SPECIFICATION SHEET JFW MODEL 50PA-976-XX PROGRAMMABLE ATTENUATOR ASSEMBLY JFW Industries, Inc. Phone: 317-887-1340 [email protected] www.jfwindustries.com Frequency Range 200-6000 MHz Attenuation Range 0-95 dB in 1 dB steps Configuration Individually controlled solid-state programmable attenuators. Number of attenuators can be selected from 1 to 4 attenuators. Manual Control & Display Momentary Lever Switches with 7-Segment LED Displays (current dB settings displayed at all times) (each attenuator has its own lever switch) (tap lever to step, hold lever to jog) (jog speed range is 0-10) (jog speed set to 0 will disable all levers) Enclosure Type 19 inch rack mount at 1RU high Impedance 50 Ohms nominal Startup/Default States (configurable) Attenuators to 95dB at startup (see ATTEN command) DHCP enabled (see NET command) 4 Ethernet users (see NET command) Prompts off (see PROMPT command) All of these default settings can be changed by user. Unit can be configured for up to 12 Ethernet users.
