6. Set up the function generator as follows:
Frequency 900 kHz
Amplitude 8.3 V
Burst Mode yes
Burst Count 1
Burst Rate 100 Hz
Burst Phase -90 Degrees
7. Set the oscilloscope for 0.5 V/DIV @ 0.5 µs/DIV.
8. Trigger the waveform on channel 2.
9. Adjust the amplitude of the function generator to produce a 3 VP-P triangle wave.
See Figure 6.
10. Set the oscilloscope for 1.0 V/DIV @ 5.0 ms/DIV.
11. Trigger the waveform on Channel 1.
12. Check that the peak voltage is greater than 5.7 V and decays to less than 1.0 V
between pulses. See Figure 6. Record the peak value for later use.
13. Adjust the function generator output so the peak voltage is 6 V.
14. Set the scope for 1.0 ms/DIV and trigger waveform.
15. Check the amplitude after 3.0 ms from the waveform peak, the voltage amplitude is
2.4 V +0.5/-0.8 (1.6 V to 2.9 V). (See Figure 3-5(C).)
16. Re-adjust the function generator output to obtain the value recorded in step 12.
17. Set the scope for 5.0 ms/DIV.
18. Turn the inductive pickup so that "SPARK PLUG SIDE" points along the wire
connected to the LOW output of the function generator. Check that the waveform is
less than 2 V.
