Details
This attribute sets the time interval between measurements when smuX.measure.count is set to a value
greater than 1. The SMU attempts to start each measurement when scheduled. If the SMU cannot keep up with
the interval setting, measurements are made as quickly as possible.
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.
Example
smua.measure.interval = 0.5
Sets the measure interval for SMU channel A to 0.5.

Usage
lowRange = smuX.measure.lowrangeY
smuX.measure.lowrangeY = lowRange
lowRange
The lowest voltage or current measurement range used during autoranging
X
Source-measure unit (SMU) channel (for example, smua.measure.lowrangev
applies to SMU channel A)
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 for SMU channel A to 1 V.
