4.1
Starting and Stopping Acquisition
1.
Press the
START/STOP key
to start/stop waveform acquisitioning.
2.
In case the indicator located at the upper left of the
START/STOP
key
is lit, waveform acquisition is in progress.
3.
In case the indicator located at the upper left of the
START/STOP
key
is not lit, waveform acquisition is not in progress. In the upper
left corner of the screen, “Stopped” appears.
Explanation
Operation when averaging mode is selected as the acquisition mode
Averaging stops when acquisition is stopped, and resumes when acquisition is restarted.
Operation during display of accumulated waveforms
Accumulated display stops temporarily when acquisition is stopped. When measurement is
restarted, the accumulated display is reset and accumulation starts.
The START/STOP key is not operative in the following cases
• When remote state is active (i.e. the REMOTE indicator is lit);
• When a short or long copy is being output to the built-in printer;
• When the floppy disk is being accessed (e.g. when data is being saved to it). (If
acquisition is in progress, access to the floppy disk starts after acquisition is stopped.);
• When calibration, auto set-up or initialization is in progress.
Operation in combination with external clock
When the external clock is being used and you start acquisition, the error messages “Ext
clock too slow” or “Ext clock too fast” might appear.
Note
If the START/STOP key is pressed to start acquisition while acquisition data (ACQ data) loaded from a
floppy are being displayed, the acquisition data will disappear from the screen. It is possible to retain the
waveform on screen by stopping acquisition only for the channel corresponding to the trace No. of the
waveform. For a description of this operation, refer to page 12-6.
For details regarding the external clock settings, refer to page 5-8.
