Installing the Keysight N4877A
Inspect Shipment
Check if the Keysight N4877A shipping container
contains the following standard deliverables:
Keysight N4877A
Clock Data Recovery and Multiplexer
connected to
N4903B Serial BERT
Power Requirements
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.
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.
Use a 3.5mm/2.4mm adapter to connect
ParBERT 81250 or N4903A.
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.
If the contents are incomplete, if there is mechanical
damage, or if the instrument does not work within its
specifications, notify the nearest Keysight office. The
Keysight office will arrange for repair or replacement
without awaiting settlement.
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.
Power Cable
Allow a warm-up phase of 30 minutes prior
to performing any measurements.
Ventilation Requirements
Do not cover the ventilation holes.
USB Cable
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.
