Installing the BNC Model 7500 Real Time
Spectrum Analyzer
Ensure that you read and understand the following information about safety and
electrostatic discharge before you unpack and install the Model 7500.
Warning: Only trained and qualified personnel should be allowed to install or replace
this equipment. Read the installation instructions before you connect the system to its
power source.
Preventing Electrostatic Discharge Damage
Electrostatic Discharge (ESD) is a single-event, rapid transfer of electrostatic charge
between two objects, such as an operator and a piece of electrical equipment. ESD can
occur when a high electrostatic field develops between two objects in close proximity.
ESD occurs when electronic components are improperly handled and is one of the major
causes of device failures in the semiconductor industry.
Electrostatic discharge is more likely to occur with the combination of synthetic fibers and
dry atmosphere. Always follow these steps to prevent ESD.
Warning: Never open the front or rear panels of the Model 7500 as personal injury may
result and opening the chassis will void the warranty. There are no user-serviceable
parts inside. Always contact Berkeley Nucleonics Corp support for service.
Caution: To prevent ESD, wear an ESD-preventive wrist strap that you provide,
ensuring that it makes good skin contact.
Caution: Do not touch any exposed contact pins or connector shells of interface ports
that do not have a cable attached. If cables are connected at one end only, do not touch
the exposed pins at the unconnected end of the cable.

Connecting to the Model 7500
The Model 7500 is a network device and typically all communications with the Model
7500 are via a Gigabit Ethernet connection, either directly to a computer or across an IP
network. The Model 7500's Gigabit Ethernet connection provides control and status of
the Model 7500 using SCPI commands and data using the VRT protocol.
This section provides instruction for different methods of connecting to the Model 7500
via its Ethernet port and obtaining its IP address.
Deciding on Your Network Topology and IP Address Allocation
Note: To connect with the Model 7500 via its Ethernet port, you must decide on both the
topology of your network connection and how your Model 7500 obtains its IP address.
As illustrated in the following picture, the Model 7500 supports any IP network topology
connected via its Ethernet port including:
a direct connection to a computer across an RJ-45 Ethernet cable as per the
Connecting the Model 7500 Directly to a Computer section;
a connection across a routed local network, whether on the same subnet or
across different subnets or across a routed wide-area network such as the
Internet, as per the Connecting to the Model 7500 Across a Network section.
The Model 7500 also supports different methods of obtaining its IP address including:
dynamic IP address allocation via the Dynamic Host Configuration Protocol
(DHCP), which is applicable to a routed network topology that has a DHCP
server;
dynamic IP address allocation via the Automatic Private IP Addressing (APIPA)
protocol (otherwise known as Auto-IP) which is applicable for where a DHCP
server is not available. This method allows a direct connection to a computer
that supports Auto-IP or to a local network using a switch. With Auto-IP, a host
network device randomly assigns itself a link-local address in the 169.254.x.y

subnet when it fails to contact a DHCP server. Many operating systems (OSs),
including Windows, support Auto-IP;
static IP address allocation, which is applicable to any network topology.
Changing the Model 7500's Method of IP Address Allocation
This section provides the instruction for reconfiguring one IP address allocation type to
another.
Note: The Model 7500 is configured for dynamic IP address allocation by factory default.
If your Model 7500 is configured for dynamic IP allocation, then it may be reconfigured for
static IP address allocation using either its web administration or USB console. Using the
administration console in this scenario requires first a connection to the Model 7500 via
its Ethernet port, which in turn requires dynamic allocation of its IP either by DHCP or
Auto-IP.
If your Model 7500 is configured for static IP allocation, then it may be reconfigured for
dynamic IP address allocation using its administration or USB console or via a hardware
reset. Using the hardware reset to reconfigure to dynamic IP allocation is the simplest
method and is described in the Reset to Factory Settings section. Using the
administration console requires a connection to the Model 7500 via its Ethernet port.
Connection to the Model 7500 using dynamic or static IP allocation is described in the
following sections. The console usage is described in the Administration Console or
Using the USB Console section.
Connecting the Model 7500 Directly to a Computer
This section provides instruction on connecting the Model 7500 directly to a computer via
their Ethernet ports using an Ethernet cable.
In order to connect directly to a Model 7500, the host PC might require a spare Ethernet
interface that is not otherwise used as its primary network connection. For example, you
may use a wireless connection for primary network connectivity or obtain a second
Ethernet card or USB adapter to connect to the Model 7500.
To connect the Model 7500 directly to your computer:
1. Decide on whether you will be using static or dynamic IP allocation. Regardless
of which method you choose, both your PC's and the Model 7500's Ethernet
interface must be configured for the same method of IP allocation. If necessary,
configure your Model 7500 to your chosen method of IP allocation following the
instruction in the Changing the Model 7500's Method of IP Address Allocation
section.
Note: Auto-IP support is only provided in Model 7500 with firmware v4.0 or higher.
Update your unit with the correct firmware before using the Auto-IP capability.
2. Connect the provided Ethernet cable to both your PC's and the Model 7500's
Ethernet ports.

3. Power up the Model 7500 and wait a minute for it to complete booting.
4. Check to ensure that either your PC's or the Model 7500's LINK indicator is
illuminated. If it is not then your PC may not support automatic crossover on its
Ethernet connection and you may require an RJ-45 crossover Ethernet cable as
specified in the section.
5. If you're using static IP allocation then skip to the next step. Otherwise, check
the STS LED for the Auto-IP setup completion (take a minute or longer).
Note: While the Model 7500 is searching for a DHCP server, the STS LED blinks yellow
slowly until it obtains an IP address either via DHCP or Auto-IP. The STS LED blinks in a
green heartbeat pattern if it has set up successfully to using an Auto-IP address.
Then verify the host PC's IP configuration using the Python API Discovery Tool
or with a Windows OS, open a Command window and type ipconfig to show
the IP addresses assigned to each interface. The Ethernet interface should
show a 169.254.xxx.yyy address as seen in the following picture as an example.
6. Use the Python API Discovery tool or the RTSA GUI (as shown in the following
figure), both provided by Berkeley Nucleonics Corp, to determine the Model
7500's assigned IP address. In order for the Discovery tool to locate the Model
7500, both your computer and the Model 7500 must be configured for the same
subnet. If you are using Auto-IP dynamic IP allocation, then they will both be on
the same 169.254.x.y subnet. If you are using static IP and the Discovery tool
cannot locate the Model 7500, then you need to have prior knowledge of its static
IP address or use the USB console.

7. The assigned IP address may now be used to communicate with the Model
7500.
Note: Link-local addresses used for Auto-IP are non-routable, so communications is
limited to devices within the local subnet. This restriction may be an issue when running
virtual machines (e.g. Mac Parallels, VirtualBox, etc.) that may be connected through
virtual routers to the host PC's physical network interface.
Note: After obtaining a link-local address, the Model 7500 continues to request a DHCP
address. If a DHCP server responds at a later time, the link-local address is overwritten
with the offered IP address. This new address is retained until the network cable is
physically unplugged or the Model 7500 is restarted.
Connecting to the Model 7500 Across a Network
This section provides instruction on connecting the Model 7500 to a computer across a
routed local network whether on the same subnet or across different subnets or across a
routed wide-area network such as the Internet.
To connect the Model 7500 across a network:
1. Decide on whether you will be using static or dynamic IP allocation. Both your
PC and the Model 7500 do not need to be configured for the same method of IP
allocation; although to locate your Model 7500 using Berkeley Nucleonics Corp's
Discovery tool requires that they be on the same subnet. If necessary, configure
your Model 7500 to your chosen method of IP allocation following the instruction
in the Changing the Model 7500's Method of IP Address Allocation section. If you
are using dynamic IP allocation then your router or your network must support a
DHCP server.
2. Connect the provided Ethernet cable to both your router's and the Model 7500's
Ethernet ports.
3. Power up the Model 7500 and wait a minute for it to complete booting. The
sequence of connecting and powering on are inconsequential.
4. Check to ensure that either your router's or the Model 7500's LINK indicator is
illuminated.
5. If your Model 7500 is behind a firewall or a router with firewall capability then
your network's DHCP server is likely assigning private IP addresses (e.g.
192.168.xxx.xxx, 10.xxx.xxx.xxx, 172.xxx.xxx.xxx) and the firewall is likely
providing some form of network address translation (NAT) function. If this is the
case and if you require access to the Model 7500 from outside your firewall, then
you will likely have to configure the firewall to allow port forwarding on port 37000
and 37001. If necessary, consult with your network administrator.
6. Use the Python API Discovery tool or the RTSA GUI (as shown in the following
figure), both provided by Berkeley Nucleonics Corp, to determine the Model
7500's assigned IP address. In order for the Discovery tool to locate the Model
7500, both your computer and the Model 7500 must be configured for the same
subnet. If you are using DHCP then you may have to query your router's
allocation tables to determine the IP that is allocated to your Model 7500's MAC
address. If you are using static IP and the Discovery tool cannot locate the

Model 7500, then you need to have prior knowledge of its static IP address or
use the USB console. If necessary, consult with your network administrator.
7. The assigned IP address may now be used to communicate with the Model
7500.

Administration Console
This section provides instruction on connecting to the Model 7500 via its web-based
administration console. The administration console provides the ability to:
obtain status information from the Model 7500;
change date and time configuration;
change IP configuration;
upgrade the Model 7500's software/firmware;
upload customized calibrations settings;
and/or reset the Model 7500.
All of these functions may be performed via the network either locally or remotely.
Connecting via Your Web Browser
Connect to the Model 7500's administration console by entering the IP address of your
Model 7500 into a web browser's web address dialog. The following "Status" web page
should appear providing information on the Model 7500's MAC address, hardware and
software versions.
Note that if you have earlier versions with firmware image v3.2.6 or earlier, the “Product
version” field would be labeled as “Hardware version”. This field is important for selecting
the correct firmware image to update, i.e. older product version can only be updated with
firmware v3.2.7 or lower; and current production version with firmware v4.0.0 or higher.

Configuring the Model 7500's Time
The Model 7500 provides for setting its time either manually or as per the PC's time or via
an NTP server.
Note: The Model 7500 stores its time based on the UTC Coordinated Universal Time
zone and otherwise has no notion of local time-zones. Conversely, the web dialog
translates and displays the Model 7500's time based on the local time-zone setting of the
PC.
1. Click on the "Time Configuration" link in the left column menu of the
administrative console web page. The following "Model 7500 Device Time
Configuration" web page should appear.
2. Select the time synchronization source.
3. If “Enter time manually” is selected then enter the date and time based on your
local time-zone.
4. If “Use current PC time” is selected then the data and time fields will be
populated automatically.
5. If “NTP” is selected, enter at least one NTP server IP address and select whether
the time be synced just this one time or continuously. If “continuously” is
selected, the Model 7500's time is synchronized to the NTP server on a

continuous and regular basis, the regularity of which is optimally determined
automatically.
6. Click the “Apply” button.
Configuring the Model 7500's IP Address
The Model 7500 provides options for selecting whether the Model 7500's IP address is
obtained dynamically using DHCP or is set manually to a static address.
Caution: Please note that if the Model 7500's IP address is set to static IP then the only
way to communicate with the Model 7500 is via that IP address. If you mistakenly enter
the wrong IP address and/or subnet mask, or forget the IP address, then you can change
the IP configuration Using the USB Console or perform a Reset to Factory Settings.
1. Click on the "IP Configuration" link in the left column menu of the administrative
console. The following "Model 7500 Device IP Configuration" web page should
appear. Once the “Apply” is clicked, the new configuration will take effect
immediately and the current configuration and web page will no longer be valid.
Updating the Model 7500's Firmware
This section will step you through updating the Model 7500's firmware. The firmware
install file contains firmware images associated with the Model 7500's FPGA, Linux
operating system and the embedded application. The process of updating will copy the
new images to the Model 7500 in addition to and without erasing the current installed
images. The new install will only take effect upon the Model 7500 being restarted.

Note: Updating firmware might over-write any user-defined calibrated values, see
Customizing the Model 7500's Calibration for more information.
1. Click on the "Firmware Install" link in the left column menu of the administrative
