Time axis setting range
T/div can be set within the range of 5 ns/div to 50 s/div (in multiples of 1, 2 and 5)
The relationship between sampling mode and display mode
Sampling mode and display mode change as follows according to the T/div setting. For a
detailed description of sampling mode and display mode, refer to page 1-5 and 1-6.
• If maximum displayable record length is set to 1 K (DL1520L/DL1540L)
Time-axis setting Sampling mode Display mode *1
50 s to 50 ms/div Real-time Roll mode
20 ms to 1 µ s/div Real-time Update mode
500 ns to 100 ns/div Real-time/repetitive *2 Update mode
50 ns to 5 ns/div Repetitive Update mode
• If maximum displayable record length is set to 10 K or 100 K (DL1520L/DL1540L), or
when DL1520/DL1540 is used
Time-axis setting Sampling mode Display mode *1
50 s to 50 ms/div Real-time Roll mode
20 ms to 10 µ s/div Real-time Update mode
5 µ s to 100 ns/div Real-time/repetitive *2 Update mode
50 ns to 5 ns/div Repetitive Update mode
• If maximum displayable record length is set to 400 K (available only if trigger mode is
“single”) (DL1520L/DL1540L)
Time-axis setting Sampling mode Display mode *1
50 s to 200 ms/div Real-time Roll mode
100 ms to 100 ns/div Real-time Update mode
• If maximum displayable record length is set to 1 M (available only if trigger mode is
“single” and the only displayed channel is CH1 for DL1520L.) (DL1520L/DL1540L)
Time-axis setting Sampling mode Display mode *1
50 s to 500 ms/div Real-time Roll mode
200 ms to 100 ns/div Real-time Update mode
• If maximum displayable record length is set to 2 M (available if trigger mode is “single”
and display channel is 1 or 2) (DL1540L)
Time-axis setting Sampling mode Display mode *1
50 s to 1 s/div Real-time Roll mode
500 ms to 100 ns/div Real-time Update mode
*1 Indicates the display mode which is in effect when the trigger mode is auto mode or auto level
mode and hysterisis is set off. For a description of how to set the trigger mode, refer to 6.8
“Setting the Trigger Mode” (page 6-12).
*2 Either real-time or repetitive mode is possible. For a description of how to switch modes, refer
to 7.1 “Selecting Acquisition Mode, Sampling Mode and Record Length” (page 7-1).
