1604A Digital Distribution Amplifier with Remote M/C

Building on the success of the 1204A Digital Distribution amplifier, the 1604A provides additional high performance digital outputs, and enhances this with a full remote monitor and control interface.

With the monitor and control, a remote user can easily monitor status of each of the inputs/outputs of the unit on either RS232 or Ethernet with Telnet, web browser and SNMP interfaces. Optionally the unit can take two separate inputs into an input switch with either fully automatic or manual control.

For added flexibility, individual outputs can be enabled/disabled via remote control so that unused outputs are isolated from the alarm system.

Input and output status is immediately evident from front panel indicators of each channel. Also auto/manual selection of the auto switched input is available from the front panel key pad.

Isolation output to output is >100 dB. The unit provides 5V TTL, 50 ohm outputs, and all outputs are provided on convenient BNC connectors.

 Input frequencies DC to 30MHz
 16 Digital Outputs
 Isolation (>100dB typical)
 Remote Monitoring Outputs
 Remote Selection of Active Outputs
 Input Auto Switch (option)
 Low Cost
 Convenient 1U, 19″ rack mount package
