CMN-91

Multiformat Signal Analyzer

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.

Features

  • Available with SD, HD/SD or 3G/HD/SD inputs
  • SD and HD/SD can be upgraded to 3G/HD/SD
  • Metering of all 16 channels of embedded audio
  • One AES audio input
  • Two active looping SDI inputs
  • Quad display of audio, picture, waveform and vector
  • Thumbnail picture with adjustable size and position
  • Waveform display of external reference or LTC input
  • Overlay display with independent size and position of waveform, vector and picture
  • DVI-D external display output
  • 99 presets
  • Standard four-pin XLR DC power input (AC adapter supplied)
  • Anton-Bauer or IDX battery mount options
  • Convection cooled, silent operation (no fan)
  • Front-panel headphone jack
  • Front-panel USB port for save/recall of presets, screen captures and SDI captures
  • Dual rackmount option
  • Portable case with handle and tripod mount option

Product Details

The CMN-91 is available with either SD, HD/SD or 3G/HD/SD inputs. The SD and HD/SD models are fully upgradeable to 3G/HD/SD.

A standard 11-17 VDC power input and optional battery mount provide flexible powering for both fixed installations and field operation. Low power consumption allows the use of convection cooling for energy-saving, silent operation.

The CMN-91 is extremely lightweight and is available as portable or rackmountable. The unit has a compact half-rack footprint less than seven inches deep — a short mounting depth that integrates easily in today’s space-constrained facilities.
