JFW model 50PA-839 N eight channel attenuator assembly with Ethernet/Serial remote control

19 Inch Rack Attenuator Assemblies with Manual Lever Controls

These 19 inch rack mount attenuator assemblies have lever switches for manual control. Each step attenuator has its own corresponding lever switch and display. The lever switches are momentary so you can manually “tap to step” or “hold to jog” to change the attenuation setting. The displays show the current attenuation setting at all times. If an attenuator is updated remotely, then the display will change accordingly. If you run a remote script, all attenuation changes will be displayed as they are executed.

Remote Control

The manual lever test system models are available with Ethernet/Serial remote control. The remote control features easy to use ASCII formatted remote commands. The step attenuators can be controlled individually (set attenuator command) or as a group (block command, set block command). All test systems with Ethernet/Serial control run out latest generation 3.x.x firmware. Use our Ethernet Test Box to demo the 3.x.x firmware.
