Figure 1–39: Sync Duty Cycle Test: One-Div Neg Pulse Waveform
H Turn the pulse generator PULSE DURATION variable control to
adjust the negative pulse so the oscilloscope’s CH1 – Width
measurement displays 400ns +/–10 ns.
H Turn the HORIZONTAL SCALE knob to set the oscilloscope time
base to 5ms/div.
H Turn the pulse generator PERIOD variable control to adjust the
period until the oscilloscope CH1 Period measurement reads
21.000ms –25/+50 ns. See Figure 1–40. Read note shown below.
NOTE. The pulse duration and period adjustments are critical in making this
measurement. If the pulse duration and/or the duty cycle are not stable, the
FLEXFMT function may not function. You must take care when making these
adjustments.
