Exercise 6 — Trigger and return multiple readings
Trigger Configuration
Trigger and Return
1. In order to trigger and return multiple readings, the buffer must first be cleared of
readings that were stored by the TRACe command or front panel operation (see
Section 6 for details on buffer operation).
2. INIT triggers the measurements and FETCh? returns the readings. Again, sending
FETCh? without first sending INIT will return old readings.
3. READ? performs an INIT to trigger the measurements and then FETCh? to return
the reading(s).
4. Triggered readings are automatically stored in the buffer. Statistics for buffer readings
are also stored in the buffer. CALC2 commands are used to calculate and return
buffer statistics (see Section 6 for details).
