Hantek DSO5072P thread - Not the bandwidth hack thread
« on: September 30, 2015, 11:42:53 AM »
Im starting a new thread to document some of the stuff I've done with the 5072P.  Please do not reply with bandwidth hack related info or issues.  There is another thread for that.

Just to start off

The unit was received yesterday and had the firmware upgraded to the latest rev 3.40.0(150907)
Hardware model is 1000xffff8108



I wasnt initially aware of the FFT, however I was pleasantly surprised and after a calibration run and probe setup I used the reference square wave in FFT mode to see how it looked on the spectrum.  The reference waveform is 1KHZ





This evening I used my TSG AM signal generator to see how I could dial in a nice representation. 




I also finally had the opportunity to see if the issue i'd noticed on my Feeltech FY3200S signal generator with my analogue scope existed on the new scope.  Sure enough... it was the sig-gen

I should point out in fairness, that had I actually hooked my scope leads directly to the output of the generator, then the shape of the squarewave improved at low frequency.

Just FYI, the FY3200S is only specified up to 6Mhz for everything except sine. It's only sine that is 24Mhz (or whatever, depending on model). See attached screenshot. I also attached the PDF of the manual in case you don't have it.

Today I did a replication of Martin Lortons capacitor measurement setup.....





Here is the second test with an orange drop .1uf capacitor.  Video to follow

You Sir, are correct.   I should have checked the specs.   That being said however........

This capture of 5.6MHZ looks pretty shitty as well

What's your probe setup like? I think your ringing might be coming from that rather than the sig gen.

Mine is jittery and a bit rounded, but it doesn't look nearly as bad as yours. Attached is screenshot; setup is RG58 coax from gen to scope with 50ohm terminator on a T piece (I don't have a straight through terminator) at the scope.

Great, glad that's sorted. If you want me to do anything for comparison let me know.

One thing I noticed, it looks like you have the 20Mhz bandwidth limit turned on for channel 1 on all your screenshots. You will be filtering out some of the harmonics, which will round things off a bit. It won't make a massive difference but it will be noticeable; how much will depend on whether your scope is still 70Mhz or not.

Sorry for derailing the thread a bit. How are you finding the scope?

No you're not derailing....   This is kinda what the thread is all about.... 


Id expect naturally, that after I make measurements on the 5072P that folks would come back with findings for comparison.

As for the scope, I love it..... only a few small complaints that are very minor

Incidentally, I've made yet another movie.....

I decided to put a crystal oscillator in series with the scope and a freq generator to see what happens on FFT
Heres what I got

Just had a 5072P delivered, and I am assuming the firmware is dated Year/Month/Day, if so it seems that mine has more recent firmware than that available on the website.  At date of posting the website gives 151906, while I have 151009.

Year/Day/Month     June 15 2015   and you have Sept 10 2015,   no doubt the website can use an update

Hi!
This is my first post in this forum, I hope it is very useful!
I have just purchased a DSO5072P and have a couple of issues:

- First of all, some keys don't operate unless you press them really hard. But, for example, the HELP key doesn't respond no matter how hard you press it.
- The filtering function under Utility doesn't work: you can set up the filters (lowpass, highpass, bandpass, etc.) and adjust them so that they should clearly affect the displayed signal, but no changes at all.

My version is 3.40.0 (151009.0)

Do you have any advices about this?

Thanks!

It seems as though these models are being phased out for newer ones, ive decided to go ahead and open mine up to 200MHZ to accommodate the 2 metre band.


Ive made a movie covering this process on my scope and published it in the main thread but here it is

Hi,

Just bought one (5072P), 230Eur shipped from Germany from aliexpress, no mods yet, just playing around.
Anyone tried to run the firmware with qemu?

As you have made with succes you hack to 200 Mhz, and as i also get problem with doing a back up i put below my first thread expalining the priblem i have.
perhaps you can give me a little help to resobe the backup problem :

***************
  Hello, I am new on your forum and send all of you  my "hello", my English is not so good as yours so please be patient with my questions.
I received a week ago an Hantek scope DSO5072P with the following information:
Version logs: 3.40.0 (170209.0)
Hardware version: 1010xffff8108
S/N: T1G/035 65xx
As there was a new version of firmware dso5072p20170318. up I decide to make first a backup, like to explained by tinhead without success, by using tool_P_models.zip.
I have tried to rename the file with the same name as the firmware update and I only get the error oXfe message.

When using the original name of the backup file I have the message there are no file for firmware update, after renaming the update file, it  seam to work, but after few seconds message "the file has not the right format" is displayed.
Finally,i do the firmware update witch works and only the version log display seam to be changed with a display:  3.40.0(170318.0)
As my knowledge, in Linux  is basic can any body body from the forum help me to progress and explain me how to do backup via USB to word converter or perhaps I miss Something in the software backup procedure. Perhaps it is posible to do that via Windows.
I will appreciate your help and sorry again for my English
******************
Many thanks in advance.
