Test Equipment / Re: POST Hacking Rigol MSO5000 - POST HACKING TUTORIAL - DEEP DIVE

« Last post by BRZ.tech on Today at 02:00:52 pm »

Hi,
Dear @BTO,
To explain better, and you understand:
You stated that:
“Anyway, it all works, I think you just didn't use the IMPORT option”
Check my msg #62, in (item #4) that I used the (IMPORT) function to bring the IMGs saved in Drive (C) to a position in the Table (Refx).

The central issue is that you can IMPORT (10 IMGs) saved in Drive (C), and load them into Memory positions (Ref1 -> Ref10). But you can't use it (ONE AT A TIME). Check out:
(Press -> CLEAR) and try running just one IMG saved in the (Ref Table).

As for your message #65, you understood my question regarding SlewRate measurement, and forwarded it to the solution. It's great that you were able to open this solution channel with the Rigol Engineer.

I have other similar UI questions, in the Bode Plote and FFT functions. I will produce a coherent text, and post it here for you and other colleagues, to see if there is any viable solution.
Much obliged.

Microcontrollers / Powering an STM32F103C8T6 With 12 Volts?

« Last post by AlwaysAbia on Today at 01:56:52 pm »

Microcontroller beginner here.

I'm building a project where the main power supply is a 12 Volt Power Supply. The project contains an stm32 in it, so I was wondering if there was a way to power the MCU directly using 12Volts without having to use a step down converter.

Thanks in advance.

Altium Designer / eye diagrams in altium 2024

« Last post by nomar123 on Today at 01:56:45 pm »

Is there any way to generate an eye diagram in the signal integrity toolkit in Altium 24? Found some old altium forum posts that say there is no eye capability but those were from several years ago. Has altium added any way to generate an eye diagram from layout traces??

An original key for the ETC in my possession is: 066379365018881348971792051684 relating to the K140 option. In the results of main.c this type of key does not appear but only 10 numbers. How to solve the problem for the K240 always with 30 numbers?

Beginners / Re: what an oscilloscope recommended for a woman passionate about electronics?

« Last post by CharlotteSwiss on Today at 01:51:52 pm »

In the channel settings of my Siglent, I see that there is also a possible limitation of the band to 20Mhz. What would be the usefulness of this function? Since I almost only measure signals below 20 MHz, should I always leave the 20 MHz band limit activated? Any help? Thank you

Test Equipment / Re: Hacking the Rigol MSO5000 - Dr Mefisto Licensing Method

I think firewall, access, etc. things have nothing to do with it. The script reads the contents of memory and tries to change it. But the script cannot do this, since it does not receive what it expects.
I have unlocked some debugging information, but it may only be useful to the developer of this script.
That is, the stage of transferring the changed information (key) to the oscilloscope does not occur, since a new key has not been created, access is not needed here.

Repair / Re: Capacitor has different readings if stored upside down

Also, in one direction gravity is trying to squash the plates closer together, but 90deg from that it is not.

However the affect of this I would expected to be very very small. Probably quite measurable but not with a typical accuracy DMM.

Test Equipment / Re: DH-801 Electronic load

The one I bought is without the RS232, since KeLian Electrical Instruments Store only had that one. In the manual there is nothing mentioned about SCPI, only a mention of RS232 is optional. My hope is that the unit can be easily fitted with a TTL to USB serial converter but that I will see after opening it.

Test Equipment / Re: Portable Oscilloscopes List (cheap)

f you can provide more accurate values for them I will happily update the list.

I did and you did not update the list.

Also, I ran a 3-part series on the Zeeweii DSO3D12 and it does indeed have a analog BW of 120, not 82 as you list.  Not worth posting those videos though as I see you will not take them as evidence.  Not sure why.
