Details
This attribute sets the time interval between measurements when smua.measure.count is set to a
value greater than 1.
The SMU attempts to start each measurement when scheduled. When the pulser is disabled, if the
SMU cannot keep up with the interval setting, measurements are made as quickly as possible. When
the pulser is enabled and the trigger model is not configured for asynchronous measurements, if the
SMU cannot keep up with the interval setting, it aborts the sweep and turns the output off.
If filtered measurements are being made, the time 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.
When the measure count is greater than 1 and the pulser is enabled, the measure interval must be
less than 65 ms.
Example
smua.measure.interval = 0.5
Sets the measure interval to 0.5 s.

Usage
lowRange = smua.measure.lowrangeY
smua.measure.lowrangeY = lowRange
lowRange
The lowest voltage or current measurement range used during autoranging
Y
SMU measure function (v = voltage, i = current)
Details
This attribute is used with autoranging to put a lower bound on the range used. Since lower ranges
generally require greater settling times, setting a lowest range limit might make measurements
require less settling time.
If the instrument is set to autorange and it is on a range lower than the one specified, the range is
changed to the lowRange range value.
Example
smua.measure.lowrangev = 1
Sets voltage low range to 1 V.
