This is a short video demonstrating the performance of N1201SA RF Vector Impedance Analyzer in comparison with Diamond SX400 SWR meter on individual frequency check across the designed frequency 435-445 Mhz on a UHF 70cm Yagi. The advantage of course of the N1201SA over the Diamond SX400, is it can directly plot the frequency sweep analysis of the antenna very quickly on the LCD monitor. However when it comes to precision both of the devices gives out a similar readings with little variation from the analog display of SX400 as compared to N1201SA digital display.
