Buffervar.fillcount - Keithley 2651A Reference Manual

Section 7: Command reference
Usage
state = bufferVar.collecttimestamps
bufferVar.collecttimestamps = state
state
bufferVar
Details
Assigning a value to this attribute enables or disables the storage of timestamps. Reading this attribute returns
the state of timestamp collection. This value can only be changed with an empty buffer. Empty the buffer using
the bufferVar.clear() function.
When on, timestamp values will be stored with readings in the buffer. This requires four extra bytes of storage
per reading. Turning on additional collection items, such as timestamps (this attribute) 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.
This value, off or on, can only be changed when the buffer is empty. Empty the buffer using the
bufferVar.clear() function.
Example
smua.nvbuffer1.collecttimestamps = 1
