Cymometer
►
It is a 6-digit cymometer. The cymometer can measure frequencies from
2Hz to the full bandwidth. Only if the measured channel has triggering
signal and in Edge mode, it can measure frequency correctly. In the Single
trigger mode, it is a one channel cymometer and it can only measure the
frequency of the triggering channel. In the ALT trigger mode, it is a two
channel cymometer and it can measure the frequency of two channels. The
cymometer is displayed at the right bottom of the screen.
