The FETCh? query is a function that allows you to query results from a measurement that was previously INITiated. It does NOT begin a measurement. If no measurement is in progress it returns the integrity and measurement values from the last measurement made, or return an integrity of No Result Available and results of NAN. If a measurement is in process, the query hangs until the results are available, or the measurement fails or times out. The exact results returned by a FETCh? depends on the specific measurement. A measurement may have a number of different results or combination of results for a FETCh?. The FETCh? queries are intended to be used to provide overlapped operation access to measurement results from the test set. When used along with SETup and INITiate commands , FETCh? is the primary way for you to retrieve measurement results. In order to use the test set's concurrent test capabilities the overlapped commands of INITiate and FETCh? must be used. Overlapped commands allow you to send commands and not wait for completion.
For details of the FETCh? commands refer to the FETCh? subsystems in this section.
For details on commands that are used to perform data processing on measurement results, refer to the CALCulate Subsystem.
