Improve Signal Analyzer Test Accuracy by 10x
Even short cables can cause losses at millimeter-wave frequencies. See the true performance of your device using the U9361 RCal to move the reference plane in the measurement system to the output of your DUT. Two modes allow the device to operate as an absolute power reference or as a comb generator for complex calibration.
The Keysight U9361 RCal receiver calibrator allows you to correct linear errors in your signal analyzer measurement setup. Transfer absolute power accuracy (dBm) to your signal analyzer while generating flatness corrections in both magnitudes and phase up to 5 GHz IF bandwidths.
The palm-sized, USB-powered, and USB-controlled RCal gives you an ultra-stable reference and repeatable results. Seamlessly transfer precision factory calibration data to your Keysight X-Series signal analyzer over a USB connection. Drastically reduce the effort and complexity required to improve measurement accuracy for the test receiver system.
The U9361 RCal enables you to correct absolute power accuracy, magnitude flatness, and phase flatness with a single device. One RCal receiver calibrator eliminates the need for multiple pieces of test equipment to calibrate your signal analyzer.

Magnitude, also known as scalar, calibration allows you to sweep across the range of your device. RCal then corrects for path loss and inaccuracies found in the signal path, leading to increased intermediate frequency (IF) flatness. Complex calibration allows for phase calibration.
Perform Complex Calibrations
Using the RCal for complex calibration allows you to correct phase errors in your calibration path up to 110 GHz. Find out how to perform this calibration in this demo video.
