IEC Mode Command Summary - E

MEASure:ARRay:VOLTage:FLUCtuations:PST?

This query measures voltage fluctuations in accordance with the IEC 868 standard. It is only available when IEC mode is selected with SYSTem:CONFigure. The parameter specifies the number of Pst integration periods for which data will be returned in response to the query. This query returns 1 data structure per specified integration period for a total of <n> structures.

For example: If CALCulate:INTegral:TIME specifies 10 minutes and <n> is set to 12, a 2 hour measurement is initiated (10 minutes times 12) and 12 structures are returned. Since there are 14 data points per structure, a total of 168 points are returned. The structure includes flicker perceptibility values for the component percentiles making up Pst, the Pst value itself, various RMS voltage values (Dmax, Dc, and Dt), together with indices for these RMS values that give their approximate location in the RMS time series for the corresponding integration period.

This command is closely related to two similar commands that return different types of data (see MEAS:ARR:VOLT:FLUC:FLIC and MEAS:ARR:VOLT:FLUC:ALL). Record numbering begins with one. The figure below defines the structure of the data returned by this query:
