About the Recording Interval
• Select the data acquisition interval to suit your measurement objectives.
• Note that shorter recording intervals restrict the maximum recording time.
• The minimum recording interval depends on the input unit (channels),
and wh
ether burn-out detection is enabled.
With burn-out detection (Burn Out) disabled (Off)
When channels 1 to 15 of UNIT1 are selected for measurement: 10 ms
When channels 1 to 15 of UNIT2 are selected for measurement: 20 ms
When channels 1 to 15 of UNIT3 and UNIT4 are selected for measure-
ment: 50 ms
With burn-out detection (Burn Out) enabled (On)
When channels 1 to 15 of UNIT1 are selected for measurement: 20 ms
When channels 1 to 15 of UNIT2 are selected for measurement: 50 ms
When channels 1 to 15 of UNIT3 and UNIT4 are selected for measure-
ment: 100 ms
See:"Chapter 11 Specifications" (p. 225)
• Some waveform peaks may not be displayable with certain interval set-
tings.
For example, when the [Interval] is 1 s a
nd the [Time/DIV] (time base) is
5 s/DIV.

• With the 50 or 60 Hz digital filter setting, longer recording intervals pro-
duce lower cut-off frequencies and better noise suppression (p. 73).
• The recording interval cannot be changed while measuring. Stop mea-
surement before setting.
During Normal Recording ([Co
nt] disabled (Off), and [Repeat] enabled
(On))
After a recording length has elapsed, some “dead time” is needed for inter-
nal processing before recording can resume. No measurement occurs dur-
ing the dead time. So to avoid information loss, split data into files at a
specifie
d interval by enabling continuous recording ([Repeat]), and select-
ing [
Split Save] for auto saving.
