Thank you very much Gen Hu for reincarnation s-a-a-2 V2 and dislord thanks for refining the software and new versions. The device on harmonics pulls more than 8 GHz with permissible noise. Shop and seller recommend.

Seems OK, calibration was OK, test of several attenuators proved that there should be no nonlinearities in the design. There was even a basic set of calibration standards included.

Another nanovna for family. Excellent equipment. Took just 15 days to be delivered. Igor Jobim - PY3IG

The device is excellent. In the photo for the PGIMER, the dimension of the antenna is 868 MHz.

Drove a month, despite the new year. Turned on-works. I have not done the measurements yet.
