2.4 Setting Waveform Acquisition Conditions and Display Conditions
Realtime Recording to the Internal Hard Disk (Option) <Section 7.7>
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 13.5).
The time axis settings, the maximum record length, and the maximum sampling rate that
allow realtime recording vary depending on the number of channels to be recorded in
realtime as follows.
Channels Used Time Axis Range Maximum Maximum
Record Length Sample Rate
18 CH or more 20 s/div to 3 day/div 25 MW 5 kS/s
12 to 17CH 20 s/div to 3 day/div 50 MW 5 kS/s
6 to 11CH 6 s/div to 3 day/div 50 MW 10 kS/s
4 to 5CH 3 s/div to 3 day/div 100 MW 20 kS/s
3CH 2 s/div to 3 day/div 250 MW 50 kS/s
2CH 1 s/div to 3 day/div 500 MW 100 kS/s
1CH 1 s/div to 3 day/div 1 GW 100 kS/s
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 length is reached.
Continue: Starts realtime recording with the start of waveform acquisition and stops
realtime recording when the specified record length is reached. This
sequence is repeated the specified number of times (count).
If you select Single, the following two trigger modes are available. If you select
Continue, only Log is valid.
Auto: Acquisition is started by pressing START. If the specified record length is
exceeded, old data is overwritten. Acquisition continues until you press STOP.
Log: Acquisition is started by pressing START. When the specified record length is
reached, acquisition stops.
