2. Confirm the trigger system is within time-accuracy limits for pulse-glitch or
pulse-width triggering (time range ≤500 ns):
a. Display the test signal: Set the output of the sine wave generator for a
100 MHz, five-division sine wave on screen. Press SET LEVEL TO
50%.
b. Set the trigger mode: Press TRIGGER MENU. Now press the
main-menu button Mode & Holdoff; then press the side-menu button
Normal.
c. Set upper and lower limits that ensure triggering: See Figure 1–16.
H Press the main-menu button Type; then repeatedly press the same
button until Pulse is highlighted in the menu that pops up.
H Press the main-menu button Class; then repeatedly press the same
button until Width is highlighted in the menu that pops up.
H Press the main-menu button Trig When; then press the side-menu
button Within Limits.
H Press the side-menu button Upper Limit. Use the keyboard to set
the upper limit to 10 ns: press 10, then SHIFT, then n, and ENTER.
H Press the side-menu button Lower Limit. Use the keypad to set the
lower limit to 2 ns.
d. Change limits until triggering stops:
