Benchtop Attenuator Assemblies (50 Ohm)

Below is a sortable table of 50 Ohm programmable attenuator assemblies with benchtop 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. The manual for the 3.x.x firmware lists the remote command syntax with examples. We also have sample GUI test programs available that work with models running the 3.x.x firmware.

Custom Models
If you do not find a model on the website that meets your requirements, please use our inquiry form or email our engineering department. We will respond with a quick cost estimate. JFW does not charge NRE fees for new models. A large portion of the RF test systems that we manufacture are per custom requests.
