UDX-P01 and New UDX-P02 Prescale Trigger Heads

Why I can see a low-level divided kick-out signals from the input of the UDX-P01 prescaler head?

The UDX-P01 prescaler head may have this phenomenon. As a rule it is a small kick-out having a frequency on the input trigger signal divided by eight. If this kick-out has an influence on the test result you should use a trigger signal that is independent on the tested signal.
