IM DL850E-01EN
• When the main waveform acquisition mode is Average, dual capturing cannot be executed.
• Dual capturing action cannot be executed during hard disk recording.
• During dual capturing, the DL850E/DL850EV may respond more slowly to operations.
• Use the internal clock as the time base when you perform dual capturing. You cannot perform dual
capturing when an external clock is being used.
• When you perform dual capturing, all the previous waveform data is deleted.
• Dual capturing cannot be performed on X-Y waveforms.
• The accumulate function cannot be used.
• Computation cannot be performed on captured waveforms.
• When the automated measurement of waveform parameters is enabled, the time it takes for the DL850E/
DL850EV to enter the trigger-ready state may become longer after a captured waveform is acquired.
• The history feature cannot be used on waveform data acquired through dual capturing.
Waveform Acquisition (START/STOP)
When you start waveform acquisition, the DL850E/DL850EV stores waveform data to the acquisition memory
and updates the displayed waveforms each time it triggers. The acquisition memory is divided into many areas
based on the set record length, and the maximum number of acquirable waveforms are stored in the memory.
You can recall past waveforms that are stored in the memory by using the history feature when waveform
acquisition is stopped.
DL850E/DL850EV Operation When the Acquisition Mode Is Set to Averaging
• Averaging stops when you stop acquisition.
• If you start acquisition again, averaging starts from the beginning.
START/STOP Key Operations during Accumulation
• Accumulation stops when you stop waveform acquisition.
• When you start acquisition again, the displayed waveforms up to that point are cleared, and accumulation
restarts from the beginning.
The START/STOP Key Is Disabled:
• When the DL850E/DL850EV is in remote mode.
• When the DL850E/DL850EV is printing to a printer, when it is being set up automatically, or when it is
accessing a storage medium.
• If you change the waveform acquisition conditions and start waveform acquisition, the past data stored in
the acquisition memory is cleared.
• You can use the snapshot feature to retain the displayed waveform on the screen. This feature allows you
to update the display without having to stop waveform acquisition.
• Regardless of the trigger settings, you can make the DL850E/DL850EV trigger by pressing the MANUAL
TRIG key on the front panel.
