Turn the TIME/DIV knob to set the T/div.
Note
If the TIME/DIV knob is turned while the waveform acquisition is stopped, the new T/div value
is displayed inside the parentheses at the upper right corner of the screen. The new T/div
value becomes valid the next time waveform acquisition is started.
1 ns/div to 50 s/div in 1-2-5 steps (when the record length is 10 kW or more)
1 ns/div to 5 s/div in 1-2-5 steps (when the record length is 1 kW)
The maximum sample rate when repetitive sampling is OFF (see section 7.4) is 1 GS/s
(2 GS/s when interleave mode is ON). In repetitive sampling mode, data can be
sampled at 2 GS/s (5 GS/s when interleave mode is ON) to 100 GS/s. However, the
time axis settings that allow repetitive sampling mode vary depending on the model and
settings such as the record length. For details, see appendix 1.
Note
When you change the T/div setting, repetitive sampling mode may be automatically enabled
even when repetitive sampling is set to OFF (see appendix 1).
Under the following conditions, roll mode display is enabled for the T/div settings listed
below.
• Acquisition mode is set to a mode other than averaging.
• Acquisition count is set to infinite.
• The trigger mode is set to auto, auto level, or single.
