Application Note: 4-Port AutoCal® Scorpion®

Automatic calibration techniques for Vector Network Analyzers (VNAs) have long been known as convenient transfer-standard techniques for calibration that avoid many connections and user errors. With the advent of multiport VNAs, the need for automatic calibration increases since the number of manual cal connections increases. This application note will discuss a 4 port AutoCal® module (36584KF and 36584NF), how it works, how it can be practically used, and how uncertainties are affected.
