Set 2700 to perform “x”
number of measurements
(x = 2 to 110000)
2. INIT triggers the measurements, and FETCh? returns the readings. Again sending
FETCh? without first sending INIT will return old readings.
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).

Trigger Configuration
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).
