Hantek DSO2D15 Digital Storage Lab Oscilloscopes150MHz Bandwidth 2CH Dual Channel 1GSa/s 8M Memory Depth with 1CH Waveform Generator with High Voltage Probe

Me aparece la leyenda “Sígnal Source not supported” Ya actualice el l firmware y sigue sin funcionar. Espero me resuelvan los de Hantek.

I bought this scope for the sole purpose of using it as benchtop voltmeter and to see some waveforms on that voltage. Just so the reader is aware, I do have more than one scope, and my good one is an $8,000 oscilloscope by Rigol.The problems;* The rotary encoder (or firmware) on the V/div knob on ch1 skips and has dead spots* Noisy front end, even when front end shunted to ground or internally grounded.* Ch1 has a +120mv dc offset - very bad!* Ch2 has a +93mv dv offset - very bad!* Calibration connection pulse out is loose, but ground calibration connection is solidI know a lot of YouTubers recommend it, but look at the source, people who dont use a scope or this is their 1st scope or they already have a cheapo hand held $50 scope and want a bench scope.If you are looking for an oscilloscope to actually use as a scope, save your money, buy a decent brand such as Keysight, Rigol, Tek, etc..Update: I had to return the unit same day. When measuring 1.5v DC it showed 1.73 volts, when measuring a precision 1Khz 2vp-p square wave, it showed a dv offset of .13v and a PW of 480us, thats huge, 20us is huge in the domain I work.

I am going to keep this brief but concise. The response time of this scope is something to be noted right up front. It's slow... as you make adjustments to the scope to capture the desired signal, be prepared for lots of latency. I could potentially put up with this, but, I purchased this scope for the serial decoder function and it's just broken. besides any usable documentation, which I can work around and usually do, the implementation is broken. When attempting to capture and review IIC data, the scope would frequently lockup. It was unusable. It's possible that this device is defective, but then that wouldn't say much for Hantek's QC. It's not worth the headache. You get what you pay for and don't expect much for this scope and it's decoding functionality. Even as a basic scope for signal analysis , I would look elsewhere. Very disappointed in this purchase. BTW I own several Digital and analog Oscopes and have been using test equipment for 38 years. I am an experienced Senior Field Service Engineer. I am not a novice and I am also and advanced user with Arduino and RPI SOC processors. Good luck!

Cannot say enough good about it. Its not a Tektronix but for small business and home tech, you cannot beat it. We should be making this here. This could be 95% completely built here by automation and sold for a similar price. But "free trade" has ruined manufacturing in this country and shipped it to countries who may or may not be our friendsLove the Chinese, just not the Party.

I admit, I've always wanted one since my college days when we used HP's with a poloroid camera to capture a trace. I'm a retired engineer and relearning/redoing my electrical labs is what I'm playing with. So far I've done just the basics....bouht a sub $20 signal generator, and the oscilloscope is good enough to show how bad the signal generator is (square waves aren't quite so square). The PC part is sort like worth $50 just for all the advance stuff it does...I imagine its great for college students to learn the basics of electronic components such as RC circuits, diff types of transistors (opamps, diff, etc)
