Parameter Description Definition Notes
Period Period of a cyclic signal
measured as time between
every other pair of 50%
crossings. Starting with first
transition after left cursor,
period is measured for each
transition pair, with values
averaged to give final result. f

leading edges found, Mf
number of trailing edges

rising edge i crosses the x%
