Model Details

The CM125 "PIX PAK" is small, but it packs a powerful pixel punch with 125 MHz video bandwidth and 2048 x 2048 pixel resolution. The sync, pixel, and blanking times are also fully programmable so you can adjust to match the monitor under test. The "PIX PAK" is also compatible with TTL, analog, and ECL video types so you're ready for any computer monitor. The CM125 has storage locations for 100 computer monitor formats with the most popular formats in 43 preprogrammed locations. You just recall the storage location, and start testing. A complete set of dynamic video patterns help test the performance and operation of monitors and point you toward defective circuits. Plus, a special pattern sequence feature lets you automatically cycle the patterns several times a minute to prevent phosphor burns. The "PIX PAK" gives you these patterns: Raster, Windows, Circle/Cross, Multiburst, Color Bars, Text and Staircase.
