Hugen Can I suggest you use the same values of R25 and R24 in the attenuator circuit for the CH1 input as those used in for the reference SA612? And then set R22 to come to 50 ohm? This will reduce

thanks Hugen! but unfortunately I haven't a spare cable and can't go out to buy one: thanks COVID-19! hahaha I checked the socket and it's OK: I didn't need to enlarge the hole of the case. Claudio

In the immortal words of Arte Johnson...verry interesting... In over 20 + replies only handful actually answered or came close to answer my question. As of now , here are MY observations. The Smith

The Smith Chart is a plot of the reflection coefficient where it's magnitude covers 0 to 1 having a phase angle from 0 to 360 degrees (0 to 2pi radians) (vector....mag and phase angle). The

Another solution comes from the suggestion of Massimo. Changing the input of SA612A to single-ended can eliminate the influence of the capacitance of one of the input pins. Maybe this modification is

Is the USB cable faulty? Try replacing the USB typeC cable.

Kerr, I was curious to see what would happen if the turns count was reduced to 7 from 8. The results were better with an improvement in S11 and S21. I have attached some plots showing the difference.
