1-Cycle Mode (1-Cycle Mode)
Instead of automatically measuring the measurement time period specified by Time Range1 and Time Range2,
you can automatically measure the first period after Time Range1.
The method of determining the period is the same as the method for determining the Period measurement item.
In this mode, after the period is determined, the values of the measurement items related to voltage and area
are computed. This mode is effective for measurement items, such as Rms or Avg, that may result in errors
depending on the measurement time period setting.
The measurements of time axis items and X-Y areas are not affected.
• OFF: 1-cycle mode is disabled.
• ON: 1-cycle mode is enabled.

If the space between Time Range1 and Time Range2 is less than one period, “*****” is displayed for the
measured value.
Notes about Automated Measurement of Waveform Parameters
• Measurements cannot be made on a snapshot waveform or an accumulated waveform that is not the most
recent waveform.
• When an item is impossible to measure its measured value is displayed as ‘*****’.
• When the measurement range exceeds 100 Mpoint
• When the delay measurement mode is Degree and the trigger source is set to the reference of the
reference waveform
• The DL850E/DL850EV may not measure correctly if the waveform amplitude is small.
• If there are two or more waveform periods within the measurement time period, the time-axis parameters are
measured on the first period.
• When automated measurement is performed on a waveform that has been recorded to a hard disk, extra time
will be required for hard disk access.
• Automated measurement may require additional time depending on settings such as the memory length, the
number of measurement items, and the input waveform. During automated measurement, appears in the
center of the screen.
• To cancel automated measurement, set Mode to OFF. Measurement stops immediately.
• Only the Max and Min items can be measured for FFT waveforms. Only the overall rms power spectrum value
can be measured.
• While the dual capture window is displayed, you can perform automated measurements of waveform
parameters on captured waveforms.
To perform automated measurement of the waveform parameters in the main window, turn the display of the
dual capture window off.
• The automated measurement results of captured waveforms are displayed in italics.
