Review on Set Of 4 AURSINC SAA-2N V2.2 Vector Network Analyzer Calibration Tools: N-Type Male Short, Load And Open, Female To Female Connector For Improved SEO Results by Bryan Maignan

Everything about this unit is great with a couple of minor exceptions. The weight is a trade off between the shielding of the metal case and the weight of the metal case. Accuracy is great; comparable to my Array Solutions AIM that's four times the price. And it has added functions like S12 AND S11. I bought mine through Aliexpress for $70 before it was offered on Revain. The carrying case is a big plus. The big annoyance is that it doesn't turn ON with the default Calibration and previous Setup. First, you load the desired CAL and then the desired configuration. I also use a stylus with mine to improve usability; highly recommended. It's supplied with a guitar-pick type plastic stylus but my pen-style stylus is much more convenient for me.
