Explanation
The data can be recorded in realtime to the internal hard disk (optional).
The internal hard disk consists of the following drives.
Realtime:
For realtime recording. 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).
HD-0, HD-1*: For saving various data.
*
HD-0 only if the internal hard disk is partitioned to 2; HD-0 and HD-1 if the internal hard disk is
partitioned to 3.
Waveforms That Are Realtime Recorded
All normal waveforms displayed on the screen are realtime recorded.
Possible Time Axis Range, Maximum Record Length, and Maximum Sample Rate
for Realtime Recording
Varies depending on the number of channels that are to be realtime recorded as follows:
Number or Channels
Time Axis Range
Maximum
Maximum
Record Length
Samlpe Rate
18 channels or more
20 s/div to 3 day/div
25 MW
5 kS/s
12 to 17 channels
20 s/div to 3 day/div
50 MW
5 kS/s
6 to 11 channels
6 s/div to 3 day/div
50 MW
10 kS/s
4 to 5 channels
3 s/div to 3 day/div
100 MW
20 kS/s
3 channels
2 s/div to 3 day/div
250 MW
50 kS/s
2 channels
1 s/div to 3 day/div
500 MW
100 kS/s
1 channel
1 s/div to 3 day/div
1 GW
100 kS/s
Realtime recording is possible within the maximum record length and maxim sample rate
ranges of the number of channels to be realtime recorded.
The setting shown above is common to all models (memory options standard, M1, M2,
and M3).
Realtime Recording Mode
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.
Sequence/Count
Single:
Acquisition is started by pressing START. When the specified record length is
reached, acquisition stops.
Continue: Acquisition is started by pressing START. When the specified record length is
reached, acquisition stops. This sequence is repeated the specified number
of times (count).
Auto Naming
File names are automatically created during realtime recording. You can also enter
comments. The following three auto naming types are available.
• OFF
File name specified by File Name (up to 16 characters).
• Numbering
Automatically creates files by attaching a four-digit number, 0000 to 4999, to the file
name. You can assign a common name before the number (Specified with File
Name. Up to 4 characters).
