smuX.contact.threshold
This attribute stores the resistance threshold for the smuX.contact.check() function. This attribute is not
available on the Models 2604B/2614B/2634B.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW)
Yes
Instrument reset
SMU reset
Recall setup
Not saved
50 (50 Ω)
Usage
rValue = smuX.contact.threshold
smuX.contact.threshold = rValue
rValue
The resistance above which contact check should fail (measured in ohms)
X
Source-measure unit (SMU) channel (for example, smua.contact.threshold
applies to SMU channel A)
Details
The threshold should be set to less than 1 kΩ.
Example
smua.contact.threshold = 5
Set the contact check threshold for SMU channel A to 5
Ω
.

smuX.makebuffer()
This function creates a reading buffer.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
bufferVar = smuX.makebuffer(bufferSize)
bufferVar
The created reading buffer
X
Source-measure unit (SMU) channel (for example, smua.makebuffer() applies
to SMU channel A)
bufferSize
Maximum number of readings that can be stored
Details
Reading buffers can be created and allocated dynamically using this function. Use bufferSize to
designate the number of readings the buffer can store.
Dynamically allocated reading buffers can be used interchangeably with the smuX.nvbufferY
buffers.
