Buffervar.clear() - Keithley 2651A Reference Manual

Model 2651A High Power System SourceMeter® Instrument Reference Manual
Usage
maxNumber = bufferVar.capacity
maxNumber
bufferVar
Details
This read-only attribute reads the number of readings that can be stored in the buffer.
The buffer's capacity does not change as readings fill the buffer. A dedicated reading buffer that only collects
basic items can store over 140,000 readings. Turning on additional collection items, such as timestamps and
source values, decreases the capacity of a dedicated reading buffer (for example, smua.nvbuffer1), but does
not change the capacity of a user-defined dynamically allocated buffer. A user-defined dynamically allocated
buffer has a fixed capacity that is set when the buffer is created.
See the smuX.nvbufferY attribute for details on accessing dedicated reading buffers. See the
smuX.makebuffer() function for information on creating user-defined dynamically allocated reading buffers.
Example
maxNumber = smua.nvbuffer1.capacity
print(capacity)
