19 Inch Rack Attenuator Assemblies (50 Ohm)
Below is a sortable table of 50 Ohm programmable attenuator assemblies with 19 inch rack mount enclosures. The attenuators are step attenuator type. The relay step attenuators are electro-mechanical and have typical lifetime of 1 million operations. The solid-state step attenuators have no moving parts so there are no mechanical wear concerns. Solid-state attenuators have typical MTBF of 250,000 hours.
Remote Control
Our test systems are available with Ethernet, Serial, or GPIB remote control. The remote control features easy to use ASCII formatted remote commands. The step attenuators can be controlled individually (set attenuator command) or as a group (block command, set block command). All test systems with Ethernet/Serial control run out latest generation 3.x.x firmware. Use our Ethernet Test Box to demo the 3.x.x firmware.
Fast Delivery Models
JFW offers typical delivery times of 4 weeks or less for models 50PA-125-XX, 50PA-126-XX, and 50PA-128-XX.
