• To exit the menu during operation, press ESC
located above the soft keys.

keyboard or a USB mouse, see section 4.3.
1. Press ACQ . The ACQ menu appears.
2. Press the Repetitive soft key to select ON or OFF.
Explanation
You can turn repetitive sampling ON or OFF. When repetitive sampling mode is turned
ON, the sample rate is set greater than or equal to 1 GS/s (greater than or equal to 2
GS/s when interleave mode is ON) for certain T/div settings.
When repetitive sampling is turned OFF, sampling is performed at a rate of up to 500
MS/s (or 1 GS/s when interleave mode is ON). When the number of displayed data
points is less than 500, data is interpolated and displayed.
However, even when repetitive sampling is turned OFF, repetitive sampling may be
performed depending on the time axis setting.
Possible T/div Settings for Performing Repetitive Sampling
If repetitive sampling mode is turned ON and the time axis is set according to the table
below, repetitive sampling is performed. The T/div settings for performing repetitive
sampling vary depending on the specified record length.
Record Length T/div
1 kWord 1 ns/div to 100 ns/div (1 ns/div to 50 ns/div)
10 kWord 1 ns/div to 1 µ s/div (1 ns/div to 500 ns/div)
50 kWord 1 ns/div to 5 µ s/div (1 ns/div to 2 µ s/div)
100 kWord 1 ns/div to 10 µ s/div (1 ns/div to 5 µ s/div)
250 kWord 1 ns/div to 20 µ s/div (1 ns/div to 10 µ s/div)
500 kWord 1 ns/div to 50 µ s/div (1 ns/div to 20 µ s/div)
1 MWord 1 ns/div to 100 µ s/div (1 ns/div to 50 µ s/div)
2 MWord 1 ns/div to 200 µ s/div (1 ns/div to 100 µ s/div)
4 MWord 1 ns/div to 500 µ s/div (1 ns/div to 200 µ s/div)
8 MWord –(1 ns/div to 500 µ s/div)
• The selectable record length varies depending on the model. For details, see section 7.2.
• The values inside the parentheses are the selectable ranges when interleave mode is ON.
Notes on Repetitive Sampling
When repetitive sampling is in progress, waveform acquisition using the Single(N) trigger
mode is not possible.
