Figure 1-40: Sync Duty Cycle Test: One-Div Neg Pulse Waveform
Turn the pulse generator PULSE DURATION variable control to
adjust the negative pulse so the oscilloscope CH1 – Width
measurement displays 400ns +/–10 ns.
Turn the HORIZONTAL SCALE knob to set the oscilloscope time
base to 5 s/div.
Turn the pulse generator PERIOD variable control to adjust the
period until the oscilloscope CH1 Period measurement reads
21.000 s –25/+50 ns (See Figure 1-41). 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.
