Mike, and others, Eli got there before you asked! It's to be found at https://github.com/EliMattingly22/Simple_Impedance_Analyzer/blob/main/Impedance_Analyzer_V2_KiCAD/Impedance_Analyzer_V2.pdf. HTH,

Seems like you have all the info you need. Standard US fine thread screw would be a 1/4"-28. (coarse thread is 1/4"-20) I checked the binding posts on my Boonton 260A and the are 1/4"? fine thread.

Hello Eli, Thank you for sharing your work. I had a quick look at your design on Github but it turned out to be a very superficial look because the schematics are only in Kicad format. I know Kicad is

thanks Dave, I knew you make professional kits, but they are far too expensive for my poor wallet. :-( Claudio

Hi all, I have 2 Q meters, a Boonton 260A and a Marconi TF1245A, both restored and working nicely and beautiful instruments. The Boonton coils fit the Marconi but the reverse is not the case. I want

I eventually found a video distribution amp that did a good job, but the first one I used tried to do sync restoration, which made a pretty nasty mess of my 10MHz signal. Choose carefully and check

A standard (analogue) video distribution amplifier could be used to buffer your external 10MHz source. They are designed for 75Ω input and output impedance, have 10 isolated outputs and are designed

If you go by what HP's frequency counters expected/accepted, it's roughly a volt rms, perhaps within a factor of 2. Some go as high as 5V, but that's not what's required -- it's what's tolerated.

I'm fighting a problem with some signal generators and I thought this group might have some information I need. 1: For a "typical instrument" what level should the 10 MHz input be?? These SGs say

Below are my accuracy test plots-- of course take everything with a grain (or handful) of salt because I don't have a calibrated set of resistors/capacitors, and I'm still a student learning the

VNA calibration kits are available with both male and female connectors - my company sells them. https://www.kirkbymicrowave.co.uk/ Specifically an SMA kit.

I bought a couple of miniVNA and both came with a male SOL kit. now, whenever I want to measure a DUT, I need to use cables which are terminated with a male connector. to calibrate the set up I need

Hello, a small video explaining the process (and a suboptimal but working design for the HP 4262A) is here: https://www.youtube.com/watch?v=LAmc1_PtYAs Tam - - - - - With best regards Tam HANNA Enjoy

hello I have this one https://www.ascel-electronic.de/bausaetze/2/ae20204-hochpraezises-lc-meter Working for normal price. Not like profesional but for radioham are ok. bye matjaz

You've never heard of the Kelvin temperature scale ? or the 3rd law of thermodynamics ? Named for the? work of William Thomson, 1st Baron Kelvin. ?Ken G8BEQ

It's not so much that there is a clip named Kelvin, but that there's a thing called a Kelvin connection, in which you drive the DUT with one pair of wires, but sense voltage with a separate pair. This
