It was found that the high frequency VNA was set for 50 MHz steps. Figure 10 shows the original phase data before ...A TRL cal with broad frequency coverage requires multiple LINE standards. For example, a span from 2 GHz to 26 GHz requires two line standards. Must be an appropriate electrical length for the frequency range: at each frequency, the phase difference between the THRU and the LINE should be greater than 20 degrees and less than 160 degrees.Keysight VNA Solutions.
