Period and Frequency
3-6
1, Set SEC/DIV and, if necessary, X10 MAG to spread one cycle over as wide
a span as
possible.
2. Turn on t.t or 1/t.t and align the cursors with identical, fast-slewing points
on consecutive
cycles, such as zero-crossings.
With the
available Counter-Timer-Trigger (CIT) you can measure period and
frequency more
accurately and with less effort.
