Capabilities & Options
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 (email@example.com). 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.
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.
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.
