Returns selected information about the MeasurementData. The returned Value is an object and may be a boolean, short, integer, float, double, string, or an array of numbers. For example, use this["TrcLedStr"] to get the trace indicator string (e.g. "CAL?") and use this[TrcLedReason"] to get the reason behind the indicator (e.g. "Calibration data is unavailable."). The available MeasurementData information is the same information as the saved Trace Data Header information. For more information and a list of the available trace data header variables, see the "Data Header Variables" topic in the "Shared Data with Other Applications" book of the online help.
