SW AV Series Switchers • Introduction

Bandwidth

 — Bandwidth is 250 MHz (-3dB).  This high bandwidth allows the

switchers to switch all of the quad standard video formats with no loss of
signal quality.

All video models

Input sensing —

 The switcher continuously monitors all inputs to sense when the

input signal is active or inactive.  The switcher reports changes in the status
of each input (active to inactive or inactive to active) on the RS-232 port.

Autoswitching mode —

 When autoswitching is enabled, the switcher

automatically switches to the highest-numbered input with video sync pulses
present.  If video is absent from all inputs, input 1 is selected.
