Just to clarify Bryan. CH0 and CH1 are terminated into 50 ohm. So there is no
thru connection. And yet the vna and/ or the saver give a result of 0 dB for a
S21 measure?
Alan,
Only the nanoVNA-Saver shows 0.0 dB on the "S21 gain" plot. However, when you look at the real and imaginary plot, the values are 0.0 + j0.0. The device itself shows -inf and plots it as a very large attenuation for S21. When you use a terminal emulator to read values you can see that the result is 0.0 + j 0.0 also.
