Inspect Shipment
Check if the Agilent N4880A shipping container
contains the following standard deliverables:
Power Requirements
Connections of the N4880A
The N4880A is controlled by the J-BERT
via USB. Using a J-BERT be certain to connect it to
a USB port on its rear side otherwise operation is not
guaranteed and install the included software package
before connecting the N4880A to your J-BERT or PC.
The N4880A is a reference clock multiplier. It provides
a multiplying phase locked loop (PLL) which enables
users to lock the pattern generators of J-BERT or
ParBERT to a lower rate reference clock. The N4880A
supports reference clock rates for PCI Express 1 to 3,
MIPI M-PHY and UHS-II standards.
There are three connectors on the front panel. All of
them are 3.5 mm SMA female. Two of them are the
input channel which can also be used single ended.
One is the output channel.
For clock multiplication, its Reference Clock Input has
to be connected to the Clock Out of the DUT. Its Clock
Output has to be connected to the Clock In of
J-BERTs PG or clock module of ParBERT.
N4903B or a
PC
The respective ports are at the front
side of the instruments.
All data and clock input and output connectors of the
BERT PG and RCM 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 power consumption is 80 VA.
The power supply automatically adapts to the
applied AC power (Auto Selection) and monitors
the AC power range.
The mains plug can 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 one 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.
Power Cable
USB Cable
If the contents are incomplete, if there is mechanical
damage, or if the instrument does not work within its
specifications, notify the nearest Agilent office. The
Agilent office will arrange for repair or replacement
without awaiting settlement.
