I do not know.

Hi there,
Today I updated my 1000X with the BUD file. See photo 1
All licenses are active now, but the bandwidth remains 50Mhz.
Am I missing something?
Thanks in advance!
Mathieu

Hi, you can see it also says BW20, which is the 200MHz option, i believe. have you checked the timebase? with that firmware it should get to 2ns/, which is only available when unlocked to 200MHz if i'm not wrong. I may be remembering wrong, but i think there were some components that needed to be added or removed from the edu version to fully unlock the hardware to 200MHz, but that doesn't change what the software unlock does.

This option requires hardware upgrade in the front end channels. Information is in this thread.

pa3hfu · « **Reply #954 on:** February 24, 2023, 07:19:37 pm »

Ok. I thought that hardware-mod was not necessary anymore.
When I load the Fercsa hack, the bandwidth becomes 70 Mhz!
Timebase = 5ns

Bud · « **Reply #955 on:** February 24, 2023, 09:23:00 pm »

For 70 MHz, not for 200MHz. The IC used in EDUX front end amplifier is not capable of 200MHz.

Hello!
For BW increase o EDU you must change the resistor on main board (original is 01B and you must change by 01C when you want to use id 24 with generator etc). After this action without changed FW the BW will go to 70MHz from 50MHz.

My story with EDUX type:
I have tried the upgrade, but before this I was having few days active trial licences because I made some work with SPI bus and I needed to analyze it.
In the first time I have changed the resistor on the board. Unit went from 50MHz to 70MHz, activate generator and more memory. See the attached photo.

After change FW (Bud1M 1000x series v. 1.2) uploaded by Anthocyanina, the BW went to 200MHz, but only few options were active, BUT serial decoding, sample rate etc. were deactivated! I have tried to change FW back to original and bus decoding was again activated (trial). I wanted to clear it. It was possible by changing year in clock one year back and switch off/on the unit. Then were only options by HW modify active (no bus decoding etc).
Now I have applied Bud1M 1000x series v. 1.2 again. After done, all options are now activated (incl. bus decoding, sample rate, BW 200MHz...).
So when you have trial licences active, on the first time you must clear them or some interaction with hacked FW will stand!

There is no wave generator on 1002A, the board is not populated with generator parts, you have to solder the parts.

pa3hfu · « **Reply #958 on:** February 28, 2023, 07:19:53 am »

Is this the resistor 'mod' I have to do on my EDUX1002A?
Add 15K on the left and add 10ohm on the right?

pa3hfu · « **Reply #959 on:** February 28, 2023, 08:36:15 pm »

To TK:

You wrote: "The information you see in the screen is not changed, but the scope will boot into the mode set by the resistors. You will see features that are only enabled on the DSOX, even when the information says EDUX...
The HW mod is required as the EDUX comes limited to 50MHz and no ext digital input on the additional BNC. By adding the missing components and changing those that are different, you are enabling the HW to be ready to the soft configuration that is liberated by the FERCSA Hack."

Can you confirm that the correct resistors(mod) for my EDUX1002 are mentioned in the picture I uploaded?
Thanks!

To BUD.

Pse can you answer my question? See picture above.
Thanks!

Thanks JDubU!

Unfortunately, the values of the 4 resistors are not easy to read.
If the picture I posted above is correct, I know which 2 resistors I need to solder in parallel on my EDUX1002A.

JDubU · « **Reply #963 on:** March 01, 2023, 03:33:43 pm »

Your picture above is not correct.

For DSOX1102A (no wavegen):

10K (01C) 12.1K (09C)

6.49k (79B) 4.64k (65B)

If you prefer to use parallel resistors, you can use this calculator:

Here is a calculator for the (EIA-96) resistor codes:

Thanks!
SMD 79b and 65B cannot be found on the internet. Even Aliexpress is sold out...
So parallel mounting seems to be the only option.

JDubU · « **Reply #965 on:** March 01, 2023, 05:58:21 pm »

Interesting... They are readily available in the US from both Mouser and Digikey:

On my EDUX1002A 3 resistors are the same. I only have to solder the 79B.
I ordered at Mouser.nl
Many thanks!

pa3hfu · « **Reply #967 on:** March 05, 2023, 11:12:55 am »

I made a switch to enable EDUX or DSOX mode.
When I want to do a user calibrate, the scope can do that in EDUX mode.

HighVoltage · « **Reply #969 on:** May 26, 2023, 10:57:10 am »

Does anyone know, if the BW can be software updated on a DSOX1202A ?

TScarlet · « **Reply #970 on:** June 15, 2023, 08:36:35 am »

Hello everyone .I have got a DSOX1102G and installed the "Hacked" firmware，now I have got a full bandwith DSOX1102G with all function enabled,but I loss my model and SN. In "About This Scope" Page,It show Model:Unset,Serial Number : UnSet ,Bandwidth :200M。What is wrong? How can I get my Model and SN back?

that's a weird one, try installing the official firmware and see if that restores the serial number?

Thx,I have tried,but still get UnSet Model and UnSet SN
