Yes, for the most part.? Let's say you have the original NanoVNA which uses 101 points. Your original cal is 101 points over the 27 MHz between 3 and 30, so about 270 kHz/point.? If you "zoom in" to

When you do a calibration open/short/50, Stimulus from 3 to 30 Mhz. it should then be accurate between 3 and 30 Mhz correct? OK you calibrated with the 3 to 30 Mhz scan width. Now if you change the

Excellent explanation Gregg - thanks! I also stepped into the same trap

Hello to the group, I have tried this before but ran into such a brick wall that I had to walk away from it. That said some time has passed and I am trying this again. I have a semi newer H4 Version

I wouldn't normally design a 100 ohm system using 50 ohm transmission lines and innerconnects and then compound it with stubs but I was going off your original comment of works meaning no loss of

I don't see any reason why you'd need 100 ohm cables. You'd replace the bridge (CH0) and pad (CH1) components to make it 100 ohms, the short cable to the T would make some difference, but at 900 MHz

Most software implementations expect arguments to trig functions in radians while most calculators expect degrees.? If you use GNU Octave, there are now functions for either.? sin(theta) expects

In my original post, I had not considered using different stub lengths. That's a good twist. 100 ohm cable and connectors may pose a problem. It seems like the definition of works has changed to

rho = 10^(mag S11/10) gamma = rho * cos(phase) + j * rho * sin(phase) Z = Z0 * (1+gamma)/(1-gamma) if you are doing it in Excel rho = 10^(S11/10)

The version of the nanoVNA that I have allows me to display the smith chart values in various different formats, including R + jX. I made a video on this last night and uploaded to YouTube.

NanoVNA can show R + jX on Smith chart (use MARKER->SMITH VALUE option for select Smith display data format) Or use Display->Format->Resistance Display->Format->Reactance

You can convert the magnitude and phase of S11 under one port measurements to R + jX which might be more useful for you. I forgot the formulas now.

I would assume you'd do a cal in NanoVNA-Saver - the idea behind the "rough wideband cal" is to make sure you're not sending data to NanoVNA-Saver that it doe

Jim , If he is calibrated on 50 KHz. to 900 MHz. and then sets the NanoVNA Saver to 1 1MHz-61MHz. there will be a lot of interpolation going on. Why not recall 2 and avoid this? Mike - N2MS - Try both

Nope.. You can probably just turn it on (which recalls 0) and go from that.

6 to 8 MHz and the center is 7.1 MHz.

Roger, My NanoVNA-H4 presently has the following calibrated and saved configurations. Recall 0 50kHz-900MHz Recall 1 1MHz-31MHz Recall 2 1MHz-61MHz Recall 3 100MHz-200MHz If I want to use NanoVNA

Jim, You don't have to calibrate In NanoVNA saver if the NanoVNA is calibrated and you are using the same frequency range in Saver. Roger
