Attenuator assemblies with Ethernet and Serial remote controls from JFW Industries, Inc.

Attenuator Assemblies

We can package any of our solid-state or electro-mechanical attenuators into a remotely controlled attenuator assembly.  The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.

    19 Inch Rack Attenuator Assemblies (50 Ohm)

    Below is a sortable table of 50 Ohm programmable attenuator assemblies with 19 inch rack mount enclosures. The attenuators are step attenuator type. The relay step attenuators are electro-mechanical and have typical lifetime of 1 million operations. The solid-state step attenuators have no moving parts so there are no mechanical wear concerns. Solid-state attenuators have typical MTBF of 250,000 hours.

    Remote Control

    Our test systems are available with Ethernet, Serial, or GPIB 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.

    Fast Delivery Models

    JFW offers typical delivery times of 4 weeks or less for models 50PA-125-XX, 50PA-126-XX, and 50PA-128-XX. [lt id="1"]

    Demo Units Available

    JFW does stock some attenuator assemblies as demo units.  Contact our sales department for availability.  If you want to try out our firmware, then check out the online Ethernet Test Box running our latest generation firmware.

  • 19 Inch Rack Attenuator Assemblies with Manual Lever Controls

    19 Inch Rack Attenuator Assemblies with Manual Lever Controls (4)

    50PA-839 SMA eight channel attenuator assembly with manual controls and Ethernet/Serial remote control19 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. [lt id="19"]
