and sound demodulators.
