Based upon my DDS-VFO and a simple antenna analyzer byIW3HEV i build this microcontrolled VNA. The S-parameters S11 and S21 can be measured. The measurement results can be transfered via RS232 or USB (from which the VNA can be powered). The project is in progress...

Based on the original programmer by DL2TM, i developed a SMD version with a few enhancements. The programmer works for the AT89C2051 and AT89C4051 micros.
