smuX.contact.threshold
This attribute stores the resistance threshold for the smuX.contact.check() function. This command is not
available on the 2604B, 2614B, or 2634B.

50 (50 Ω)
Usage
rValue = smuX.contact.threshold
smuX.contact.threshold = rValue
rValue
The resistance above which contact check fails (measured in ohms)
X
Source-measure unit (SMU) channel (for example, smua.contact.threshold
applies to SMU channel A)
Details
Set the threshold 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.

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
You can use this function to create and dynamically allocate reading buffers. Use bufferSize to
designate the number of readings the buffer can store.
You can use dynamically allocated reading buffers interchangeably with the
smuX.nvbufferY buffers.
