Thanks! I will do that.

Sorry guys and gals: How many times must this point be made? ????????????? Resolution (point-to-point spacing) = Frequency Range / 101. Not using external

Not needed systematically if you use nanovna-saver. If you do a calibration between 1 and 900 Mhz with 20 segments (for instance) this makes 20X101 points = 2020 points or 1 point every 450 khz

You would do a bit better to cap the second port with the 50-ohm load. S21 or S12 are not involved in what you are doing. Any reading is due to crosstalk and lack of shielding and proper decoupling

Since the NanoVNA only has 101 point sweeps, when you calibrate from1 to 900 MHz, you have calibrated points every 8.9 MHz. So, suppose you wanted to sweep a 7 MHz bandpass filter for a 40 meter rig

Use Display setup -- *** nothing is permanent only change ( http://ha3hz.hu/ ) ***

S21 isn't used in your antenna tuning context. You can turn off this trace to avoid confusion, unless you like the "modern art" it produces on the screen. The USB C port doesn't need to speak "To-Go"

Answer: YES. When the range changes, calibration must be performed. The number of calibration / measurement points is 101 on the basic unit. 73, Gyula HA3HZ -- *** read more on this site (

Your photo shows S21 phase on the display. This is the phase of the (weak) S21 leakage. If you change it to magnitude, you will see the leakage signal strength. When using the VNA as an antenna

Recalibrate. The number of calibration points is limited. w.

Hello all, Quick question please. If I calibrate my nano from 1Mhz to 900Mhz and I want to change my frequency to 7Mhz to 71Mhz do i have to calibrate again or is this still in range of the original

Are you aware there is a -F variant specific group? Regarding S21 have you made a SOLT calibration in the frequency range of interest? A ter?a, 2/06/2020, 19:52, <wsanders@...> escreveu:

I am using the NanoVNA-F to tune a 75m mobile antenna (see picture.) There is an interesting pattern on the S21 trace. The VNA has been calibrated only using SOL (short-open-load). I have S21 "capped"

Does all of this mean that the RL on the NanoVNA and VNA Saver are wrong and should be positive??Deon

Herb, Thank you for your message and? explanations for use above 300 Mhz. Most of time, i use the VNA from 1.8 to 146 MHz but sometimes until 440 MHz. For this reason, i will follow your

BTW, I created a guide for nanoVNA users to use QUCS here https://hexandflex.com/2020/01/11/impedance-matching-with-qucs-studio-and-vna/

QUCS studio has a simulation block that accepts Touchstone files. It's the closest free software to ADS. I suspect you can also load them into the free demo CopperMountain VNA software.

Here are some tips for those that may wish to duplicate this box design which has a front panel size of 92mm x 38mm: - The hole centers for the two end connectors, "L" & "THRU" are 15mm from the ends.
