    Hello sir, 
    

    I'm experiencing unexpected behavior with my ADALM1000 kit

    Background: During a test, I generated 1Hz square wave for the counter IC using python programing and generated 1Hz clock signal however, after this , the kit seems to be generating a square wave on both the Channel-A and B. Even when I select different signals in Pixel pulse/Alice, the output doesn't change. It seems the reference signal has been permanently configured as a square wave. 
    

    I also have calibration issue, voltage in Pixlepulse/Alice  is showing 1000v 
    

    

    Kindly guide how to fix this issue.

      Assuming the device does not come back to proper operation after power cycling it, and given the 1000V readings I would guess that the calibration / firmware has been corrupted. Assuming you have libsmu installed (a must to have ALICE work) go the command line and type:
      

      >smu
      


      smu: utility for managing M1K devices
      

      -h, --help print this help message and exit
       --version show libsmu version
       -l, --list-devices list supported devices currently attached to the system
       -p, --hotplug-devices simple session device hotplug testing
       -s, --stream-samples stream samples to stdout from a single attached device
       -d, --display-calibration display calibration data from all attached devices
       -r, --reset-calibration reset calibration data to the defaults on all attached devices
       -w, --write-calibration <cal file> write calibration data to a single attached device
       -f, --flash <firmware image> flash firmware image to a single attached device
      

      The smu command line utility will show the above list of options.
      

      the -r option will reset the calibration data to the factory defaults on all attached devices. Give that a try. If that does nor help then it may require the firmware to be re-flashed. firmware image file available  here:
      

      github.com/.../m1000-2.17.bin
      

      If that does not return the board to proper operation then there is not much that can be done short of replacing the board.
