Clock Data Recovery and Multiplexer

 

connected to 

N4903B Serial BERT

Power Requirements

Connections of the N4877A

The N4877A is controlled via USB or LAN. When 
controlling the N4877A interactively with the N4877A 
remote GUI, then the preferred interface is USB. The 
N4877A Remote GUI can be installed on any Windows 
PC that fulfills the system requirements.

This document assumes that the N4877A remote GUI 
is to be installed on a N4903B Serial BERT and that 
the N4877A is being controlled interactively using the 
USB interface.

In a regular test setup the 

Data In

 connectors of the 

N4877A will be connected to the device under test 
and the 

Recovered Clock Out

 connector will be 

connected to the Error Detector's 

Clock Input

 

connector. 

In some applications, when the serial data rate is 
above the Error Detector's maximum data rate, the 
Error Detector's 

Data Input

 will be connected to the 

Demux Data Out

 connector of the N4877A.

For bringing up the N4877A together with the
N4903B, connect the Pattern Generator's 

Data Out

 to the N4877A 

Data In

.  

All data and clock input and output connectors 
of the PG that are not used in your test setup 
must be terminated with 50 Ohm.

The instrument can operate from any single-phase 
AC power source supplying 100 – 240 V in the 
frequency range from 50 – 60 Hz.
The maximum allowed voltage fluctuation is 10%.
The maximum power consumption is 90 VA.
The power supply automatically adapts to the
applied AC power (Auto Selection) and monitors
the AC power range.

The mains plug may only be inserted in a socket 
outlet that provides protective earth contact. Any 
interruption of the protective earth contact inside or
outside the instrument makes any operation of the 
instrument dangerous. Intentional interruption is 
prohibited.

Ventilation Requirements

Do not cover the ventilation holes.

Make sure that there is adequate clearance of 50 mm (2 in) at the rear and right side 

of the instrument to ensure adequate air flow. If the air flow is restricted, the internal 

operating temperature will be higher, reducing the instrument's reliability.

For the complete content of your delivery 
please refer to the Box Contents List.

In addition, the box will contain an  
installation media, 4 x 50 Ohm termination 
resistors, 2 x 3.5mm/2.4mm adapter and 
Certification of Calibration 
(Uk6 report) RoHS.
