Duty Cycle Measurements
Duty cycle (or duty factor) is the percentage of time a
signal is above or below a trigger level in one cycle
(Figure 9). The duty cycle mode is optimized to measure
the on or off time of logic and switching signals. Systems
such as electronic fuel injection systems and switching
power supplies are controlled by pulses that have
different widths, which can be measured by a duty cycle
measurement.
To measure duty cycle, set up the Product to measure
frequency. Then push G a second time. As with the
frequency function, push E to change the slope for
the counter.
For 5-V logic signals, use the 6-V dc range. For 12-V
switching signals in automobiles, use the 60 V dc range.
For sine waves, use the lowest range that does not result
in multiple triggers. (Normally, a distortion-free signal can
be up to 10x the amplitude of the selected voltage range.)
If a duty cycle measurement is unstable, push MIN MAX
and then scroll to the AVG (average) display.
