Automatic Testing Of Cable Television Decoders (1985)
By Lance J. Katzfey, Oak Communications Inc.
Many types of test equipment are avail ab 1 e which use the GPIB Bus (also known as IEEE 488 and HPIB Bus) for control and access. By using a personal computer and this test equipment, it is possible to fully automate the testing of a cable television decoder with a minimum of custom made parts. By using BASIC as the control language, anyone with experience in programming a personal computer can develop their own test programs.
We have developed programs for many tests including the following: headend calibration RF, video, and audio measurements; decoder box RF, video, and audio measurements; decoder beat measurements; and tuner gain and noise figure measurements.
