■ Frequency Division
Duty ratio: 50%
(Duty of the output pulse is 50%)
When division is set, the duty ratio of the output signal is 50%.
However, if the division ratio is 1/1 (no division), the M2PDU outputs a signal equivalent to the input signal, so the duty of the output pulse may not be 50%.
(Example: When the duty of the input signal is 40% and the division ratio is set to 1/1 (no division), the duty of the output signal is approximately 40%.)
Setting division ratio: rotary switch (front)
In the range of 1/1 to 1/6400, division ratio can be set arbitrarily with the combinations of the switches.
