From the NI MAX web site: "NI MAX is only supported on Windows and MacOS, not Linux, and cannot be downloaded by itself. It is included with all NI drivers (NI-VISA, NI-DAQmx etc.) and NI System

Thank you for your reply DiSlord. I looked at both PCBs, 10R resistor for 3.3V I put in position R2 on "LCD" PCB, MOSI signals, MISO, SCLK are available on H1 connector on "LCD" PCB. The problem will

The attenuators affect more than S11 SNR when used in this fashion They are not exactly 50 ohms input/output impedance. Also the calibration errors will probably be greater as the DUT impedance is

Need use any console software (like terminal, putty RealTerm) You receive list of error tetm (used by nanoVna as calibration data) 'data 2' ED - error term directivity 'data 3' ES - error term source

Hi, Luciano... I more or less (in my head) wrote off the "extra" resistance needed to make the NanoVNA see a flat match as being to a combination of lead resistance/reactance and operator error. I

Hi Charles, I get "suspicious" when I see small differences like this i.e. 50 ohm as in this case. Assuming the black box is lossless, you should measure either 2450 or 2500 ohm if you load the other

I do not understand what you mean. Do you mean the nanovna-saver.exe window (mostly black with some status lines on it: I am not able to do a command from there)? Or is there some console within the

I worked for PWA for decades and was the only engineer that used LabVIEW, now all the engineers do. It is very easy to learn (very friendly for EEs) and yes it is expensive. So I am glad to see that

Great! Thanks. Any google search I attempted lead me to the RSGB website, which was a dead end for me. I did realize the forums were right here on groups.io, duh.

Hello, All... I recently had a need to measure an unknown matching transformer. As it was in a sealed enclosure with noth but the wire terminal and coax connector exposed, and I didn't want to damage

What's the ripple in the measurement from? A reduced SNR would give a random error, not a periodic one, but maybe it's a manifestation of a phase bias that is contributing more or less depending on

on real amplifiers, with non zero S12, the load impedance does show up at the input - imagine an amplifier with S12 of -10 dB and a S11 of -100dB.? A total reflection at the output of the amp will

This is what I get using an inductor (7 turns of RG58A through a toroid) and the component is connected to CH0 and calibrated: [image: afbeelding.png] You see the S11 |Z| graph is a straight line

Dave - Thanks once again for all the information. I'll test the modification using the 1/8 wavelength frequency in SimSmith and see how it compares. That change also allows the method posted by John

Did a quick search for RSGB sites as described but didn't have any luck. Could you provide a link or more info to help find them? TNX
