Hello luminary6, I updated the DDS120 handling again, please check the latest build: https://ci.appveyor.com/project/Ho-Ro/openhantek6022/build/artifacts If you want to test older Win builds, there's also a history: https://ci.appveyor.com/project/Ho-Ro/openhantek6022/history Martin |

1) I download b205 version. 2) I rename my calibration config file (disable). 3) Connect DDS-120 to USB (probes are disconnected). 4) Run old version (b188, x64) and get zero at: CH1 = -0.62 Volt CH2 = -0.41 Volt 5) Reconnect DDS-120 to USB. 6) Run new version (b205, x64) and get zero at: CH1 = 5.96 Volt CH2 = 6.01 Volt Changes in software is wrong. Also i think you can not set calibration data for all users (if different models of DDS-120 have different electronic parts etc ...) May be good way is revert calibration data to 1.0 But official software is working normally and measure is precise, how it working i do-not know. May be official software read calibration data from device? |

I read your message at github and understand that you correct only "gain", but "offset" value you remove from source. --- Quote ---"Ok, no problem, I've just removed your 1.18 : 1.21 correction if there is no conf file and therefore adjusted the specification values accordingly, so it should give a +- 5% accuracy for 1st time users - only offset has to be adopted individually." --- End quote --- I was remove gain section in my config file, and run new version (b205) with only offset in my config file. --- Quote ---EDIT2: Closed issue, luminary6 please check if the scope behaves better when used without conf file. --- End quote --- Voltage gain is fine, measured values close to real. But becouse voltageLimits is divided by calibration value (how i understand after see source code), my old calibration data is not valid for new version of program, and need recalculation. |

I wanted to inform you for those who still have a DDS140 that I am running it in the lotto OS802 software and that it works perfectly on w10 without the need for a driver. I leave capture and link for those who may be interested greetings. https://drive.google.com/drive/folders/1ST3awUa5HEMRMAV_RmmmOf8mwPNBn1TI |
