 |
|
The FS730/4 Series Distribution Amplifiers are used to distribute broadband (DC-100 MHz) analog signals over 50 Ω coax. Each amplifier has one input and seven outputs, all on BNC connectors. The input and outputs are DC coupled with a 50 Ω impedance. Applications include the distribution of frequency references, IRIG timing signals, composite video, audio, etc.
There are four indicator LEDs. The “power” LED indicates that the unit has AC power. The “signal” LED indicates that an input signal greater that 300 mV is present. The “overload” LED indicates that the input signal has exceeded ± 2 V.

Configuration
The FS73x series of products can be configured as half-width, 1U, benchtop instruments (FS730) shown above, or in full-width, 1U, 19" rack-mount enclosures (FS735) shown below.
The FS730/4 model provides 7 output BNC connectors on the front panel, and can be rack mounted with an optional rack mount kit.
The FS735/4/4 model provides 14 output BNC connectors on the rear panel, with status indicators on the front panel. Several types of distribution amplifiers are available as listed below. Different types may be combined within the FS735 chassis.
