Programmable Attenuators
JFW programmable attenuator models are step attenuators that are available with 50 Ohm or 75 Ohm impedance. We offer models with relay (electro-mechanical) or solid-state design. The programmable attenuators can be controlled with TTL, +Vdc or USB. We also offer attenuator assemblies with Ethernet controls.
50 Ohm Models
- Relay: step attenuator with +Vdc or TTL control
- Solid-State (TTL control): step attenuator with TTL control
- Solid-State (USB control): step attenuator with USB control
75 Ohm Models
- Relay: step attenuator with +Vdc or TTL control
- Solid-State: step attenuator with TTL control
