Buffervar.timestamps - Keithley 3700A Series Reference Manual

Section 11: TSP command reference

bufferVar.timestamps

When enabled by the bufferVar.collecttimestamps attribute, this attribute contains the timestamp when
each reading saved in the specified reading buffer occurred.
Type TSP-Link accessible
Attribute (R) Yes
Usage
timestamp = bufferVar.timestamps[N]
timestamp
bufferVar
N
Details
The bufferVar.timestamps information from a reading buffer is only available if the
bufferVar.collecttimestamps attribute is set to 1 (default setting). If it is set to 0, you cannot
access any time information from a reading buffer.
If enabled, this buffer recall attribute is like an array (a Lua table) that contains timestamps, in
seconds, of when each reading occurred. These are relative to the bufferVar.basetimestamp for
the buffer.
Example
printbuffer(1, 6, buffer1.timestamps)
