The Keysight (Agilent) J7211A is an integrated Attenuation Control Unit designed for R&D and manufacturing engineers in wireless communications, aerospace and defence, and electronic component test industries. Operating from DC to 6 GHz, it provides a wide attenuation range of 0 to 121 dB with a 1 dB step resolution. Its unique attenuation sweep function allows users to define start/stop attenuation levels, step size, dwell time, and the number of sweep cycles, making it ideal for handover testing and component characterisation.

The J7211A is built in a compact half-rack, 2U form factor suitable for both benchtop and ATE rack integration. GPIB, USB, and LAN interfaces are all standard, with LXI Class C compliance enabling straightforward remote control and system integration.

Key Features:
• <0.03 dB insertion loss repeatability per section over 5 million cycles
• Excellent attenuation accuracy and flatness across the full frequency range
• Calibrated data correction displays the exact corrected attenuation value
• Attenuation sweep function with user-defined dwell time, step size, and number of cycles (up to 1000)
• Relative attenuation step function — set attenuation relative to any reference value
• LXI Class C compliant — GPIB, USB, and LAN connectivity
