Difference Between Dead Times During Normal and Memory Division
Recording
When both printer recording (Auto Print) and Auto Save are set for continuous
triggering [Repeat]
Dead Times
Times during which sampling is inhibited due to internal processing, printing or saving

Anomalous phenomena occurring during dead times are not detected.

Recording
Length
Dead Times
The waveform data of each recording length is recorded in one block.
When recording with Memory Division, dead time is shorter than with normal recording.
• The dead time (time where no sampling occurs between blocks) of memory division is as follows.
5
μ
s/div to 20
μ
s/div: 1 to 8 samples
Time axis slower than 50
μ
s/div: 1 samples
Note: Dead time lengthens during calculation of a number of values or when the time axis is 5 to
20
μ
s/div and tracking waveform display is [On] .
• When measuring with an 8970 FREQ Unit, dead time is approximately 230 ms. When measuring
in integral value ( [Count] ) mode, there are cases when the last data in the previous block
remains in the first part of the block.
• When tracking waveform display is [Off] , the roll mode function cannot be used, even when roll
mode is enabled (not Off).
• When triggering occurs very often, pressing the STOP key may not stop measurement until
enough data has been acquired to fill the blocks specified for use.
Auto Save and Auto Print for Memory Division Recording
Measuring conditions Auto Save and Auto Print
With Numerical calcula-
tion ON Auto Save and Auto Print are performed every time one block is measured. When
Tracking wave display is ON, Waveform is also displayed.
When time axis is 5 to 20
μ
s/div with Tracking wave
display ON.
Auto Save, Auto Print and Waveform Display are performed every time one block is
measured.
When time axis is 5 to 20
μ
s/div with Tracking wave
display OFF.
Auto Save and Auto Print are performed after all blocks are measured.
Other than above
Auto Save and Auto Print are performed simultaneously with measuring. When
Tracking wave display is ON, Waveform is also displayed.
