Triggered Delta-Delay-Time Measurements
The available Counter-Timer-Trigger
(CIT)
directly measures intervals defined by
the B-Sweep delays and B Trigger. B Trigger with
At and 1/At can have different
sources, levels, and slopes for the pair of B-sweeps. Repeatedly pressing the lower
Mode button selects the following sequence
of
B-Trigger modes with the noted
characteristics:
With
or without
Llt
or 1/Llt:
RUN
AFT
DLY
B Sweep runs immediately after the set delay.
Without
Llt
or 1/Llt:
TRIG
AFT
DLY
B Sweep runs at the first trigger after the set delay.
With
Llt
or 1/Llt:
TRIG
AFT
DL
Y
and
TRIG
A
DL
Y (both indicators on)
SLOPE and LEVEL settings for triggering at A REF delay and A delay
are common.
TRIG
A
DLY
SLOPE and LEVEL for A delay can be set independent of the setting for
A
REF
delay.
TRIG
AFT
DLY
SLOPE and LEVEL for A
REF
can
be
set independent of the setting for
A delay.
TRIG
A
DLY
Repeated operation of the lower Mode button toggles between TRIG
AFT DL Y and TRIG A DL
Y.
With At or 1/At and TRIG AFT DL Y or TRIG A DL
Y,
the upper Mode button selects
the
TRIG AFT DL Y and TRIG A
DL
Y mode, where Slope and Level are common for
both delays.
