General
The AVS-3170 5 x 1 relay switcher for video and RF is a passive unbalanced circuit relay switcher.
The relays used are low capacitance reed relays wired to minimise crosstalk from the unused inputs and thus allow the switcher to be used with RF or video signals exceeding 140 MHz.
This also allows the switcher to be used for highspeed digital signals with minimal effect on the pulse risetime.
When used at very high data rates the small amount of high frequency attenuation may be corrected by following the switcher with a data distribution amplifier. This not only provides automatic equalisation, but also source isolation and multiple outputs.
Termination resistors for 75Ω signals are fitted as standard. These may be easily changed to 50Ω for RF signals or removed for switching TTL or other signals. |
When the switcher is not powered, relay 1 circuit switches input 1 to the output thus providing a secure path during power failures.
The AVS-3170 5 x 1 relay switcher is designed to interface with other IRT Eurocard 3000 series switchers or with the VG-737 video and AG-738 audio program fail detectors.
The switcher may be fitted with a local control panel, type CPS-3050, or with a tally panel, type TPS-3010, for local path indication when the switcher is operated remotely.
The AVS-3170 is built to the IRT Eurocard format and may be mounted in any of IRT's standard Eurocard frames together with other Eurocard modules. |
