Remarks
• There are two averaging filter types to choose from: Repeating and moving. For the
repeating filter (which is the power-on default), the stack (filter count) is filled, and
the conversions are averaged to yield a reading. The stack is then cleared, and the
process starts over.
The moving average filter uses a first-in, first-out stack. When the stack (filter count)
becomes full, the measurement conversions are averaged, yielding a reading. For
each subsequent conversion placed into the stack, the oldest conversion is
discarded. The stack is re-averaged, yielding a new reading.
• The
reset
function selects the repeat filter.

Example
Selects the moving average filter for SMU A:
smua.measure.filter.type = smua.FILTER_MOVING_AVG
smuX.measure.interval
X = SMU channel (a or b)
Attribute
Interval between multiple measurements.
Usage
interval = smuX.measure.interval
-- Reads measure interval.
smuX.measure.interval = interval
-- Writes measure interval.
interval
Set interval (in seconds) from 0 to 1.
Remarks
• This attribute sets the time interval between groups of measurements when
smua.measure.count
is set to a value greater than 1. The SMU will do its best to
start the measurement of each group when scheduled.
• If filtered measurements are being made, this interval is from the start of the first
measurement for the filtered reading to the first measurement for a subsequent
filtered reading. Extra measurements made to satisfy a filtered reading are not
paced by this interval.
• If the SMU cannot keep up with the interval setting, measurements will be made as
fast as possible.
• The
reset
function sets the measure interval to 0.

Sets measure interval for SMU A:
smua.measure.interval = 0.5
