Operation
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.
