filterCount
The number of readings required for each filtered measurement (1 to 100)
Details
The filter count is the number of readings that are acquired and stored in the filter stack for the
averaging calculation. When the filter count is larger, more filtering is done and the data is less noisy.
This command is set for the selected function.
Example
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.filter.count = 10
smu.measure.filter.type = smu.FILTER_MOVING_AVG
smu.measure.filter.enable = smu.ON
Set the measurement function to
current.
Set the averaging filter type to moving
average, with a filter count of 10.
Enable the averaging filter.
