7: TSP command reference Series 2600B System SourceMeter® Instrument

Details
Assigning a value to this attribute enables or disables the storage of source values. Reading this attribute returns
the state of source value collection. This value can only be changed with an empty buffer. Empty the buffer using
the bufferVar.clear() function.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
When on, source values will be stored with readings in the buffer. This requires four extra bytes of storage for
each reading. Turning on additional collection items, such as source values (this attribute) and timestamps,
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.
Example
smua.nvbuffer1.collectsourcevalues = 1
Include source values with readings for
dedicated reading buffer 1 (source-measure

bufferVar.collecttimestamps
This attribute sets whether or not timestamp values are stored with the readings in the buffer.
Type TSP-Link accessible Affected by Where saved Default value
Usage
state = bufferVar.collecttimestamps
bufferVar.collecttimestamps = state
Timestamp value collection status; set to one of the following:
• 0: Timestamp value collection disabled (off)
•
: Timestamp value collection enabled (on)
The reading buffer. Can be a dynamically allocated user-defined buffer or a
dedicated reading buffer.
