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 See “Reading buffers” in this section and in Section 7.
Also see smuX.measure.overlappedY, smuX.measure.Y, smuX.nvbufferY
Example Read the capacity of SMU A buffer 1:
capacity = smua.nvbuffer1.capacity
print(capacity)
Output: 1.123410+05
smuX.nvbufferY.clear
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Function Clears the buffer.
Usage
smuX.nvbufferY.clear()
Remarks This function clears all readings from the indicated buffer.
Details See “Reading buffers” in this section and in Section 7.
Also see smuX.measure.overlappedY, smuX.measure.Y, smuX.nvbufferY
Example Clears SMU A buffer 1:
smua.nvbuffer1.clear()
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).
