50 Sequoia Series
4.4 Array Measurement Subsystem
This command subsystem lets you retrieve arrays containing measurement data. Only current and
voltage measurements are stored in an array. Two measurement commands are available: MEASure
and FETCh. A MEASure command triggers the acquisition of new data before returning the readings
from the array. A FETCh command returns previously acquired data from the array.
Individual outputs of a three-phase source are specified by the setting of INSTrument:NSELect.
