MEASure:ARRay:VOLTage:FLUCtuations:FLICker?
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 during which voltage fluctuation arrays will be returned in response to the query. The
data contained within the arrays represents RMS voltage values integrated over successive half line
cycles and the corresponding instantaneous flicker values. This query returns structured data at a rate of
one packet per second, with each packet contained 202 (50Hz) or 242 (60Hz) data points, for a period of
time determined by the specified CALCulate:INTegral:TIME and the parameter specifying the number of
Pst integration periods.
For example (assuming 50Hz operation): If CALCulate:INTegral:TIME specifies 10 minutes and <n> is
set to 12, a 2 hour measurement is initiated (10 minutes times 12) and 1,454,400 (202 points/sec times 60
times 10 minutes times 12) data points are returned.
This command is closely related to two similar commands that return different types of data (see
MEAS:ARR:VOLT:FLUC:PST and MEAS:ARR:VOLT:FLUC:ALL). Record numbering begins with
one. The figure below defines the structure of the data returned by this query:
