Re: Sending screen error

Sorry, I hadn't enlarge the photo and thought that was a frequency meter. Does the voltage reading change if the meter is connected to the signal long time? I ask this question because, from the video, the signal was normal at beginning. Otherwise, If scope is good and signal is good then the probl...

Re: Sending screen error

Do you know the amplitude of 1KHz signal for bus pirate? If it matches the scope reading then scope is good. The amplitude of test signal could be wrong. The amplitude of 1KHz signal for bus pirate is 3.3V and it matches! You have checked the frequency of test signal. But correct frequency doesn't ...

Re: Sending screen error

Thank you! I saw the video finally. For the issue I'd suggest you first check the scope with some DC source of known voltage (like a battery or regulated power supply). This is to verify that the gain/attenuation of analog channel is correct. If the gain is correct then reproduce the issue. Touch c...

Re: Sending screen error

I am sorry we are unable to open Youtube from within China. Please email the file to jyetek@gmail.com. Thank you. Try this service ! I think that it could work. Put you the url of youtube video into text label and it should encrypt the streaming autonomously and anonymously. The video is in high re...

Re: Sending screen error

I think the voltages you measured were OK. -7.16 isn't much different from -7.0. And this voltage is the negative power supply of analog circuits. It is not related to test signal output. For test signal problem can you please post a photo for what you saw? Excuse me for delay, I haven't received t...

Re: Sending screen error

The messages PC received only indicated the transmission from scope to PC was good but not necessarily the other way was also okay. Now since screen sending didn't work it is better to verify no hardware problem first. One way to do this is to make PC constantly send out some bytes and use a scope ...

Re: Sending screen error

Which software did you use for receiving? I used both Putty and your Terminal application ( configuration 38400 baud 8n1 ). Did you verify that the transfer from PC to 062 is working? It work, because If you give attention :geek: at first lines of screen capture, you can see: COM 0 OK WWW.JYETECH.C...

Sending screen error

I have an older version of DSO 062A that I updated to firmware version 113-06201-201 yesterday. If I try to send a screen capture on pc through a CP2102 UART-USB adapter I receive a "Send failed" and this message (the first lines come from init): COM 0 OK WWW.JYETECH.COM FW: 113-06201-201þ...
