At Least One of CH3, CH4 is ON

Rep: "ON"
Rep: "OFF"
Rep: "ON"
Rep: "OFF"
*1 The displayed record length given in ( ) refers to the record length stored in the acquisition memory.
Only when the trigger mode is auto or auto level, data of a record length given in ( ) is stored.
In case where no value in ( ) is given, the displayed record length and the record length stored in the acquisition memory
are the same.
*2 The sample rate given in ( ) for the envelope mode is the rate at which data are acquired after having been sampled at
100MS/s and having taken the minimum and maximum values.
*3 In the envelope mode, the minimum / maximum values are displayed in a pair.
*4 For the setting enclosed by the bold line, repetitive sampling mode is active.
*5 CH2 is ON in the case of DL1520.
*6 CH2 is OFF in the case of DL1520.
Rep: Repetitive sampling mode
CH3, CH4 are Both OFF
*6
When Mode other than Envelope Mode is Active
When Envelope Mode
is Active
trigger mode : auto, auto level, normal, single short
hysterisys : OFF
Changes to normal mode,
even when envelope mode
has been set.
