Let me introduce the Hantek 2C42 handheld 40Mhz bandwidth 2-in-1 oscilloscope and multimeter – my latest acquisition, ideal for lugging around and complete with decent carry-case.
As some of you know, I spend my year travelling between Spain and the UK, sometimes by plane, sometimes by car. Dragging a fully fledged oscilloscope back and forth using the first mode of transport above isn’t ideal – hence a small scope is ideal. Combining that with a decent meter is even better. For the boat ride I share the car with my wife and 3 cats, so space is still at a premium.
There are four variations in this range: 2C42/2C72/2D42/2D72
'C' means 2 channel scope and DMM.
'D' means 2 channel scope, DMM and AWG.
'4' means 40MHz.
'7' means 70Mhz.
I got the basic model Oscilloscope + DMM, 40Mhz model – you may be interested in this or another model. Hantek claim that the display can be seen even in bright sunlight. Here in the Northeast of England it might be a while before I can test that feature.
My unit has an AWG button common to all models in the range but the model I have has no waveform generator.
This scope is not going to compete with my desktop Owon scope but is certainly handy for travel. Clearly this leaves the little “Nano” scopes wanting, convenient though the Aarontek model I recently looked at is. There is of course a size and price difference.
Display resolution is 320x240, display size is 3 x 4.9 inches, maximum real-time sampling is 250M samples/sec.
Apparently, Hantek is a non-profit group – I didn’t know that and I will be looking at other products in their range in the future.
More info: Record length is max 6K for a single channel, 3K for dual-channel. Resolution is 8-bits.
Rather than go into great detail here about the specs including the multimeter specs, I refer you back to the Banggood site lower down. Bear in mind when looking at the Banggood link that this model is 2-in-1, not 3-in-1
As you may note in the photo you get a complete set of meter leads but only 1 scope lead. Thankfully I have others. You also get a type C USB charging lead and miniature USB supply which apparently charges at up to 2 amps. The unit normally runs on it’s internal rechargeable 18650 Lithium batteries. The claim is that you will get a full day’s working and over 8 weeks standby on a full charge.
Manual, software for PC, firmware and more available from the Hantek site. At this early stage I’ve loaded the software on my Windows 10 PC but the driver is not seeing the scope. So the unit runs fine stand alone but I’ve yet to verify PC operation. Right now as the USB and SD connectors are not fitted on my unit, it is looking like this model does not support PC operation. I’ll seek clarification.
