Can you first do a level calibration and then run the test again?
If the level calibration fails, post a photo of the fail message
Make sure the test on the screen is readable

yes - connect sma cable for both hi-lo ports - this is the latest test i made ..

Here's the link I was referring to:?

Note, it's a lot of reading!?

Thanks all for the advice. The?Siglent SDS 1104-XE sounds interesting. I can’t find the thread referred to in the EEVBLOG forum; their search function is broken and doesn’t recognize a correct CAPTCHA entry. I guess I can try a general Google search for that. ?

the PICO machines ate also interesting as I have a spare Raspberry Pi i could set up for use with it, but even so they ate more expensive.?

Did you connect the CAL and RF connectors with a short coax?

hi guys - having problem during self-test "Test 3" failed and stops from there

In practice, recently I've found a battery operated scope more useful than an bench model. Something like:




or the slightly larger mode, currently on sale:




For an even more compact size:

Need use DFU File Manager util from DfuSE DEMO



Click Multi BIN button


Select bin file and set address 0x08000000, click Add to List


Click Ok


Click Generate and set filename



Now you can use this DFU

NanoVNA-App and TinySA-App allow load bin files, so no need convert it

You might want to consider the SDS 1104-XE.? It's the 4 channel 100MHz version of the 1202-XE.? They can be "upgraded", via firmware, to 200MHz.? There is a very long post on this over at EEVBlog on the Test Equipment Forum.? To my knowledge, no one has been able to find any differences between the "upgraded" 100MHz and the 200MHz model after the firmware was updated.?? In other words, there appear to be no hardware changes between the two models, only firmware.? Note: This is not an official upgrade, someone figured out how to do it and shared the info.? I've done it to mine and have had no problems.? Whether or not it is still possible to do is up to the reader to ascertain.

NB - I don't know if Siglent has done anything to prevent the installation of the firmware in the latest iterations of the 1104-XE.? The above referenced post should address that.

OK, it was new for me that DFUSe can write bin-files. Than it's clear. Thanks.

Flash dumped firmware as you made firmware update (use CPU soft: TinySA-App or NanoVNA-App or DFUSe-Demo)

Main problem in update - firmware can`t self overwrite, so update fw from flash in current device not implemented.

But how the device can be restored? There is only a export function. No import.

This allow dump all flash data from CPU
This allow restore device later (include all settings and stored properties)

This function in Expert settings menu (not for all users)

Can one of you list the commands I need to give to do this?
Merging the V4.3 branch with main is not something I want to do so it should be something like a rename????

Erik,
There are two possible options I just am thinking of.

1. Rename "V4.3" to "main" locally and remotely.
? ? Set "main" as default on GitHub (instead of currently "master").
? ? Work on "main". Do not touch "master" anymore (or remove it).

2. Rebase "master" with "V4.3", i.e. apply all changes made to "V4.3" from beginning (when you branched "V4.3" from "master") 'til now.
? ? Work on the (now up-to-date "master"), leave V4.3 untouched (or remove it).

I think 1. is easier and less error prone.
I'm currently on a business trip and will review both in a fresh fork on my system when I get back on Sunday.
Then I'll distribute the step-by-step instructions.

I think the function to export the firmware is very new. What's the sense of it? Are there the settings inclued? How I can restore it?

Now I had time to try it. Thanks, now the touch calibration is perfect.

Thanks for the details. The gap size is critical to getting a good match.

I'm still looking for a good solution for larger discones, most insulators I've used get wobbly and break if the disc needs to be larger than 15cm or so.

I suspect I need to design something for 3d printing...

Thanks again...
