Capture the Single Signal

Example 4: Analyze the Details of a Signal

Observe the Signal Containing Noises

If the signal is interfered by the noise, the noise may cause a failure in the circuit. For
the analyzing of the noise in detail, please operate the instrument according to the
following steps:

1.

Press the

ACQUIRE

button to display the

ACQU MODE

menu.

2.

Press the

F2

menu selection button and choose

Peak Detect

.

In this case, the screen display contains the wave form of a random noise. Especially
when the time base is set as Low Speed, then noise peak and burr contained in the
signal can be observed with the peak detection (See Fig.68).
