Tektronix 2465A User Manual

Operation
8- Trigger Operation
Use the B Trigger to eliminate jitter in B-Sweep displays. With the available
Counter-Timer-Trigger (Crr), the B Trigger locks a delay-time or delta-delay-time
measurement to the signal, so any variations are tracked automatically. However,
without the
crr, the B Trigger obscures delay or delta-delay measurements and the
readout
includes a question mark.
Distinguish RUN AFT DL Y and TRIG AFT DL Y
With RUN AFT DL Y mode, the d REF OR DL Y POS and d controls adjust
the
delay-time or delta-delay-time. The intensified zones on the A-Sweep trace
move
continuously as the controls are adjusted. If the B-Trigger mode is TRIG
AFT DL Y and a signal triggers the B Sweep, the delay times and intensified
zones jump
to successive B-Trigger pOints as delay time is adjusted. With TRIG
AFT DL Y, the actual delay time is controlled by the signal, as enabled by the A
Sweep and the
d REF and d settings.
Setting the B Trigger
1. When the B SWP indicator is on, press A/B/TRIG (A/B/MENU with
CT7)
to illuminate a B-Trigger Mode indicator. (If B-Trigger mode is not
RUN AFT DL Y, a B-Trigger Mode indicator will be on when the B SWP
indicator is on.)
2. Select TRIG AFT DL Y Mode.
3. Set SOURCE, COUPLING, SLOPE, INIT@50%, and LEVEL controls as
required.
Changing the A Trigger while B Trigger is Active
2-14
1. Press and hold A/B/TRIG (A/B/MENU with CT7) while adjusting
SOURCE, COUPLING, SLOPE, INIT@50%, and LEVEL controls for the
A Trigger.
2. Alternatively, choose RUN AFT DLY B-Trigger mode and momentarily
press
A/B/TRIG (or A/B/MENU), then adjust A Trigger. With RUN AFT
DL Y B-Trigger mode
or SGL SEQ A-Trigger mode (or an active crr
function that uses the B Trigger), the trigger controls alternate between
A Trigger and B Trigger each time
A/B/TRIG (or A/B/MENU) is
momentarily pressed.
