Buffervar.cachemode - Keithley 2601B Reference Manual

Section 7: TSP command reference
Usage
basetime = bufferVar.basetimestamp
basetime
bufferVar
Details
This read-only attribute contains the timestamp (in seconds) of the first reading stored in a buffer (rb[1] stored
in reading buffer rb). The timestamp is the number of seconds since 12:00 AM January 1, 1970 (UTC) that the
measurement was performed and stored.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
See the smuX.nvbufferY attribute for details on accessing dedicated reading buffers.
Example
basetime = smua.nvbuffer1.basetimestamp
print(basetime)
