Store mode
Store mode setup:
Single transient recording ends after first trigger
Continuous (Max. 1500 rec.) consecutive transient
recording until user stops the measurement or instrument
runs out of storage memory. Every consecutive transient
recording will be treated as a separate record.
By default, 200 records can be recorded. This value can be
changed, if necessary. More than 200 records can slow
down the instrument.
