Hantek 2000 series - 2C42/2C72/2D42/2D72

salvagedcircuitry:
Just found this video on youtube on the 2D42 posted literally yesterday :scared:. The guy goes through a bunch of the functions on the handheld. The waveforms it generates look pretty noisy though, but I still can't get over how reasonable this thing is. $150ish for a not-much-larger-than-calculator portable oscilloscope instrument. Pretty cool. And it runs on bare 18650s! I would love to see this thing tested out with a voltage reference and side by side with a normal scope and function gen. I have no affiliation with youtube channel.

ataradov:
There is no need for a voltage reference, this this has accuracy of a toy. The traces visibly jump when you switch from battery power to the USB power.

Multimeter part may be better though, since it uses a dedicated multimeter chipset.

It is a cool all-in-one thing, but don't expect miracles. It runs on ADCs that are 6 times overcloked from their normal rated clock.

Nikodrengen:
It looks like a fun device for use on the road.
For my use, I need a sinewave with 50 mV RMS amplitude.
Does anyone know the amplitude range supported by the AWG?
Thanks,

I will check when I get home, but I don't remember it being particularly adjustable. I think it changes in 0.1 V increments.

ataradov:
So it looks like it can do 0.01 - 2.5 V with 0.01 V increments. Amplitude you can set by up and down arrows has increments of 0.1 V, but you can call up a keyboard and input any number you like.
