Really big kudos to Tinhead
out of stock till 20 april
which worries me I am not sure which version FW we get if we buy one,
I don’t think Voltcraft will make a custom FW just for this scope but you never know.
For those using Linux, I did a quick Python script (using PyUSB >= 1.0) which lets you upgrade the scope from 60MHz to 200MHz (or other variants if you edit the script, see comments).
Migtyhzen, I got 2 scopes one 20 MHz dual channel and a 100 MHz dual channel with 4kb memory, but I can’t resist the price on this one right now, I think I just need a new toy and a nice digital scope with all modern capabilities. Well I got one more day to think about it and it looks like I am going to order one.
.... Care to share some details?
Tinhead! Kudos!
Now, there's a bug in the handheld I have fo
here: http://www.biasedlogic.com/index.php/hantek-dso1062b-dso1102b-dso1202b-vs-5gss-lecroy-waverunner/ I have put a few observations about triggering on tricky signals from LeCroy's "demo generator". There's also a comparison of 33MHz "square" wave image from the Hantek and from a 600MHz 5GS/s LeCroy Xi-series (Xi 660 I think).

indeed, i can confirm the first bug (actually only the first part, i ddin't saw any trash on my display)
on 111212 firmware version. Btw, what is loaded on your handheld?
Not sure about second bug, sometimes it looks like what you said but sometimes it seems to be
just a bit delayed post-processing.
I did compared both handheld and bench versions, from what i can saw handheld
is having bit less jitter (pcb routing and new fpga design) and bit higher bw.
With active probes (and the /tst file hack to set bw filter higher) i got 250MHz -3db bw,
more than sufficient for 1GSs DSO.
"PP008 price", yeah, this is "the dark side of cheap scopes", a good set of probes costs
more than such DSO itself.

What's your mother tongue?
I have populated the DM9000EP along with a LF8505 magnetics (picked one from an old network card) and in the bootlog I see the driver picking it up. So far so good. I'm still missing a suitable jack, but I have ordered one that might fit, it just didn't arrive yet.
The scope menu shows network not supported, I believe this is configuration issue, do you have any details on this?
Is there any useful functionality available over the network interface BESIDES a console (which was reason enough for me to try the thing with a DM9000EP)?
Hello ,
I am new here and have an Voltcraft DSO upgraded to 200MHZ . All worked fine so far .
Now by looking at the Hantek home-page , I found an new Firmware 120224.0
Has anybody already experience with this version -repectivly what known bugs are fixed ?
Thanks for feedback in advance

Few hours ago , I checked the online store from Conrad ; SURPRISE ! It does show the Voltcraft DSO 3062C "Sold out "
As the original delivery dates were already changed in the past from 20 April to 20 May , I guess somebody has stopped this offer .

Guess they have figured out the real value of the offer
There are some other reasons why the Voltcraft DSO-3062C is no longer available
I started documenting my JTAG setup for the S3C2440 (basically I abused an old IDE cable and soldered directly to the PCB), and I also wrote a small OpenOCD config (which has been included upstream already).
http://randomprojects.org/wiki/Voltcraft_DSO-3062C#JTAG_.28for_Samsung_S3C2440.29
JTAG seems to work fine, I'm currently dumping the NAND flash chip contents via JTAG (takes quite a while though).
I've also started playing with Barebox (will also test U-Boot later) and buildroot (for rootfs and cross-toolchain). Building a Linux kernel and flashing my own rootfs will be the next step.
My UART setup is also documented here:
http://randomprojects.org/wiki/Voltcraft_DSO-3062C#UART_2
For this, I used a standard FTDI FT232R-3V3 cable and some custom-soldered mini-addons to allow for the cable being removed later (if I need it for another project).
Also, if anyone is interested in more PCB photos, UART bootlogs, lsmod/cpuinfo/mtdinfo/etc., waveform comparison before/after the 200MHz hack, and such stuff: I've put some more photos and info on the randomprojects.org wiki, and more detailed photos of individual PCB parts / chips will follow.
