BAVM-860 SAW Series
Instruction Manual
Section 4 – Preparation for Use & Typical Application
After installing the unit, make the following adjustments:
4.1 Audio Modulation
With audio source connected, adjust Audio Modulation control for 25 kHz deviation. In lieu of an audio modulation meter,
use a TV set and adjust for equal volume as compared to a known off-air broadcast. Monitor for a few minutes to assure
the maximum volume does not over modulate, which can cause picture distortion.
4.2 Video Modulation
With a nominal 1 volt P-P video source connected, adjust the Video Modulation control for 85% depth of modulation. If
a spectrum analyzer is not available, a TV set can be used to check for proper picture contrast.
