Proof of
Performance Test
The Proof of Performance test is a video channels test that can be
configured to run at a scheduled interval. An RF plant that passes this
test meets the minimum requirements for the delivery of video
services. When necessary, you can troubleshoot an installation by
performing this test at various locations to determine which compo-
nents require repair or replacement. You can save test results for later
reference.
Use scheduled tests for:
– 24 Hour AutoTests (per FCC)
– AutoTests with C/N, Hum & BER
– AutoTests that automatically run at a scheduled interval
