SGL(L) (Single long mode) : for DL1540
This mode is the same as the aboved mentioned SGL(S) mode, except that the record length
here is longer. The maximum record length is 120 K words.
For more details about the relation between time axis setting, sample rate and record length,
refer to Appendix 2.
N-SGL (Single (N) mode) : for DL1520L/DL1540/DL1540L
Each time the trigger condition becomes true after the START/STOP key has been pressed,
acquisition is performed the specified number of times. The waveforms will be displayed
after acquisition stops.
If the START/STOP key is pressed again before acquisition has been completed the
specified number of times, acquisition stops immediately. In this case, all the waveform data
which has been acquired thus far is valid and can be displayed.
This trigger mode can only be used in real time sampling mode.
For setting the number of repetitions, refer to page 7-7.
Points to note when setting the trigger mode
• If single short mode or single mode is selected with a T/div setting which enables
repetitive time sampling mode, acquisition will stop after it has been repeated the
specified number times.
• If trigger mode is changed while acquisition is stopped (i.e. while the START indicator is
not lit), acquisition starts automatically.
• For DL1520L/DL1540/1540L if acquisition is interrupted in single (N) mode, only the
waveforms which have been acquired completely are displayed.
• For DL1520L/DL1540/1540L if the history memory function is set ON or if the
acquisition mode is set to averaging, all single mode triggering cannot be done.
• For DL1520L/DL1540/1540L if single long mode or single (N) mode is selected,
repetitive sampling cannot be done.
• When the record length (maximum displayable record length) is 400 K/1 MW for
DL1520L, or 400 K/1 MW/2 MW for DL1540L, single mode is the only mode available.
