Noise performance test results

Results of extensive noise floor testing of the dual detector VNA v4.0 and v4.1 boards

This page has information about the noise tests I done on the dual detector boards. The following screenshot shows a typical noise level for the Detector 1 and 2 when the VNA is set to use Corelated Double Sampling (CDS) which helps eliminate the noise floor drift caused by the small offset voltge existing at the detector output. It can be seen the dynamic range of the VNA is 120dB through to 60MHz.

Thanks for reading and have a good time assembling your VNA.
