bufferVar.timestampresolution
This attribute contains the resolution of the timestamp.
Usage
resolution = bufferVar.timestampresolution
Timestamp resolution in seconds (minimum 1 µs)
The reading buffer; can be a dynamically allocated user-defined buffer or a dedicated
reading buffer
Details
Assigning a value to this attribute sets the resolution for the timestamps. Reading this attribute returns
the timestamp resolution value. This value can only be changed with an empty buffer. Empty the
buffer using the bufferVar.clear() function.
The finest timestamp resolution is 0.000001 seconds (1 μs). At this resolution, the reading buffer can
store unique timestamps for up to 71 minutes. This value can be increased for very long tests.
The value specified when setting this attribute will be rounded to an even power of 2 µs.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
Example
smua.nvbuffer1.timestampresolution = 0.000008
Sets the timestamp resolution of
dedicated reading buffer 1 to 8 μs.
