Dhamodharann
Hi.. Just now i had start to Analyze the quality of the signals in the pcb board. In case manually i want to analyse the signal manually means how can i define the units mm? For the signal explorer the defaults unit of mils get used. Still how to change the units in mm?

    Set the following Environment Variable in the "user section" at the top of the pcbenv\env file

    set SIGXP_ALTERNATE_UNITS "<units> <accuracy>"

    <units> must be one of:
    mils
    inches
    centimeters
    millimeters
    microns
    meters

    <accuracy> can be 0 to 5

    for example:
    set SIGXP_ALTERNATE_UNITS "millimeters 2"
    will use units of mm and accuracy of 2 decimal places.
