Before we get into the details of describing a spectrum analyzer, we might first ask ourselves: “Just what is a spectrum and why would we want to analyze it?” Our normal frame of reference is time.
We note when certain events occur. This includes electrical events.
We can use an oscilloscope to view the instantaneous value of a particular electrical event (or some other event converted to volts through an appropriate transducer) as a function of time.
In other words, we use the oscilloscope to view the waveform of a signal in the time domain.
A spectrum analyzer is a frequency-selective, peak-responding voltmeter calibrated to display the rms value of a sine wave.
The spectrum analyzer is not a power meter.
Even though it can be used to display power directly, as long as we know some value of a sine wave (for example, peak or average) and know the resistance across which we measure this value, we can calibrate our voltmeter to indicate power.
With the advent of digital technology, modern spectrum analyzers have been given many more capabilities. In this note, we describe the basic spectrum analyzer as well as additional capabilities made possible using digital technology and digital signal processing.
Phantom’s counter surveillance equipment is designed for professionals, who need to detect and locate all electronic surveillance devices.
This is done using the best tools in the market, which will help you find any bug or transmitter that could be used against you or your clients.
Phantom Technologies design and manufacture a spectrum analyzer that works passively, detecting all kinds of wireless communication bugs that work actively.
Those devices can detect even radio waves or cellular transmission signals that are not visible or audible to the naked eye.
This allows users to survey their surroundings for any unauthorized communications.
Our product provides full RF signal scanning, for the analysis and detection of the RF spectrum.
It is designed to detect illegitimate eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum.
It leverages powerful signal processing algorithms to achieve superior sensitivity in locating interfering signals in today’s crowded wireless environment.
*Phantoms has developed and manufactured a wide range of comprehensive, modular, and scalable active and passive solutions for different markets.
