BER - Bit Error Rate

C/N: Carrier to Noise Ratio

dB - Decibel

dBm - Decibels referenced to one milliwatt

dBmV - Decibels referenced to one millivolt

dBµV - Decibels referenced to one microvolt

Delta V/A - Delta Video to Audio - Calculated by subtracting the (first if DUAL) audio carrier level from the video carrier level (for analog TV and DUAL type channels only)
