You don’t have to look hard to see the benefits of the Videotek® Compact Monitor Series — including the CMN-91 multiformat signal analyzer with integral LCD. The smallest solution on the market for efficient video and audio signal monitoring, the CMN-91 tests signal quality across all DTV formats up to 3 Gb/s. It possesses two SDI inputs and provides selectable waveform, vector, gamut, timing and picture full-screen display.
With the CMN-91 you can meter all 16 channels of embedded audio or one AES input. You can also view the waveform of the composite or tri-level external reference to verify signal integrity and customize the MLT display with independent size and position of waveform, vector and picture.
