.Component replacement and
internal adjustments must be made only by qualied maintenance personnel. Do not replace
components with the power cable connected. Under certain conditions
, dangerous voltages
may exist even with the power cable removed. T
oavoid injury
,always disconnect power and
discharge circuits before touching them.
Do NOT Service or A
djust While Alone

protect against damage to the instrument.
Indicates dangerous voltage (terminals fed from the interior by voltage
exceeding 1000 volts must be so marked).
Protective ground terminal. F
or protection against electrical shock in case of
afault in the instrument. Used with wiring terminals to indicate the terminal
that must be connected to ground before operating equipment.
Low-noise or noiseless
,clean ground (earth) terminal. Used for a signal
common, as well as providing protection against electrical shock in case
of afault in the instrument. A terminal marked with this symbol must be
connected to ground in the manner described in the installation (Operation)
manual, and before operating the equipment.

Preparation for Use
Introduction
This chapter describes how to prepare the 41900A PI-Network T
est Fixture for use
.The topics
include the following:
Initial inspection.
Repackaging the 41900A for shipment.
Initial Inspection
The 41900A has been carefully inspected electrically and mechanically before being shipped
from the factory
.It should be in perfect physical condition, no scratches
,dents or the like
, and
it should be in perfect electrical condition. V
erify this by carefully performing an incoming
inspection to check the xture for signs of physical damage and missing contents
.If any
discrepancy is found, notify the carrier and Agilent T
echnologies .Y
our Agilent T
echnologies
sales oce will arrange for repair and replacement without waiting for the claim to be settled.
1. Inspect the shipping container for damage
.Keep the shipping materials until the incoming
inspection is completed.
2. V
erify that the shipping container contains everything shown in Figure 2-1 and listed in
T
able 2-1.If the 41900A is ordered with Option 001 (Load Capacitor A
dapter Kit), it should
also contain the parts listed in Table 2-2 .
3. Inspect the exterior of the 41900A for any signs of damage
.

2-4 Preparation for Use

Repackaging the 41900A for Shipment
If shipment to aAgilent T
echnologies service center is required, the 41900A should be
repackaged using the original factory packaging materials.
If this material is not available
, comparable packaging materials may be used. Wrap the 41900A
in heavy paper and pack in anti-static plastic packing material. Use sucient shock absorbing
material on all sides of the 41900A to provide a thick, rm cushion and to prevent movement.
Seal the shipping container securely and mark it
FRAGILE
