Return loss of open circuit after reducing the span and calibrating. Whereas, the individual open-short-load will calibrate the nanoVNA. In the case of the Keysight VNA, we will be using the 85561A 2.92mm 4 in 1 calibration kit. To do so, we will use respective calibration kits that come with the two devices. Calibration testĬalibration is the first step before you even begin to use your VNA. In this article, we will be testing a a low pass filter and an antenna and then comparing the measurement results from both the instruments. Additionally, this device can also operate as a Spectrum Analyzer mode to observe the frequency spectrum. In short, the N9952A has everything a professional RF design engineer requires. It offers a dynamic range of 70 to 100dB and comes with plenty of features such as Time domain reflectometry, adjustable output power, adjustable IF bandwidth, and so on. The Keysight Fieldfox N9952A can operate over 300kHz to whopping 50GHz. In this post, we will be looking at the two EXTREMES available in the market today the sub-hundred dollar nanoVNA and the Keysight fieldfox N9952A. For example, the $500 miniVNA and the sub-hundred dollar nanoVNA are very much affordable in comparison to the thousands of dollar equipment available out there. Very few VNAs are available to be bought by someone like you and me. Most of them are out of reach for a typical hobbyist. Vector network analysers (VNA) come in all sort of price ranges.
