Good morning everyone. I'm Brazilian and I need help from geniuses. Because when it had the option of peak to peak the values gave different. In a 3db sinusoid I get the RMS value and multiply it by 1. Well these values did not hit before and now with this update. I calibrated the tip x10 and x and nothing.Arma 3 ace dog tags
Please someone help me? Thank you. Hello crsojr welcome to the forum.Active ecommerce cms v1 9
I saw your other post on Hantek's forum as well. The values showed by the device are correct. If I understood correctly, you are just mixing the concepts of peak-to-peak and maximum and minimum values.
I can understand the confusion because in the earlier versions of the firmware this scope used to show the peak-to-peak measure, in the latest FW Hantek changed it to show the MAX and MIN, that is the maximum or minimum amplitude of the signal from zero ground.
The following users thanked this post: crsojr. Hello Microchip grateful for your response. I understood what you wrote. I expressed myself wrong. What happens is that before the old firmware when it appeared the option pico-pico the value was not correct. In the sinusoid at 60 Hz in 3 db the peak value is the RMS value x 1. When I put the oscilloscope to measure the peak-to-peak value that should be 2 x peak went wrong. I left 2 videos in google drive one with the tip x10 and another with the tip x Please see it.
I can not find any parameters for this result on the oscilloscope. Can you help me? Thank you very much. Eu me expressei errado. Por favor veja. Pode me ajudar? Muito obrigado. Hello, how are you?Jjrc drone instructions
Please could you help me, I saw in your post that you also have a Hantek 2C For mine when I have a true rms multimeter and with 2C42 the MAX and MIN value that would be of peak peak is different from that marked by the multimeter and calculated according to grammar.Welcome, Guest.

I was a little surprised to see no discussion started yet on some new Hantek gear that has appeared recently. So I thought I'd sign up and start one! Barring any bugs or hardware issues, I think this'll turn out to be a convenient device for quickly getting out during prototyping and doing some probing.
With any luck there will be some kind of bode plot function perhaps using the USB cable and the software for validating audio frequency filters.
Hopefully that gets the discussion started. The following users thanked this post: KWKolb. As a professional EE, I think I'll find it useful as a supplement to a bench scope as long as I'm aware of it's limitations. Microcheap Regular Contributor Posts: Country:. Would you mind tell us where did you buy it and how much?

It has all the basics, but very little beyond that. There is a wave-ish squiggle, but it doesn't change when I change coupling or bandwidth limit. Can trigger on either channel, and you can set the trigger voltage.

It is already of the correct value. Quote from: gf on April 07,pm. The numbers look pretty reasonable. Consequently, in order to source the same output current, a larger R set value is required for the DAC Likely the calibration can still fix the difference, but keep in mind that a full-scale output current of Instead of a coax cable, the probe in 1x setting might work as well if you manage to avoid a loose contact for the duration of the calibration.
Btw, don't forget to auto-calibrate the scope first before you calibrate the AWG. But well, they didn't - maybe because it would require a BNC to banana cable gf.
As already written in my previous post, screen upside-down with white background. Calibration success!!! Going to scope screen, the sinusoid is perfectly tuned mV mV, perfectly centered offset 0. At this point I update the firmware with the last dfu available, but when I swith the scope on, I have a big surprise It seems that the firmware update reset calibration, or the old calibration firmware does not save the calibration data at all.
Any trick to maintain calibration with up-to-date firmware? IMO they are saved. Just a guess : Maybe the AWG calibration data are reset by the firmware deliberately if the device model is not a 2Dx2, in order to motivate people to buy a 2Dx2? If the firmware or the firmware upgrade would reset the calibration data unconditionally, then the device could never retain the factory calibration. So Hantek had the need to provide a solution in order that users of the buggy firmware can re-create the lost calibration data.
Later, the feature disappeared again. Quote from: gf on April 11,am. Tried newly the AWG calibration. Switch off and then on the scope The firmware is the same for all models, so it's strange that it behaves differently.
The only thing that comes to mind is that there are some operations to do after calibration, to make the data permanent. Microcheap Regular Contributor Posts: Country:. I decide to test it now and indeed, the screen is inverted. Regarding it not holding the calibration data, try to restore the device to factory default to see if it makes any difference.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
