I would like to develop some antennas and require the means to test prototypes. I'm currently looking at used equipment ie. HP 8757A and I would like to find a testing schematic to better understand what equipment will be required, and how the test is to be configured. I wish to be able to measure antenna performance parameters quickly so I can develop reasonable prototype parameters, then have the ability to perform extensive measurements on the prototype as constructed. Can you steer me in the right direction?
