Restore the realtime recorded data
The previous realtime recorded data can be recalled to the real time record area by pressing the
“
Restore HD
” soft key.
Note
Please note that the operation is different on the DL708/DL708E.
Saving and loading the realtime recorded waveform data
See section 11.6 “Saving/Loading Waveform Data.”
Points to note when realtime recording
• When the acquisition mode is set to average or sequential store, realtime record cannot be
executed.
• During the realtime record, starting and stopping the recording are the only valid actions.
• Because the maximum record length that can be displayed on the screen is 1 MW, if more
than 2 MW of data is realtime recorded, move the waveform display position with the “Main
Position” soft key of the ZOOM menu to observe the measured data.
• Cursor measurements and automatic measurement of waveform parameters are suspended.
• During realtime printing, history memory waveform/X-Y display waveform/recalled
waveform/zoom waveform/computed waveform cannot be displayed.
• The following operations can be carried out on the data which is realtime recorded to the
hard disk (history memory function is not available).
Cursor measurements and automatic measurement of waveform parameters, zoomed
waveform and computation waveform, X-Y display waveform, loaded waveform, print out,
replay.
• When realtime recording to the internal hard disk, do not connect the PC to the SCSI
connector.
• Up to the first three points of data become undefined on the waveform immediately after the
start of the realtime recording.
The number of points that become undefined depends on the sample rate.
Note
When the realtime recording is started, the previous realtime recorded data are cleared. Therefore, make
sure to save important data before starting the realtime recording. For the operating procedures on saving
the data, see 11.6 “Saving/Loading Waveform Data.” To save the data, refer to Section 11.6 “Saving/
Loading Waveform Data” and save the data accordingly.
