OK lets run this off the cliff. If you have a propensity to build your own cables I would suggest LMR195 ultraflex cable. This is the same size and very similar characteristics as RG142but is much

Get some semi rigid cables, the shield is soldered to the connector shell so it won't come off any time soon. RG402 is the thicker and stiffer variant, RG405 is the thinner, more flexible one. I got

VNA cables need to be considered as consumables, they will eventually break or the connectors become worn. There are many sources of flexible cables online, Amazon and EBay have many. There is nothing

Save the broken cable. Maybe you can use it when building a test fixture or similar. *Clyde K. Spencer* [email protected]> wrote:

I would no longer trust that cable. You can get a pair of these cables from Amazon.com or other sources. The screen shot below is from Amazon.com [image: image.png] *Clyde K. Spencer*

This past weekend, I accidentally pulled the SMA connector off one of the thin coaxial cables. The outer threaded portion came off, but the center pinwas still attached. The cable checks out, or at

Yes, it was also something for the final DC block from the 6146 plate voltage to work against. Dave - W?LEV g3vgz-groups.io@...> wrote: -- *Dave - W?LEV* *Just Let Darwin Work*

Hi Vladimir, Larry, and Group: Thanks so much for your advice. The references that you sent basically go in the direction of using the Cypress driver. I tried this, but to no avail - also get similar

Search the group for "traps". Several posts on this topic. Roger

I wondered if anyone has measured Mosley traps with the NanoVNA? I have one on order. Currently I used a MFJ259c to try to get some results. I took the trap apart and put a 50 pica farad in series to

Dear Vladimir, Thank you for your suggestion. I will look into it today. 73 Ray 4X1RB From the home of Prof. Emeritus Raymond (Reuven) Boxman School of Electrical Engineering Tel Aviv University Cell:

I have a lot of respect for the gentleman in question. He must be independently wealthy as he seemingly tests every multimeter in existence and then posts the results of his testing for FREE. I have

Hi DiSlord, numbering instead of random "RTC" naming is a great idea, but I understand it may not be easy to implement, need to add reading files and "logic". An updated fw v1.0.69 from 31.7 with

Thanks for the suggestion! I will investigate it later today.... Ray From the home of Prof. Emeritus Raymond (Reuven) Boxman School of Electrical Engineering Tel Aviv University Cell: ???? +972

Just wondering if you hit the parts you're testing with a heat gun and/or freezing spray to see how how well the consumer level parts react.

DiSlord, For the V2 Plus units with no RTC, can the SDcard filenames be read and the next file saved has its last character incremented by one? This assumes a fully numeric filename so there are no

This is the code I use to find the PLL min/max limits, but any desired code will do .. uint32_t si5351a_pllLocked(const uint8_t pll, const uint32_t timeout_us) { uint8_t pll_bit; uint32_t

I've been using the Si5351 in another project and decided to test the chip at boot-up to find each individual chips (Si5351) possible PLL frequency range rather than having the 300MHz parameter be
