Explanation of Functions
Realtime Recording to the Internal Hard Disk (Option) «For procedures, see section
7.5.»
The data can be recorded in realtime to the internal hard disk (option). The stored data
can be recalled. The realtime recording area is allocated on the internal hard disk in
advance (the default value is 50% of the entire capacity of the internal hard disk). You
can set the realtime recording area in the range of 30% to 70% of the entire capacity of
the internal hard disk when you format the internal hard disk (see section 13.6).
The time axis range and the maximum sample rate that allow realtime recording vary
depending on the number of channels to be recorded in realtime. For details, see
appendix 3.
The following two modes of realtime recording operation are available.
Single:
Starts realtime recording with the start of waveform acquisition and stops
realtime recording when the specified record time is reached.
Continue: Starts realtime recording with the start of waveform acquisition and stops
realtime recording when the specified record time is reached. This
sequence is repeated the specified number of times (count).
If you select Single, Auto or Log trigger modes are available. If you select Continue, only
Log is valid.
Auto:
Acquisition is started by pressing START. If the specified record time is
exceeded, old data is overwritten. Acquisition continues until you press
STOP.
Log:
Acquisition is started by pressing START. When the specified record time is
reached, acquisition stops.
