Visionic Spectrum Analyzer: IP connections and routing

Visionic Spectrum Analyzer is a client-server program. In many cases, the client can be physically far away from the server; and in such cases there are security measures such as firewalls, routers and so on, that need to be taken into account.

The goal of this text is to explain and specify which IP ports are used. This text can be used by system engineers and network administrators to allow specific ports between Visionic SA client and the server.

The Visionic Spectrum Analyzer streams the data from the instrument to all of its clients. Like most of the streaming protocols, the Visionic Spectrum Analyzer uses UDP to disseminate the trace (information from the instrument) to all its clients.

At the same time, the Spectrum Analyzer Server has one TCP/IP port opened to accept command and control instructions coming from different clients.

Please refer to the picture below where you can see the initial handshaking negotiations between Visionic Spectrum Analyzer Server and Client:


As we can see from the image above, following IP ports are used:


Visionic Spectrum Analyzer 2.0

The Visionic Spectrum Analyzer 2.0 (VSA) is an Add-On and Standalone software solution which will enable the user, through an intuitive GUI, to perform advanced analysis and signal measurements.

VSA allows remote monitoring of your physical devices; it can monitor different VSA devices from various PCs, anywhere on the network.


With VSA, you will have the ability to monitor and control your physical devices remotely and without any interruption. You will also be able to monitor different devices from various PCs anywhere on the network.

The software has all the features of the physical, hardware SA device included but is improved with a broad range of smart add-ons.

One of the most valuable features of VSA is logging and log playing-out. SA logs all the information coming from the instrument (signal trace, commands issued, alarms, alarm box).The process of logging is automated and logs are stored for 30 days. This feature allows operator to play back the behavior of the instrument in the past and inspect closely the problems that occurred.

All the information coming from the instrument is logged and then the data is exported to an .avi file, so that the user can graphically see what was happening during a specified period of time, anytime he desires.

VSA includes a configurable surveillance zone (Alarm Box), in which the signal is expected to be found. If not, an alarm is raised. This feature is designed to control the quality of the monitored signal. It defines limits (min/max frequency and min/max power) where the signal is expected to be present. In case the signal power deteriorates, an alarm is generated and sent to registered alarm listeners.

Moreover, the Visionic Spectrum Analyzer has an extended compatibility. The software solution will function with any manufacturer, such as Agilent, Rohde & Schwartz and many others. Our Spectrum Analyzer is easily extendable to any device with a connection interface to PC. The way users can connect the Spectrum Analyzer to a device is limited by the specific device’s communication capabilities (interfaces) only.

You will have uninterrupted remote monitoring of your physical devices, as well as remote real-time interaction with any spectrum analyzer devices.

The signal graph will appear on your monitor just like on your physical device. Moreover, it presents command buttons from the instrument, allowing you to control the physical SA remotely. Regardless of the manufacturer, the command board is presented in a same way. Sometimes, it needs time simply to learn how to use a new instrument. In Spectrum Analyzer, all the parameter settings, each command button is at the same place regardless of the instruments connected. And it remains the same for any additional instrument. Furthermore, the operator can fully customize the front panel of the application and tailor it according to his/her preferences.

Furthermore, the VSA unifies graphical user interface of various equipment, thus making the switching of the equipment transparent to the operator.

VSA includes SNMP agent, which issues SNMP traps in case of alarms/anomalies. This allows any SNMP Manager system to receive SNMP notifications about state of Spectrum Analyzer instruments.

The Connection setup is done in SAserver GUI. To configure connection details, simply select desired tab (LAN, VISA or SERIAL), and then fill the available fields with the correct data.

The Visionic Spectrum Analyzer can create presets for the physical device. Our application is able to save them in a local file or on the server, which allows not only loading presets later, but sharing them easily with other clients as well.

Lastly, VSA can be integrated with the higher level M&C – Visionic system, as a typical element or device, without any difficulty. Just like with any other device, Visionic is capable of presenting and logging Spectrum Analyzer’s alarms, statuses and other parameters.

The Spectrum Analyzer option can be used as an independent program, or as a device included in the Visionic schematic. The Spectrum Analyzer subsystem allows complete control over the device, along with options for logging different data points (such as centre frequency and centre amplitude). The analyzers can be connected via LAN and serial port (Agilent) or via USB ports (R&S).
