6.3 Setting Conditions for Error Detection
The conditions for detecting bit errors must be set.
Signal input terminal
The signal input terminals for the ED are the ED1, ED2, ED3, and ED4
Data
In connectors and Data In connector on the panel.
The ED1 connector supports ED_Ch1 and the ED2 connector supports
ED_Ch2.
The ED1 connector corresponds to ED_Ch1, and the ED2 connector
corresponds to ED_Ch2.
The ED1, ED2, ED3, and ED4 signal input terminals are AC couplings.
The block diagram for input terminal is as shown below.

CAUTION
●
The impedance of the electrical input connector is 50 Ω .
Measurement may not be performed correctly if a
coaxial cable with another impedance is used.
●
Do not apply a DC voltage of more than 1 V to the Data
In connectors. Otherwise, the internal circuits may be
damaged.
