Keysight J7201B Attenuation Control Unit

Features

• Includes option 001 Type-N(f) connector
• Attenuation sweep function: define the sweep time, number of cycles, and step size for your application
• Relative attenuation step function: set attenuation relative to any value
• Attenuation steps: 0 to 121 dB, 121 to 0 dB, or back and forth for the preset number of cycles (1 to 1,000)
• User selectable sweep time: 50 ms to 10 s, 50-ms increments
• 0.03-dB insertion loss repeatability typical per section for the entire 5 million cycles
• GPIB, USB, and LAN connectivity (LXI Class C Compliant) allow easy remote control and triggering
• Designed in a compact half-rack, 2-unit high form factor

The Keysight J7201B attenuation control unit delivers a comprehensive solution tailored for R&D and production engineers working in wireless communications, aerospace and defense, and electronic components. It supports frequencies from DC to 18 GHz and offers attenuation levels up to 121 dB in precise 1-dB increments. Its advanced sweep function allows users to customize parameters such as start and stop attenuation, step size, dwell time, and cycle count to suit specific applications. With typical insertion loss repeatability of less than 0.03 dB per section across 5 million cycles, the J7201B ensures long-term reliability and helps lower overall ownership costs.

Typical Applications

J7201B 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.
