measurements are a moving average of the latest 2, 4, 8, or 16 measurements.
All MEASure and FETCh queries return the measurement presently stored in the buffer, and both BUS
and IMMediate triggers are ignored.
FETCh:ALL?
MEASure:ALL?
Returns all measurements, except FREQuency, as a comma-separated list. Every returned item is
available, regardless of the measurement coupling or output coupling.
Parameter
Typical Return
(none)
+1.00
Return the average measured AC output current:
FETCh:CURRent:AC?
The values are returned in the order shown below, using the format 1.00.
The formulas are similar for voltage and current. All raw measurements (individual A/D conversions
and associated array elements), are understood to be DC coupled. This discussion does not consider
the effects of windowing (used to ensure stable readings) and adjustments that must be made to
correct for window gain (always less than unity when compared to a rectangular window).
General definitions are as follows:
Array Length: N
Array Index Variable: n = 0, 1, 2, ..., N-1
Voltage Array: Volt[N]
Current Array: Current[N]
FETCh/MEASure Query
Notes
CURRent[:DC]?
Average DC current (A)
This command applies to DC, AC+DC, and EXT-DC.
Set the averaging period using
.
CURRent:AC?
AC current (Arms)
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
