H Press SHIFT; then press DELAYED TRIG. Press the main-menu
button Level.
H Press the side-menu button SET TO 50%.
CHECK that a stable trigger is obtained for the test waveform for
both the positive and negative slopes of the waveform. Use the
TRIGGER LEVEL knob to stabilize the Main trigger. Use the
general purpose knob to stabilize the Delayed trigger. Press the
main-menu button Slope; then use the side menu to switch between
trigger slopes. See Figure 1–18 on page 1–65.
H Enter pass/fail result for delayed trigger on the test record.
H Leave the Delayed trigger system triggered on the positive slope of
the waveform before continuing to the next step. Also, return to the
main time base: Press HORIZONTAL MENU; then press the
main-menu button Time Base. Press the side-menu button Main
Only.
H Press CLEAR MENU.
3. Confirm the AUX Trigger input:
a. Display the test signal:
H Remove the 10X attenuator and reconnect the cable to CH 1.
H Set the test signal amplitude for about 2.5 divisions on screen.
H Now fine adjust the generator output until the CH 1 Amplitude
readout indicates the amplitude is 250 mV. (Readout may fluctuate
around 250 mV).
b. Check the AUX trigger source for stable triggering at limits: Do the
following in the order listed.
H Use the definition for stable trigger from step 2.
H Press TRIGGER MENU; then press the main-menu button Source.
H Press the side-menu button –more– until the side-menu label
DC Aux appears; then press DC Aux.
H Press SET LEVEL TO 50%. CHECK that a stable trigger is
obtained for the test waveform on both the positive and negative
slopes. Press the main-menu button Slope; then use the side menu to
switch between trigger slopes. Use the TRIGGER LEVEL knob to
stabilize the trigger if required.
H Enter the pass/fail result on the test record.
