Hi guys,
I'm brand new to oscilloscopes, and still fairly new to electronics. I've only used oscilloscopes a couple of times in my entire life, and it was an old Rigol unit at Hackerspace. Yesterday I found a brand new (plugged in once or twice) Hantek 6022BL scope one suburb away from me, and I couldn't help biting the bullet and buying it.
After installing the standard software, I plugged the probe into the cal port, and it looked like it was giving a perfect 1MHz square wave, with 5v P-P. Only a... couple of problems with this.
Problem the first: that calibration terminal spits out 1KHz, not 1MHz. And it's 2v peak-to-peak, not 5v. ...and it will produce these square waves, on both channels, with nothing connected. There is nothing on the BNC's at all. I've been tearing my hair out all night, and all morning, trying to get this thing to do something meaningful, and I've reinstalled drivers countless times. Also, probing the points with a multimeter produces no meaninfgul results, either.
I tried to install OpenHantek, which fails with the following error:
libpng warning: iCCP: known incorrect sRGB profile
Which is a very weirdo error to be getting for an oscilloscope program. I tried throwing software at the problem to make it go away, but to no avail. I did manage to wrap my tiny mind around sigrok/PulseView, though, and the driver does work, and it seems to upload the correct firmware when the scope starts. It seems to, but I honestly don't know. I'm brand new to scopes, and I have no idea what's going on here.
I will try on a different computer after I post this, and will see how I go. But I've done all the usual things, fiddled with the buttons, taken the thing apart to see if anything obvious was amiss, nothing is, nothing has a hole in it, nothing appears wrong. The scope starts, and the LED goes from flashing red to flashing green when "in operation", nothing appears to be wrong, but the scope isn't really doing anything that I can suss out either.
I'm honestly lost. I'll be heartbroken if this scope is a dud, because I've literally wanted an oscilloscope for about 10 years now, it's been at the top of the electronics wishlist for many, many years, and now that I finally have one, I can't get any chooch out of it.
Any ideas? I really hope I'm just doing something wrong.
Thanks in advance, and I do look forward to contributing to these forums now that I'm getting into electronics more.
Cheers,
Rory
