Benchtop Attenuator Assemblies (75 Ohm)

Below is a sortable table for 75 Ohm programmable attenuator assemblies that are in benchtop style enclosures. Click on a column header to sort the column data as ascending or descending. Click on a model number to view its product page that displays the full specification sheet and outline drawing.

The models in this table were inspired by customer requests. If you do not find a model with the mechanical/electrical features that you require, please email your requests directly to our engineering department ( JFW does not charge NRE’s and will respond to your request with a quick cost estimate.

Capabilities & Options
Custom Models
The models listed in the above table showcase some of our standard programmable attenuator assemblies. However, most of JFW’s test system business involves custom designed models. JFW does not charge NRE’s for custom models. We encourage you to email us your specific requirement ( We will respond with a ROM (rough order of magnitude) quote in 1-2 days. Please include a block diagram with your request if the test system involves multiple RF components.

Remote Commands
JFW has standard remote commands for GPIB, Ethernet, and RS-232 controlled models. The command syntax is simple and allows easy control of the programmable attenuator settings. In addition to our standard commands, JFW can also provide customer specific commands upon request.

Test Software
JFW provides a GUI test program with all Ethernet and RS-232 controlled test systems. The test software for programmable attenuator assemblies has all of the remote commands built in for easy testing. In addition to the remote commands, the GUI test program has additional functionality such as keypress, handover, and indefinite handover. Check out our sample test programs to see for yourself.
