Description
There are several cases where VNA measurements need to be taken at a single frequency over time or space instead of frequency. For example, when testing a multi-element (phased array) antenna and need to check amplitude and phase (S21) from feed point to each element and/or reverse.
Would it be possible to select first a single Frequency and Power setting and then select:
(a) either a Time period of measurement (in Seconds)
or (b) a number of discrete measurement steps (and advance manually from one to next) ?
You would then need to rescale the x-axis to accommodate the selected time period (in sec) or the number of discrete steps.
You could also ask user specify the number of samples to average at each step.
Finally, save the measurement to a text delimited file format for further processing, like Near-to-Far field transformation by MATLAB.
If such a measurement mode could be possible, would open for xaVNA a whole new range of applications that are not found at any low-cost VNAs.
