Changes to normal mode,
even when envelope mode
has been set.
*1 The displayed record length and acquisition-memory record length are equivalent.
*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 Regardless of the "
Rep
" setting, repetitive sampling is not used with 1MW maximum displayable record length.
(A "
Rep
" setting of "
ON
" is ineffective.)
*5 This column is inapplicable on DL1520L.
*6 CH2 is OFF in the case of DL1520L.
