Model 75P-223 is a 75Ohm solid-state programmable attenuator from JFW Industries with attenuation range 0 to 63.75dB by 0.25dB steps. It operates at 5-2150MHz and is rated for +23dBm of RF input power. This step attenuator is available with 75Ohm BNC, F or N female RF connectors.

The attenuator has seven individually controlled attenuation steps: 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB, 16dB and 32dB.

For larger RF test setups that require attenuation of multiple channels, model 75PA-118-XX is an attenuator assembly that is available with up to 16 individually controlled attenuators.

It has the same RF specifications as 75P-223, but comes in a 19in. rack mount chassis with Ethernet and Serial connections for remote control.

The 75PA-118-XX ships with a GUI test program that allows easy control of all programmable attenuators for DOCSIS attenuation fade testing.
