Explanation
Normally, the display is updated every time the trigger is activated making it difficult to
capture transient conditions such as sudden distortion of waveforms. By using the
accumulate function, the waveform display of the acquired data remains on the screen
for the specified time.
Accumulate Mode
Persist: Persistence mode. Accumulates in red. Displayed for the specified time period
by gradually lowering the brightness.
Accumulate Period: Count
When using persistence mode, set the number of times to accumulate the waveform in
the range of 2 to 128 (in 2
n
steps). If you select Infinite, the accumulation is carried out
infinitely. The default value is 16.
Notes When Using Accumulation
• Automated measurement of waveform parameters and GO/NO-GO determination are
performed on the newest waveform.
• When printing accumulated waveforms using the built-in printer, they are printed using
two tones.
• If the waveform acquisition is forcibly stopped by pressing START/STOP, the
accumulation is temporarily suspended. When the acquisition is restarted, the display
is cleared and accumulation continues.
• You cannot change the parameters on the HISTORY menu when accumulating
waveforms on the display.
• Accumulated display is not possible in roll mode display.
• When you turn OFF the accumulate mode, accumulated waveforms are cleared. To
display the acquired waveforms again, specify the record number on the HISTORY
menu.
• If you display the waveforms again by setting the accumulate mode to Persist, the
accumulated waveforms are not cleared. To clear them, execute CLEAR TRACE.
• Even if you change the display format during accumulated display, the waveforms that
are already displayed accumulated are not cleared. To clear them, execute CLEAR
TRACE.
Clearing Accumulated Waveforms
You can clear accumulated waveforms by pressing the CLEAR TRACE key.
