Keysight Technologies Inc. USB Preamplifier, 10 MHz - 4 GHz
The U7227A, 10 MHz to 4 GHz USB preamplifier is designed to bring reliable gain and low noise figure to measurement systems improving the overall system performance and reduce systematic errors; a total solution to the X-Series signal analyzers to perform noise figure measurements.
When connected to the X-Series signal analyzers, the USB preamplifiers can automatically configure the analyzers to detect the specific preamplifier connected, and download 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 actual measurement made.
