Re: Measuring inductance
for my saa2n i have cal standards with plugs (male connector) .. but i wanted also female (so i can calibrate at cable end with a plug without double female needed) so i took 3 N sockets .. one with

Re: Apologetic Intro Message
Wanted to add another "thank you" for posting that information. I've had nanoVNAs since they first emerged (2019?), and a ham friend recently gave me one dated from that era. Had never been updated,

Measurement correction for Zc Coax caracteristic Impedance
Hi DiSlord Coax Zc measurement function, already installed on H4 1.2.40 firmware, seems need to measure C0 capacitance @ 100Khz and the f0 first coax resonance frequency (Hz) and then we

Re: Measuring inductance
Please post the .s2p file. I'd like to calculate results using the Y21 method that suppresses stray, shunt capacitance in the test fixture. Brian

Re: Measuring inductance
Indeed, the HP16092A is the butt end of an APC-7 connector, with just 3mm of the centre conductor protruding beyond the insulator. It has an advertised max freq of 500 MHz. I agree with Dave that a

Re: Am I in the right track ?
Hi Dave, 1- I've upload the Kicad project as a zip file. 2- I also upload a PDF showing this part of the schematic and layout with different zoom levels in case you can't download or open the Kicad

Re: New user (owner) of Nano VNA
Howard, I used the SMA to SMA jumper cables which came with the Nano VNA and calibrated using the open, short and load connectors ( https://youtu.be/qb38VI-9tV0). Then I used an SMA to SO239 adapter

Re: New user (owner) of Nano VNA
Well, simply put: First, do an OSL calibration for the range you want to use, and store it in one of the memories. Then select Display > S11 > SWR. It should then display the SWR of whatever is

Re: New user (owner) of Nano VNA
Welcome to the group! The archives of this group contain much good information including videos and a guide for the VNAs for DUMMIES. Those resources should get you going. Dave -

New user (owner) of Nano VNA
Hey guys just got a nano VNA. it is a "seesii, nano VNA-H. I need some help in setting it up to see the SWR on some antennas. I have gone through the various manuals and the one that came with it,

Re: Am I in the right track ?
1- Would you recommend to clean all 3 elements of the matching network, as I don't know which component will go where ? Can you send me a schematic of the matching network? Possibly I can figure it

Re: What we can do more with TinySA ultra
Yes. The TINYSA is highly useful for frequency domain measurements. As well, the NANOVNA is equally useful for impedance domain measurements. As well, an o'scope is equally useful for time and

Re: Tdr
The NanoVNA-F-V2 has a convenient TDR function: It has its own menu choice. Just requires settings dependent on cable speed factor and short/long cable. Quite intuitive. Firmware 0.5.4 handles
