J7211B Attenuation Control Unit, 18 GHz, 121 dB, 1 dB Step

An Integrated Attenuation Solution for Wireless Communication

The Keysight J7211B attenuation control unit provides an integrated solution for R&D and manufacturing engineers in wireless communication, aerospace and defense, and electronic component industries. Operating from DC to 18 GHz, the J7211B provides attenuation up to 121 dB with a 1 dB step size. A unique attenuation sweep function lets you select start and stop attenuation, step size, dwell time, and number of cycles for your application. The J7211B offers exceptional < 0.03 dB insertion loss repeatability per section for the entire 5 million cycles, reducing your cost of ownership.

Designed in a compact half-rack, two-unit-high form factor, the Keysight J7211B 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

The J7211B attenuation control unit’s attenuation sweep function lets you design, validate, and manufacture WiMAX™ and WLAN components and for mobile handset base transceiver station handover test.

Attenuator Control Capability

• attenuation sweep function: defines the sweep time, number of cycles, and step size for your application
