smuX.measure.interval
This attribute sets the interval between multiple measurements.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Instrument reset
SMU reset
Recall setup
Saved setup 0 (0 s)
Usage
interval = smuX.measure.interval
smuX.measure.interval = interval
interval
The interval value (in seconds); set to a value between 0 and 1
X
Source-measure unit (SMU) channel (for example,
smua.measure.interval applies to SMU channel A)
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.

smuX.measure.lowrangeY
This attribute sets the lowest measurement range that is used when the instrument is autoranging.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Instrument reset
SMU reset
Recall setup
Saved setup Current: 1e-9 (1 nA)
Voltage: 200 (200 V)
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)
