Hantek - Tekway - DSO hack - get 200MHz bw for free

[tinhead]

By ugrading sw, the problem is solved

so you upgraded to latest fw from the website (2.06.3_120808.0) and the 0x2 error is solved?
Good to know. Still, let's hope Hantek tell us the original reason.

@tinhead: I was  sent dst1kb_2.06.3_15062b_fact(120808.2).up file. If anyone needs it  I can upload somewhere. After updating, self calibration is OK.

[Jane]

Can anyone explain why I receive different values when measuring frequency?
Please see the picture.
Why is the difference of the frequency on the bottom line( which is correct) and the frequency on the measuring menu( which is incorrect) ?
Thanks

You are looking some kind of low freq alias.

Change Horizontal setting to around 20ns/div or somethink like this.
Still trigger counter (bottom of display) may give different (more accurate) freq than mesuring from displayed cycle.
Trigger counter is real counter.

Jane,

these DSOs have hardware frequency counter integrated - the bottom status line is showing the frequency from that counter.
The measure menu is however calculating the frequency from the waveform data, so far everything ok.
In some special case you might see difference between both values.

In your special case the measure menu frequency is such low because of undersampling - tis is here a clear aliasing effect.

Check
http://en.wikipedia.org/wiki/Undersampling
http://en.wikipedia.org/wiki/Aliasing

Without hardware frequency counter you would be lost, here you can easy recognize that something wrong
with sampling rate because of the (almost) always perfect hardware frequncy counter results.

[Jane]

Thank you for help.
When I changed Horizontal setting it works very good. But I have another problem/question.

I compared that hacked DSO5262 with the unhacked DSO5262.
And trigger counter( on bottom status)  shows about 199 Mhz measuring frequency with both DSO5262.
Is that normal?
How can I test then the hacking was successful?
Thanks

Jane,

the hack have no influence on counter, it works anyway up to 400+MHz.

How can I test then the hacking was successful?

if you can set horizontal to 2ns/DIV then the hack was successful.

@tinhead:Thanks for the reply.
Please check th e  blue arrow in  the enclosed picture if I understand well.

Could you upload the .2 firmware? The hantek site still provides the .0 firmware. Thanks.

[Jane]

The file is too big.It does not allowed to upload here.send me a location where I should upload

[tinhead]

The file is too big.

use winrar or winzip and split files or upload to a file hoster like e.g. hotfile.com

i've posted here small review of Tekway newest MSO

https://www.eevblog.com/forum/product-reviews-photos-and-discussion/mixed-signal-oscilloscope-from-tekway/

this is in principle nothing else than DSO like from this thread (must be hw1007 version) with extra addon PCB
and special firmware to allow MSO/LA!

The very cool thing is, everybody having Tekway DSO1062B, 1102B, 1202B, or Hantek DSO5062B, DSO5102B, DSO5202B
or Voltcraft DSO-3062C can pimp such DSO to MSO ... all you need it such extra PCB and firmware, and the good part
is, i spoke with Tekway and they will provide me all we need!

[rapsac]

I just noticed that conrad.nl has the VOLTCRAFT DSO-3062C (art. no. 122464) back in stock for 299€. I just ordered one and registered on this forum as it is THE place for the hanteks
conrad.de has it in stock also.


edit: sold out already.

@ Tinhead

I'm also interested in the MSO/LA but I checked my DSO and it's a HW1007 board but the PCB header socket (2mm) to connect the LA board is not installed.

Can I solder one myself ? Did I have to add something else to my DSO ?

Thanks,

Bernard

I will deliver all the necessary small parts. This means also that you will get :
- 1.27mm pin header
- 2 screews
- distance holder
- 5cm flat cable with 20pin IDC plug (to connect DB25 socket to LA/MSO PCB)
- DB25 socket
- DB25 header

You will not get any test cables, but they are really cheap on ebay 251150864536

All you will have to do is to:
- backup firmware (over USB flash drive with backup tool)
- remove sticker (front panel near USB) to expose the hole for DB25 socket. Every hw1007 have such hole.
- solder cable to DB25 socket (the IDT20 cable which will be pluged into LA PCB)
- mount this DB25 socket to front panel. I think there are already holes in the shielding, when you remove the sticker
  you will see immediately if there is any drill work necessary.
- solder the 1.27mm pitch header to DSO PCB
- mount the LA PCB to DSO PCB
- connect the IDT20 cable (from DB25) to LA
- reconnect all other DSO cables, so you can boot DSO.

Boot DSO and install new firmware. You will need for this UART<->PC connection and deatiled description how to
do this. I will get special crafted firmware (actually complette dump), this must be complettly restored to DSO
overwriting the old version. The biggest advantage : you will have newer Linux version, which is anyway necessary to
get network working. In Germany i'm offering "instalaltion service", so everybody who don't wish to play with
UART/USB to install firmware or solder cables/header can get this step done by me (for a small fee).

So as long you have :
- screwdriver
- solder station
- UART<->USB adapter cable
- max 2GB USB flash drive
it's not so much to do.

Hello tinhad,
Firstly, i wanna thank you for all the research in these scopes (firmware cracks/fixes, hardware schematics, troubleshooting, etc).
I study the hw schematics, because i am working on a DSO project on my own, and i use the schematics from HanTekway as documentation reference.
May i ask if you can upload the Altium Designer project (schematics)?

Best regards,
MEGABLINK

[Crenwick]

Thanks for the information,

I will send you a PM

Crap, my hw version is below hw1007 as I have a less dense expansion connection.

Is there a way to get this working on the older hw versions, and if not, why not?

Thanks.

Hello eevblog forum,

I finally bought a hantek dso5102b myself, primarily because of the great research done by tinhead and others. Big thanks to all contributers!
A few people mentioned WiFi dongles, and I really liked that idea, so I got a 10€ one from amazon. It has a realtek chipset, and they provide linux sources for the driver. They claim it only works from kernel 2.6.18+ but it compiles just fine for the hantek kernel. It took a while, but i managed to compile all the little programs for a wifi connection. Now my scope logs into my wifi automatically and gets its IP via DHCP.

The attached zip contains these files:

iwconfig, iwlist, iwXXXX	Wireless tools (http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html)
wpa_supplicant	Handles wireless network encryption WPA/WPA2
ifplugd	Checks for the adapter and runs a script when plugged in/out
8192cu.ko	Driver for realtek 8192 / 8188 chipset + different versions (syslog off, powersaving off)

+scripts and the network config file (/etc/wpa.conf)
+modified /etc/init.d/rcS, to load driver, telnet, inetd, and ifplugd

If you have a different dongle than the _{EDIMAX EW-7811UN} you might need to compile your own kernel module, but as long as it has a realtek chipset, there should be no problems.


@tinhead
Is there any chance of getting network support for the DSO-app on the bench models?
I tried to activate it by writing the [net]1 to the EEPROM, but I couldn't connect with ttscope or dreisiebners' dso-tool.
Taking a screenshot wirelessly seems like a very neat feature to me, so already tried to grab it directly from the framebuffer, but /dev/fb0 seems to be unused.

How will the MSO/LA modification affect the future  firmware upgrade path for the DSO5000?

I suppose you will have to follow the MSO path

Did anyone try to hack DSO5102BM?
I bought DSO5102BM few days ago only and wanted to hack it.
 But I noticed it uses a different software.
E.g. I need not use
 killall dsod command
to enter console and also  booting is different.
I were not able to change logo and not sure if the hack was really successful.
It shows DSO5202B( as I wanted) but not sure if it also works as DSO5202B.

Besides when it starts booting it shows
