Hi goscickiw, > Yes, I know this, I mentioned that previously. If calibrating the whole system to 75 ohms is causing an issue that I haven't noticed yet, maybe the...

Hi goscickiw, yes, if you place a minimum loss pad you get right measurements at cost of the reduced dynamic of the port. This is because it is a pure...

By the way (this is just a provocation of course). Hugen could design and sold cheap SMA male to BNC female minimum loss pads for the nanoVNA. They are just...

Hi Joel, I don't want to teach something that you probably know better than me, but that offset is far too high to justify a bad clock compliance. The nanoVNA...

Hi Joel, I'm not sure, what do you mean with: "What signal should we expect if the stimulus output is set to sweep 10.0MHz to 10.0MHz?" Is that a zero...

By the way, take a look at this this Keysight application note: http://literature.cdn.keysight.com/litweb/pdf/5965-4972E.pdf In last paragraph figure 13, you can see a specific xtal test fixture to get accurate measurements...

Hi Joel, now I'm at my home workshop and I made what you said, that is I connected a SMA T to the S11 port and to my Rohde &...

I just replied you here: https://github.com/hugen79/NanoVNA-H/issues/46#issuecomment-711723428

Hi DisLord, Ok, to fix the glitches at the band change points do as follow. Substitute the **IS_HARMONIC_MODE(f)** macro with the function **int8_t IS_HARMONIC_MODE(uint32_t freq)** here below ``` int8_t IS_HARMONIC_MODE(uint32_t...

Hi Erik, I see the signals are very noisy in the that 500MHz...900MHz range. Do you already have done the mods discussed in the link below? https://github.com/hugen79/NanoVNA-H/issues/14 I use this...
