Trigger Mode:
[Single]
When the Trigger Mode is [Single], measurement continues until the specified
number of waveform samples is acquired.
*1. Awaiting a trigger until the specified number of samples is acquired.
*2. Measurement finishes automatically when the specified number of samples is ac-
quired.
*3. If you press the STOP key twice to abort before the specified number of waveform
samples is acquired, no waveform data is retained.

Trigger Mode:
[Continuous]
When the Trigger Mode setting is [Continuous], measurement continues for the
specified number of waveform samples to be averaged, after which operations
such as on-screen display and measurement repeat until you press the STOP
key.
*1. With simple averaging, a new average value is calculated each time the specified num-
ber of samples is acquired.
*2. With exponential averaging, the previous average value is applied to the next measure-
ment series when the next average is calculated.
*3. If you press the STOP key twice to abort measurement before the specified number of
waveform samples is acquired, no waveform data is retained. To retain waveform data,
press the STOP key once and wait until measurement finishes.
Trigger Mode:
[Auto]
When the Trigger Mode setting is [Auto] after you press the START key, data is
acquired after a fixed time even if no trigger criteria are met. In this case,
because the signal is asynchronous, averaging data has no meaning.
