Warning To avoid hazardous electrical shock, do not turn on the 4396B
when there are signs of shipping damage to any portion of the
outer enclosure (for example, covers, panel, or display)
Inspect the shipping container for damage. If the shipping container
or cushioning material is damaged, it should be kept until the contents
of the shipment have been checked for completeness and the 4396B
has been checked mechanically and electrically. The contents of
the shipment should be as listed in Table 1-1. If the contents are
incomplete, if there is mechanical damage or defect, or if the analyzer
does not pass the power-on selftests, notify the nearest Agilent
Technologies oce. If the shipping container is damaged, or the
cushioning material shows signs of unusual stress, notify the carrier as
well as the Agilent Technologies oce. Keep the shipping materials
for the carrier's inspection.

Installation and Setup Guide 1-5
Operation Environment
The 4396B must be operated under within the following environment
conditions, and sucient space must be kept behind the 4396B to
avoid obstructing the air ow of the cooling fans.
Temperature: 0 C to 40 C
Humidity: less than 95% RH at 40 C
Note The 4396B must be protected from temperature extremes which could
cause condensation within the instrument.
Providing clearance to dissipate heat at installation site
To ensure the speci cations and measurement accuracy of the
product, you must keep ambient temperature around the product
within the speci ed range by providing appropriate cooling clearance
around the product or, for the rackmount type, by forcefully
air-cooling inside the rack housing. For information on ambient
temperature to satisfy the speci cations and measurement accuracy of
the product, refer to \Speci cations" in Chapter 10 of the Function
Reference.
When the ambient temperature around the product is kept within the
temperature range of the operating environment speci cation (refer
to \Operation Conditions" in Chapter 10 of the function reference),
the product conforms to the requirements of the safety standard.
Furthermore, under that temperature environment, it has been
con rmed that the product still conforms to the requirements of the
safety standard when it is enclosed with cooling clearance as follows:
Conditions
Rear 180 mm
Side 60 mm
Instruction for Cleaning
To prevent electrical shock, disconnect the 4396B power cable from
the receptacle before cleaning. Wipe with a dry cloth or a soft cloth
that is soaked with water and wrung tightly without undeue pressure
to clean the casing. Do not attempt to clean the 4396B internally.

Installation and Setup Guide 1-11
Connecting a Test Set for Network Analyzer Mode
To use the network analyzer mode of the analyzer, a test set is
required to measure the transmission and re ection characteristics of
the device under test (DUT).
You can use either the 87512A/B transmission/re ection (T/R) test
set or the 85046A/B S-parameter test set. The 87512A/B T/R test set
measures re ection and transmission in the forward direction only.
The 85046A/B S-parameter test set measures both the forward and
reverse directions without reconnection.
For more information about the test sets, see chapter 9 of the
Function Reference manual.
Connecting a Transmission/Re ection Test Set

1. Place the transmission/re ection (T/R) test set in front of the
analyzer.
2. Connect the R and A ports of the analyzer and the T/R test set to
each other.
3. Connect the RF OUT port of the analyzer and the RF IN port of the
T/R test set with a semi-rigid cable.
