Details
This attribute sets the time interval between measurements when
smu
X
.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.

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.
