43.1. How to set sampling system

Sampling system is to set sample rate, storage depth and filter. Different sampling setting will result in different

measure results. In the same storage depth, the higher sample rate set, the shorter the continuance time for

signal will be. If the sample rate set too low, narrower pulse signal may get lost. So the sample rate and

storage depth should be set correctly according to the actual measuring signal. Press “E (ACQU)”and display

menu as the Fig. 75:
