Gopan VU2XTO has done an amazing hack. He packaged an F4GOH VNA together with an RaspberryPI 3, an LCD touch display, a touch pad and a small OLED display in a little box and - voila his standalone VNA is ready to go.
Here a short description from Gopan how he did this - for any questionx regarding his solution, please contact him directly.
Some months ago Andrew Rich, VK4TEC and Geoff Robinson, VK4KJJ provided me a chart where they measured the generator output level over frequency:
They used a ROHDE & SCHWARZ NRP2 with an NRP-Z81 power sensor.
