Step 2. Set Up the PNA
Step 2. Set Up the PNA
1. Using the PNA Installation and Quick Start Guide, set up the network analyzer.
2. If you are installing your PNA in an equipment rack, be sure to leave at least 2 rack
units of space below the analyzer to install the test set.
NOTE For the N4420B or N4421A/B test set, connect the PNA to the test set
before placing in the rack as a single unit on one set of rails. Refer to“Step
3. Attach the PNA to the Test Set” on page 1-7 for instructions.

Step 3. Attach the PNA to the Test Set
Step 3. Attach the PNA to the Test Set
(N4420B or N4421B Test Set Only)
If your test set is an N4419B, continue with “Step 4. Install the System on a Bench Top
or in an Equipment Rack” on page 1-11.
The PNA is attached to the N4420B and N4421B test sets using lock links at the front
and locking feet at the rear.
Preparing the PNA
1. Remove the four feet from the bottom of the PNA.
2. Remove the screws from the two lower rear panel standoffs.
3. Install the two rear locking feet (5023-0132) where the standoffs were removed. The
locking feet may require GENTLE tapping with a hammer to seat properly. Use the
screws (part number 0515-1619) that are included to secure the feet to the PNA.

Step 4. Install the System on a Bench Top or in an Equipment Rack
Step 4. Install the System on a Bench Top or in an
Equipment Rack
The test system can be installed on a bench top or in an equipment rack.
In all installations, consider the following ventilation requirements when deciding
where to set up your test system.
CAUTION Ventilation Requirements:
When installing the product in a cabinet, the convection into and out of the
product must not be restricted. The ambient temperature (outside the
cabinet) must be less than the maximum operating temperature of the
instrument by 4 °C for every 100 watts dissipated in the cabinet. If the total
power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.
Refer to the section that applies to your installation.
•For bench top installation, continue on page 12.
•For equipment rack installation, continue on page 13.

1-12
Installing the Test Set
Step 4. Install the System on a Bench Top or in an Equipment Rack
To Install on a Bench Top
1. Place the test set and PNA on a bench top. In the example illustration shown below,
the system is placed on a riser as an alternative to the bench top. Make sure that
there is at least four inches of clearance on the sides and back of the system for
adequate ventilation.
The front panel test cables are shown only as a reminder to make sure they can easily
reach the test surface of the bench.
CAUTION Consider the ventilation requirement described on page 11 when selecting
the location of your system.
2. Continue with “Step 5. Make the Interconnections between the Test Set and the PNA”
on page 1-17.

1-13
Installing the Test Set
Step 4. Install the System on a Bench Top or in an Equipment Rack
To Install in an Equipment Rack
You may install the system in an equipment rack in one of following two ways:
When you install the test set in an equipment rack, you will install rails in the rack to
support the weight of the test set, attach the handles and the rack mount flanges to the
test set, and secure the test set to the equipment rack.
1. Ensure that the front handle kit, the rack mount flange kit, and the rack mount rail
set are complete.
NOTE If any items are damaged or missing from a kit, contact us to order a
replacement kit. Items within these kits are not individually available.
2. Install the rails into the equipment rack using the instructions provided. Consider
that the test set is two rack units high (3.5 inches). Mount the test set immediately
below the PNA.
NOTE For the N4420B or N4421B test set, connect the network analyzer to the
test set before placing in the rack as a single unit on one set of rails.
3. Attach the cabinet mount flanges and the handles to the sides of the front panel,
Removing Feet from PNA Leaving Feet attached to PNA
1. Install one set of rails into the
equipment rack
2. Remove feet from Test Set and PNA
3. Attach mount flanges and the handles to
