Advanced Features
The A sweep
is
unaffected, and a capture
is
initiated by a
valid A trigger after an arm. The B sweep, however, can
only begin a capture on the 20th valid B trigger after arm.
Note:
If
'A
divided
by
N'
is selected then 'B
delay
by
N'
cannot
be used,
and
vice-versa.
In addition, 'A
divided
by
N'
cannot
be used
with
'Inde-
pendent'
(see below).

The B sweep

is
initiated by a
valid B trigger after arm. The A sweep begins its capture
500µ.s
(0.5ms) after the receipt
of
a valid A trigger after

of
events prior to
the trigger point.
