FIG 5. PULSE, RAMP, AND SKEWED SINE WAVE GENERATION
C. If both a specific pulse width and repetition rate (specific rise time and fall
time for ramp wave), :are required, The waveform may be obtained as
follows:
a. Adjust the shorter duration portion of the waveform(pulse width for pulse,
fall time for ramp waves)with the frequency controls FREQ. dial and
RANGE switch.
b. Adjust the longer duration portion of the waveform(rest time for pulses,
rise time for ramp waves)with the SYMMETRY control.
D. If a specific pulse width (specific fall time for ramp wave)is not critical, but a
specific repetition rate is required, the desired waveform may be obtained as
follows;
a. Observe the oscilloscope and adjust the SYMMETRY control to obtain
the approximate desired pulse width vs. rest time ratio(rise time vs. fall
time ratio for ramp waves).
b. Adjust the repetition rate with the frequency controls FREQ. dial and
RANGE switch. the frequency controls affect both the pulse width and
repetition rate.
