For low frequencies (down to DC) I bought a Digilent Analog Discovery with the impedance Analyzer module for S11. No extra hardware is required for transmission measurements though some adapters they

G'day Ruslan. I doubt that this would be practicable. Tom DG8SAQ recently provided very-low-frequency capability for the VNWA; /g/VNWA/message/22207 If your budget permits, you could

hello is it possible to lower the input frequency range of n2pk? for example if one not using toroid transformers on the output of DDS?

Hi Kurt, Thanks for checking it! I have made all the changes you mentioned, and also added a link to your document repo, since that's an amazing resource. I have downloaded it and am exploring it.

Hi Shabaz Excellent document, congratulations, very well written. I think you could add to the line "The VNA indicated in the datasheet happens to use two-way delay values, so the values above need to

Hi Kurt, Ah, got it. I now understand that male open text. I've written a short guide on how to use the kit with any VNA, it is here:

Hi Shabaz Well spotted as the datasheet mention "electrical Length" and the present VNWA software described it correctly as "mechanical length" It is probably time for an update of the specification

Hi Kurt, Thank you, that's all clear and makes sense, perfect! For newcomers, they will find it confusing that the screenshot in the datasheet mentions "electrical length" yet gives values which are

Hi Kurt, Thanks for this. I've looked through the docs, and had the following questions: 1. In "Basic Transmission line" doc, I see the text: Similar techniques are used for the female short which is

Hi Shabaz I am the author of the datasheet you link to, and I can give the answers to all your questions. I insert my responses below. Kind regards Kurt -----Oprindelig meddelelse----- Fra:

Hi, I've purchased a SDR-Kits Female Calibration Kit of Rosenberger parts, it's intended for DG8SAQ VNWA, but I don't have that, I intend to use it with N2PK VNA, and R&S FPC1500 VNA. I had a

G'day Juan. It's Dave G4UGM that you want, I think. He has a website so should be contactable there. You will not require any advice on the construction; you have, I'm sure, built more of these than

Hello Kerry, I am interested in the N2PK boards, could you please indicate the price? I am located in Hampton UK. Thanks. Kind Regards, Juan J De Onate M0WWA jjdeonate@...

A generous offer, Dave. I suppose that most here already have an N2PK VNA, although some may have envious friends. :) The QRP folk are great builders; someone there may be interested;

Folks , I have a Rev 5.2 board and return loss bridge board, unpopulated. Willing to ship for postage costs if anyone can use them. Dave G4UGM

Could it be a configuration setting? FWIW these are the settings I used in myVNA (unfortunately it keeps license-locking-up on me, it always thinks my laptop hardware has changed, so I'm struggling to

I have a 1.020K .01% resistor and when I try to measure it with RFIV calibrated with 50ohms it seems to be all over the place. I have to keep working with it I guess. And I need to find the darn top

If this helps anyone, here is the construction of my RF-IV probe: http://blog.kotarak.net/2009/11/n2pk-vna-rf-iv-sensor.html http://blog.kotarak.net/2009/10/n2pk-vna-rf-iv-sensor-pcb.html 73 AE1S
