J7211A Attenuation Control Unit, DC to 6 GHz, 0 to 121 dB, 1 dB step

An integrated attenuation solution for wireless communication

J7211A attenuation control units provide an integrated solution for R&D and manufacturing engineers in wireless communication, aerospace and defense and electronic component industries. Operating from DC to 6 GHz, the J7211A provides attenuation up to 121 dB with a 1 dB step size. A unique attenuation sweep function lets you select the start/stop attenuation, step size, dwell time and number of cycles for your application. J7211A offers exceptional < 0.03 dB insertion loss repeatability per section for the entire 5 million cycles which reduces your cost of ownership.

Designed in a compact half-rack, 2 unit high-form factor, the Keysight J7211A ensures ease-of-use in benchtop applications and greater efficiency and throughput in ATE testing. GPIB, USB and LAN connectivity (LXI Class C Compliant) allow easy remote control and triggering.

Typical applications

J7211A attenuation control unit's attenuation sweep function makes it ideal for designing, validating and manufacturing WiMAX™ and WLAN components and for mobile handset base transceiver station (BTS) handover test.
