CVB/VDA (# 100-0-001): The clamping action of the CVB/VDA corrects for 60 Hz hum, improper DC offset, and
other low frequency interference in the input signal by clamping the output sync-tips to a fixed level. This correction is
effective even if the signal and hum have been transmitted by microwave, satellite or fiber. An adjustable clamp level
allows use with systems that require the sync-tips to be clamped to some level other than -40 IRE (-0.286 volts). The
CVB/VDA provides an adjustable gain range of 0.5X to 2.0X and is designed to clamp properly when the output video
signal is set to 1Vpp (140 IRE).
