Power Requirements
Connections of the N4903B
For all differential outputs of the PG: if only the
normal or complement output is used in your test
setup, the unused output must be terminated
with 50 Ohm. The same is true for the
differential inputs of the ED.
The ED CLK IN connector must be terminated with
50 Ohm when not used.
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 450 VA with all options
installed. 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 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.

When the front panel switch is off, the instrument
is in standby mode. The instrument can only be
disconnected from the AC line power by
disconnecting the power cord. The instrument
must be positioned so that the operator can easily
access the power cable inlet.
Allow a warm-up phase of 30 minutes prior
to performing any measurements.
