Thanks!

The frustration weed is sprouting. The new card was booting and going through the setup/upgrade stuff, and then would not boot at all, hung at the Welcome screen with mounting... text below.

Test Equipment / Re: SDS800X HD Bug Reports + Firmware

Another issue: i am pretty sure i could use the b-word:
The setting of the trigger type edge influences the qualified trigger. In the first part of the video the trigger is not exactly stable, only if the slope of edge trigger is changed, the qualified triggers works without issues.

That is a strange one... Did you check the details of the qualified trigger settings before and after the edge trigger change? I.e. did anything get changed in the displayed settings for the qualified trigger, as a side effect of the change you made to the edge trigger?

Repair / Re: QPX600DP - "Incorrect Configuration" (Updated with bounty offer)

« Last post by CLOLUS on Today at 09:04:27 pm »

Hi,

I have a QPX600D with the same problem of message "Incorrect Configuration". I find on the web the shematic diagram of this power supply : https://everist.org/NobLog/pics/20151112/sch_ps/HP_54120B_power_supply.htm

The fuse 15AT was broken and I changed two diode in short circuit (US1J 600V 1A) ref D36 D37. The power supply is on now without problem with the Fuse, but i have this message of "Incorrect configuration".
I don't know how to solve this problem. I checked the documentation without success...

Is just measuring the cell voltage out of the question?  From the curves, it looks like a 2.8V reading tells you it's almost out of juice.

I would imagine at such low currents you are essentially measuring no-load voltage which doesn't tell you much about remaining capacity.

General Technical Chat / Re: $20,000 dollars of software or licences on a thumbdrive ?

A dead license dongle can usually be replaced for a small fee once you return the dead one.
But a lost dongle often results in having to fork out the full cost of a new license (or use insurance).

Mainly because if that was not the case, you could give it to a friend, say you lost it and get a cheap replacement and your friend could use the software for free as long as they stay offline so the lost dongle S/N never gets deactivate in an update.

I'm in a bit of a doubt about this. Because if you have a dongle, that allows you to use a software that you are not licensed, you are still breaking the license agreement. So I don't think it would fly with any serious court that you have to buy a new license. Plus software like Orcad needed a license file and a dongle, and it was computer tied, and PITA to get working, with calls to the support department. I guess they will of course try to sell you a new license, but I don't think it's legally acceptable.

In court  maybe you'd be right, since the dongle has no real function. But doesn't stop companies from having the policies:
https://softron.zendesk.com/hc/en-us/articles/207695807-Policy-for-Lost-or-Stolen-dongles-Are-dongles-guaranteed
https://www.ecadstar.com/en/lost-license-files-dongles/ (they'll replace it for free IF you are paying maintenance, if not cough up the full price)
https://www.laserscanningforum.com/forum/viewtopic.php?t=17205

Just gives off the vibe of a unfriendly company, if using a dongle in 2024 wasn't bad enough already.

Surprisingly Altium would re-instate old licenses completely for free, even if you don't have maintenance.

Projects, Designs, and Technical Stuff / Re: "practically smallest" debug connector on tiny pcb

« Last post by ataradov on Today at 09:01:01 pm »

First of all, reduce the number of pins. In addition to the SWD+GND you may need VCC for powering the debugger buffers, and may be reset. So, at most you need 5 pins.

And then the smallest connector is just 0.05" though hole header. It can be populated with an actual connector or wires soldered to a more useful connector. It can also be used as test points for mass production.

For the same small number of contacts, FPC connectors end up being bigger, since they need mechanical pads as well.

General Technical Chat / product design and anonimous data collection

« Last post by strawberry on Today at 08:58:49 pm »

what happen if some company buy data from google ... and use data to find innovative product ideas
when companies can make profile of some person by buying peaces of data..

similarly as amazon does with its sellers
facebook hold all rights to all data appeared on website
dont know about emails legal stuff
but basically someone sells off its innovation for 1EUR

not legal expert nor read all license agreements or terms of use

Test Equipment / Re: SDS800X HD - Issue disscusions - is it me, or the scope?

« Last post by ebastler on Today at 08:57:28 pm »

I have indeed not used the mask editor at all yet. Could you describe what seems to be wrong? Ideally in a simple step-by-step sequence which we can try and reproduce.

I saved settings before, and after restart for the trigger settings lost issue. Maybe some other settings get lost also?
