I have a Hantek 1008C which I was OK with for my automotive needs until last week.
I have strong vibrations on my car and a strange grinding noise ocassionally.
With my Hantek I was using an analog Accelerometerattached to a magnet with some hot glue.This I had on the rear diff casing.
I can clearly see the vibration. With an optic sensor I see the shaft position according to vibration.
It seems that I don't have any spikes when than horrible grinding noise occurs.
So I need to look elsewhere for the source of the noise.

I was going to replace the U-Joints and then balance the shaft with the help of two hose clamps.
The propblem is that when I reduce the ms of the Hantek then I don't get a steady flow of data anymore which would show me an usable amplitude.
Not sure if this is the Hantek, my USB driver or cable or something else.
Let me doublecheck the ms I had selected and get back to here with the info.

Is the Hantek really that slow for not even being able to balance a shaft?
I had problems before reading 60Hz as well.

Hence my thought to upgrade to a better scope and better software.
Which one would you chose, and why: Pico 2204A or 2205A?

 

At some point you need to do some additional diagnostic checking. For starters, U-joints do not produce a grinding noise, they produce a vibration proportional to vehicle speed. A grinding noise is more likely either a bearing or the brakes or possibly even a gear in the differential. But the first thing to check is for the rear brakes constantly being rubbing.
The easy way to detect brake rubbing is to jack up one wheel so that it can be turned by hand. Brake rub is easy to feel, grinding bearings also. You need to do this with the car on a level surface so it will not tend to roll.

 

Thank you.
But this thread is about what Oscilloscope to buy not on how to troubleshoot cars.

 

Generally, Picoscopes are good, rather modern and trustably made, however not most cheapest on the markets.

I concur that the picoscope line is a quite good product, with truthful specifications given.

 

You didn't mention budget. If budget isn't an issue, I've used a Fluke in an industrial setting and it was quite nice. Not as fancy as a scope that you would have in the lab, but durable and appropriate options for that type of use. This one also came up when I googled the Fluke, I don't know anything about this brand but it's less than 1/10 the price of the Fluke, only 1 channel though:

Thank you.

Certainly true about the posted question. BUT pointing out an incorrect diagnosis to avoid an un-needed expense was a courtesy.

 

Thank you for all on-topic insights, comments and opinions.
I was giving the usage-example to determine whether I need the
2205A which I have ordered in the end, or if I would be happy with the
2204A. the direrrence are 10mhz to 25mhz.
But both are combinded ground and USB2.0 devices.

I will see how that goes and one day if I am better situated then I will go for a 4 channel one with individual ground, UBS3 and some more heartbeats.
