Hantek DSO3064 / 6074BE Scopes

Bob, I decided I couldn't live with the 6074 and returned it about a month ago. I since bought a Pico 2204a. I'm still learning but I plan on sticking with this scope until I need something more powerful. Thanks for your help on the Hantek. Mike

You're welcome! I'm sure everyone on this thread ( myself included ) would love to here some updates about how you find working with the Pico 2204a once you've learned your way around with it.

Can you reduce the sample rate of the scope? Almost looks like its over sampling the signal. The sample rate should be different than the bandwidth mhz settings.

Thanks Juergen.

Have you used the USB Autoscope? It looks interesting and price is not bad. I need to look further into it.

The first thing I learned is the Pico 2000 doesn't come loaded with all the probes the automotive scope has. So I needed to create custom probes for my HT-25 and both Hantek amp clamps. That was a problem until I found this video:

The only thing it lets you control is the buffer length, between 4k and 64k for a single channel. If you look at the bottom right hand of the display you can see what I think is the sampling rate. It is automatically set based on the time base chosen; for example at 20ms/div it's 12.50KSa, at 1ms/div 250.00KSa, 500us/div 500.00KSa.

I tried setting the bandwidth limiting which is supposed to ignore anything above 20Mhz, and that helped a little, but not much. On the trigger selection it lists, "The user can turn on “HF Rejection” to eliminate trigger higher-frequency (20M above)", so I'll try that when I have a chance, but I doubt it'll make any difference.

This things is either damaged in shipping, defective or just junk, I'm not sure.

That sucks. How can they create a lab scope and software package without a way for manually adjusting the sample rate? Stupid. Maybe in "settings" if there is such an option somewhere for an option that "auto selects" sample rate or other variables? I have just been using the Modis and Verus Pro which also doesn't allow for manually selecting sample rate though it does have the peak detect to up the sample rate to a preset figure. I am not sure how much sampling is too much for a given time base.

Ordered a 6074BE scope off ebay. I'm in a position where I needed one quick and can't get the pico yet. $215 plus I order a 20:1 attenuator and Fluke BNC to Banana adapters for my test leads / probes and amp clamp I currently have. I have a 1 channel scope that does not have a buffer so makes it hard to analyze after the fact. Move to a new job paying lots more money so i'm hoping in the near future took pick up a pico

I know there will be issues, maybe I can find some work around for some of the faults it has and help others with it too. I'll give you guys my little review after I use it this weekend on my fathers car.

Honestly, I didn't find the 6074BE from a day to day practical point of view to be any better than the 1008c, that's why I returned it. Hope you have good luck with it though.

Its not looking good for this scope.

I just tried getting secondary ignition waveforms 3 different ways and only 1 way was effective. Using the included secondary capacitive pickup the waveform shark fins some times and other times its a super noisy secondary waveform. I also tried an alligator clamp attached to the outside of the spark wire which works great on the Verus and the Modis, though not safe at all...this doesn't work on this hantek scope either. I get the same shark fin type of waveform. Grabbing primary voltage from the 2 wire coils on my car, I was able to get a nice clean secondary waveform.

I am not disappointed as much as I should be cause I know these scopes absolutely suck so my hopes were not high at all. I'll use it through the weekend, see if I can do any more with it.

Which one are you talking about, the 1008c or the 6974be? One issue is that they are susceptible to EMI so you need to position them away from the dizzy / coil and other wires as much as possible.

Hey Sailor,

Im curious about the 1008c. Have you scoped CAN signals with it? Also how many channels have you used at one time? I'm just curious if the 8ch scope bogs down when capturing multiple signals

I have not tried it with a CAN bus. I think I've used up to 4 channels at once. The thing is, that the way this scope works is that it streams all the captured data over USB, and the triggering is done in software on the computer side. The scopes internal buffer is 4k samples, and that is divided up between the active channels, and sample rate is determined by time / division. So what does that mean practically? In my experience, if I want to look at a crank and cam signal on a 200ms screen, no problem. If I turn on a third channel at that point the crank signal will go all wonky due to aliasing, since there isn't enough samples to go around. But drop the time base to say a 50ms screen, and the signals become clear again since you've got more samples per unit time at 50ms. So for example, on a 5ms screen I have no problem having primary, secondary and current ramp for an ignition signal on the screen at the same time.

Basically, it has it's limitations, but you can work around them. It could actually be a pretty great scope if it had decent software.

I also just ordered the 6074BE. It is for home/personal use, with maybe the occasional helping a friend. I am also not expecting very much, but at the same time it is more than I've ever had. At 50+ I am trying to acquire some of the tools/equipment I always wanted, even if just to try. I will follow this (and other) threads closely. Also, watching Eric, Ivan and Danner's videos has been eye opening to say the least. Almost information overload!


Thanks all!

Honestly, the software on the 6074BE is atrocious. I'd recommend sending it back and getting a Pico 2204A which is only $140.

thank you for your comment on hantek 6074 and the video you uploaded.
please inquiries
1- does the software show the voltage and time scales ? i mean for example 10,20,40,...... like seen on picosope software.
2- i haven't used any oscilloscope yet, do you advice me to offer hantek 6074 , what about picosope 2000 series ?

i appreciate your help

a Pico 2204A ؟ is it good? i think it is old version and i heard that it is not for automotive diagnosis but i don't why it is not .

You can down load the software from Hantek and run it in demo mode the same goes for Pico, Owon and Auto Ditex. Personally I would touch any Hantek scope although the Hantek 1008 is so cheap it is a useful toe in the water learning tool.

questions :

1- has hantek 6074b zoom in features like pico?
2- i cant see voltage and time scales on hantek scope
3- can it save the waves to analyse later ?

thank u

(1) You can stop the scope then change the time base to do a very limited zoom in or out.
(2) As far as I can see the 6074 only comes with the old version of the Hantek software the one with onscreen knob controls which is awful to use. The time per/div is shown next to the knob control for the time base (ie horizontal setting) if set to say 1ms/div for capturing ignition secondary then one big box = 1ms.
The voltage setting for each channel is done in a similar way.
For accurate measurement of time and voltage use the cursors (which are awful to use) or select an onscreen measurement.
(3) Not in any meaningful way.

To be honest what you are really paying for with 6074BE is all the probes they bundle with it some of which are handy some of which you don't need.
