Improve overall system performance and reduce systematic errors through excellent noise figure and optimized gain


The U7227A USB preamplifier (10 MHz to 4 GHz) brings reliable gain and low noise figure to measurement systems. It improves the overall system performance and reduces systematic errors.

When connected to an X-Series signal analyzer, the USB preamplifier automatically configures the analyzers to detect the specific preamplifier connected, and downloads the embedded calibration data such as gain, noise figure and S-parameters. The calibration data provides accurate correction data and more repeatable results for each measurement.

Embedded smart features and benefits:

  • Automatic temperature-compensated gain corrections and calibration data transfer (noise figure and S-parameters) through USB plug-and-play improve noise figure measurements with Keysight X-Series signal analyzers
  • Excellent noise figure and optimized gain with the X-Series signal analyzers improves measurement accuracy and minimizes uncertainty
  • Broadband operating frequency from 10 MHz up to 4 GHz for various applications
  • Rugged and portable design for benchtop measurements or remote front-end field applications
