Delayed Triggering
TDS 420A, TDS 430A, TDS 460A & TDS 510A User Manual
3–13
By pressing Intensified
(side), you can display an intensified zone that shows
where the delayed timebase record may occur (a valid delay trigger event
must be received) relative to the main trigger on the main timebase. For
Delayed Triggerable After mode, the start of the intensified zone corresponds
to the possible start point of the delayed timebase record. The end of the
zone continues to the end of main timebase, since a delayed time base record
may be triggered at any point after the delay time elapses.
To learn how to define the intensity level of the normal and intensified
waveform, see Display Modes on page 3–17.
Now you need to bring up the Delayed Trigger menu so you can define the
delayed trigger event.
4. On a TDS 400A, press SHIFT DELAYED TRIG
➞ Delay by (main) ➞
Triggerable After Time, Events, or Ext clks
(side) (Figure 3–6).
5. On the TDS 510A, press SHIFT DELAYED TRIG
➞ Delay by (main) ➞
Triggerable After Time, Events, or Events/Time

6. Enter the delay time or events using the general purpose knob or the keypad.
Hint: You can go directly to the Delayed Trigger menu (see steps 4 and 5).
By selecting either Triggerable After Time, Events, or Events/Time, the
oscilloscope automatically switches to Delayed Triggerable in the Horizontal
menu. If you wish to leave Delayed Triggerable, you still need to display the
Horizontal menu.
The Source menu lets you select which input is the delayed trigger source.
