.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 k
Ω
.
Example
smua.contact.threshold = 5
Set the contact check threshold for SMU channel A to 5
Ω
.

Where saved
Default value
Function
Yes
Usage
bufferVar
= smu
X
.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
smu
X
.nvbuffer
Y
buffers.
