Triggered Delta-Delay-Time
Measurements
The available Counter/Timer/Trigger (CTT) 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 At or 1/At:
RUN AFT DLY
B Sweep runs immediately after the set delay.
Without At or 1/At:
TRIG AFT DLY
B Sweep runs at the first trigger after the set delay.
With At or 1/At:
TRIG AFT DLY and TRIG A DLY {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 deiay.
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 DLY and TRIG A DLY.
With At or 1/At and TRIG AFT DLY or TRIG A DLY, the upper Mode button selects
the TRIG AFT DLY and TRIG A DLY mode, where Siope and Levei are common for
both delays.
