The QUEStionable Status group is used to report warning conditions amongst the voltage, current, pulse timing, frequency and pattern parameters. Warnings occur when a parameter, although not outside its maximum limits, could be causing an invalid signal at the output because of the actual settings and uncertainties of related parameters.
