smuX.nvbufferY.capacity
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Capacity of the buffer.
Usage
capacity = smuX.nvbufferY.capacity
Remarks
• Reading this attribute returns the number of readings that can be stored in the
buffer.
• A buffer with only basic collection items turned on can store over 100,000 readings.
Capacity does not change as readings fill the buffer. Turning on additional collection
items, such as timestamps and source values, decreases the capacity of the buffer.
• This is a read-only attribute.
Details

Example
Read the capacity of SMU A buffer 1:
capacity = smua.nvbuffer1.capacity
print(capacity)
Output:
1.05
smuX.nvbufferY.clear
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Function
Clears the buffer.
Usage

Remarks
This function clears all readings from the indicated buffer.

smuX.nvbufferY.collectsourcevalues
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Source value collection for the buffer.
Usage
state = smuX.nvbufferY.collectsourcevalues
-- Reads collection state.
smuX.nvbufferY.collectsourcevalues = state
-- Writes collection state.
Set
state
to one of the following values:
0
Source value collection disabled (off).
1
Source value collection enabled (on).
