Below is a sortable table containing our online 19 inch rack mount programmable attenuator assembly models. These models have evolved from over 30 years of designing and delivering custom RF test systems. If you can’t find a model that fits your needs, please email your requirements to our test system engineers ( jfwengr@jfwindustries.com). JFW does not charge NRE’s and our pricing for custom models is in-line with our catalog models. JFW has a wide selection of variable attenuators that we can use to manufacture a remotely controlled variable attenuator assembly for you. JFW can take any of our catalog programmable attenuator models (solid-state or electro-mechanical) and integrate it with a variety of remote and manual control options. |

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(sales@jfwindustries.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. | | | | 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. |
| | | Options | | Attenuators: | | Electro-mechanical (DC-18GHz) or Solid-State (0.001-6GHz) | | Remote Control: | | Ethernet, RS-232, GPIB, or TTL | | Manual Control: | | Keypad (w/ LCD) or toggle switches | | Enclosures: | | Benchtop or 19", 23", 24" rack enclosures | | Supplied Power: | | AC, Dual redundant AC, or DC powered | | RF Connectors: | | BNC, TNC, SMA, N, etc. | | Impedance: | | 50 Ohm or 75 Ohm |
