2-1 INTRODUCTION This chapter provides information for the initial inspection and
preparation for use of the 37xxxE Vector Network Analyzer.
Information for interfacing the 37xxxE to the IEEE-488 General
Purpose Interface Bus and reshipment and storage information is also
included.
2-2 INITIAL INSPECTION Inspect the shipping container for damage. If the container or cushion
ing material is damaged, retain until the contents of the shipment
have been checked against the packing list and the instrument has
been checked for mechanical and electrical operation.
If the 37xxxE is damaged mechanically, notify your local sales
representative or Anritsu Customer Service. If either the shipping
container is damaged or the cushioning material shows signs of stress,
notify the carrier as well as Anritsu. Keep the shipping materials for
the carrier’s inspection.
WARNING
Use two or more people to lift and move this equipment, or use an
equipment cart. There is a risk of back injury, if this equipment is lifted
by one person.
2-3 PREPARATION FOR USE Except for units with Option 4 (see following page), no initial setup is
required. After unpacking, the 37xxxE is ready for use. The 37xxxE is
equipped with automatic line-power sensing, and will operate with any
of the following line voltages: 100V, 120V, 220V, 240V +5%, –10%,
48–63 Hz, 350 VA. The 37xxxE is intended for Installation Category
(Overvoltage Category) II.
-
WARNING
When supplying power to this equipment, always use a three-wire
power cable connected to a three-wire power line outlet. If power is sup
plied without grounding the equipment, there is a risk of receiving a se
vere or fatal electric shock.

PREPARATION FOR USE INSTALLATION
Option 4, Additional SD
Card for Secure
Environments
The 37xxxE is available with a second Secure Digital memory card
(SD Card) for use in secure environments. This allows the VNA to be
shipped with the System Software and Factory Cal Data on both the
standard and additional SD Cards. When the unit requires periodic
calibration, the 2nd SD Card is installed, allowing the VNA to come
out of the secure environment for calibration, while the initial SD
Card (containing proprietary customer data) remains within the se
cure environment.

INSTALLATION GPIB SETUP
2-4 GPIB SETUP All functions of the 37xxxE (except power on/off and initialization of
the SD Card) can be controlled remotely by an external computer/con
troller via the IEEE-488.2 GPIB.The information in this section per
tains to interface connections and cable requirements for the rear
panel GPIB connector. Refer to the Model 37xxxE Programming Man
ual, Anritsu Part Number 10410-00301, for information about remote
operation of the 37xxxE using the GPIB.
The 37xxxE GPIB operates with any IBM XT, AT, or PS/2 compatible
computer/controller equipped with a National Instruments
GPIB-PCII/IIA interface card and software.
Interface Connector Interface between the 37xxxE and other devices on the GPIB is via a
standard 24-wire GPIB interface cable. For proper operation, order
Anritsu part number 2100-1, -2, -4, or -5 (1, 2, 4, or 0.5 meter length)
cables through your local sales representative. This cable uses a
double-sided connector; one connector face is a plug, the other a
receptacle. These double-function connectors allow parallel connection
of two or more cables to a single instrument connector. The pin
assignments for the rear panel GPIB connector are shown in Figure
B-2, located in Appendix B.
-
-
-
Cable Length Restrictions The GPIB system can accommodate up to 15 instruments at any one
time. To achieve design performance on the bus, proper timing and
voltage level relationships must be maintained. If either the cable
length between separate instruments or the accumulated cable length
between all instruments is too long, the data and control lines cannot
be driven properly and the system may fail to perform. Cable length
restrictions are as follows:
q
No more than 15 instruments may be installed on the bus.
q
Total accumulative cable length in meters may not exceed two
times the number of bus instruments or 20 meters—whichever is
less.
NOTE
For low EMI applications, the GPIB cable should be a fully
shielded type, with well-grounded metal-shell connec
tors. (Use Anritsu 2100-series cables.)

INTERCONNECTION
There are two rear panel GPIB IEEE-488 connectors. The IEEE 488.2
connector used to interface the 37xxxE to an external computer/
controller via a standard GPIB cable. The Dedicated GPIB connector is
used to interface to plotters and a second source for multiple source
operation via a standard GPIB cable.
The 37xxxE GPIB interface can be configured to control a suitable
external plotter (refer to Chapter 6, Data Displays). In this mode of
operation, the GPIB is dedicated to this application and only the
37xxxE and the plotter are connected to the GPIB.Standard GPIB
cables are used to interconnect to the plotter.

A).
The 37xxxE model requires two IP addresses. One is internal and is
used only by the VNA for internal communication, and the other is the
IP address that can be used externally to communicate with the VNA.
The current implementation requires a continuous internal connection
and IP validity is checked as well as monitored.
The internal IP automatically updates when changes happen to the IP
address. It is highly recommended to allow the VNA to change the
internal IP automatically and retain that IP as long as it is in
operation. If it is required to assign two static IP addresses, then
changing the internal IP address is allowed, but assure that the IP is
valid, and, more importantly, available, especially if the instrument is
connected onto your LAN.
NOTE
Five classes of IP ranges are available: Class A, Class B,
Class C,Class D, and Class E. While only Classes A, B,
and C are commonly used, the VNA will accept any IP in
any range with the exception of reserved IPs. Anritsu
highly recommends IP addresses that are either Private
(Class A) or that belong to your own network. The
following Table shows a quick summary of the classes and
the IP assignments:
Class Range
A 1.0.0.1 to 126.255.255.254
B 128.1.0.1 to 191.255.255.254
C 192.0.1.1 to 223.255.254.254
D 224.0.0.0 to 239.255.255.255
E 240.0.0.0 to 254.255.255.254
2-6 37xxxE OM
INSTALLATION ETHERNET SETUP AND INTERCONNECTION
One known inconvenience is the actual assigned IP values do not
refresh automatically on the screen. A quick way to do get them
refreshed is to manually re-access the Network Utilities Menu, which
will then display them correctly.
The 37xxxE can be remotely controlled via a network server and an
Ethernet connection via the standard RJ45 connector on the rear
panel. The 37xxxE software supports the TCP/IP network protocol.
The TCP/IP protocol setup requires the following:
q IP Address: Every computer/electronic device in a TCP/IP net-
work requires an IP address. An IP address has four numbers
(each between 0 and 255) separated by periods. For example:
128.111.122.42 is a valid IP address
q Internal IP: An IP address has four numbers (each between 0
and 255) separated by periods. For example, "128.111.122.42" is a
valid IP address.
q Subnet Mask: The subnet mask distinguishes the portion of the
IP address that is the network ID from the portion that is the
station ID.The subnet mask 255.255.0.0, when applied to the IP
address given above, would identify the network ID as 128.111
and the station ID as 122.42. All stations in the same Local Area
Network (LAN) should have the same network ID but different
station IDs
q Default Gateway: A TCP/IP network can have a gateway to com-
municate beyond the LAN identified by the network ID.A gateway is a computer or electronic device that is connected to two
different networks and can move TCP/IP data from one network
to the other. A single LAN that is not connected to other LANs
requires a default gateway setting of 0.0.0.0. This (0.0.0.0) is
Lightning’s default gateway setting. If you have a gateway, then
the default gateway would be set to the appropriate value of your
gateway.
NOTE
The default gateway setting is only activated after the system power is recycled.
q Ethernet Address: An Ethernet address is a unique 48-bit value
that identifies a network interface card to the rest of the network. Every network card has a unique ethernet address permanently stored into its memory Inappropriate setting of the Default Gateway IP Address will cause the Lightning system to
appear to be locked up at start up. The instrument will appear to
stop working at the following message:
Application loaded successfully, starting system…

EXTERNAL MONITOR CONNECTOR INSTALLATION
2-7 EXTERNAL MONITOR
CONNECTOR
The rear panel External Monitor connector allows the internal display
information of the 37xxxE to be connected to an external VGA monitor
(either color or monochrome). The pinout of this 15-pin Type D
connector is shown in Figure B-5, located in Appendix B.
2-8 RACK MOUNT To install the Option 1 Rack Mount rails, refer to the below-listed pro-
cedure.
Step 1. Disconnect the line cord and any other attachments from the instru-
ment.
Step 2. Carefully place the instrument on its top (bottom-side up) on a secure
and stable work surface.
Step 3. Using a Phillips screwdriver, remove the two handles or four bumper
assemblies (and tilt bail, if installed) from the front of the unit, and
the four feet at the rear (Figure 2-1). Save the screws for later use.

This completes the installation of the slide assembly.
2-9 STORAGE OR SHIPMENT The following paragraphs describe the procedure for preparing the
37xxxE for storage or shipment.
Preparation for Storage Preparing the 37xxxE for storage consists of cleaning the unit, packing
the inside with moisture-absorbing desiccant crystals, and storing the
unit in a temperature environment that is maintained between –40
and +70 degrees centigrade (–40 to 156 degrees Fahrenheit).
Preparation for Shipment To provide maximum protection against damage in transit, the 37xxxE
should be repackaged in the original shipping container. If this
container is no longer available and the 37xxxE is being returned to
Anritsu for repair, advise Anritsu Customer Service; they will send a
new shipping container free of charge. In the event neither of these
two options is possible, instructions for packaging and shipment are
given below.
Use a Suitable Container
Obtain a corrugated cardboard carton with a 275-pound test strength.
This carton should have inside dimensions of no less than six inches
larger than the instrument dimensions to allow for cushioning.
Protect the Instrument
Surround the instrument with polyethylene sheeting to protect the finish.
Cushion the Instrument
Cushion the instrument on all sides by tightly packing dunnage or
urethane foam between the carton and the instrument. Provide at
least three inches of dunnage on all sides.
Seal the Container
Seal the carton by using either shipping tape or an industrial stapler.
Address the Container
If the instrument is being returned to Anritsu for service, mark the
Anritsu address and your return address on the carton in one or more
prominent locations.
