Signal Analyzer

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.

Our Solution

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.

Our Solution

  1. Frequency range: Signal analyzers can typically measure signals over a wide frequency range, from a few kilohertz up to several gigahertz. This makes them useful for analyzing a wide range of signals, including those used in wireless communication systems.
  2. Accuracy: Signal analyzers are designed to provide accurate measurements of signal properties such as frequency, amplitude, and phase. This allows engineers and technicians to troubleshoot and optimize RF systems.
  3. Advanced features: Signal analyzers may include advanced features such as signal demodulation, modulation analysis, and spectrum analysis. These features can help identify and diagnose problems in RF systems.
  4. Wide range of applications: Signal analyzers are used in a wide range of applications, including telecommunications, aerospace, defense, and research and development.
  5. User-friendly interfaces: Many modern signal analyzers come with user-friendly interfaces, making them easy to use for both novice and experienced users.
  6. Flexibility: Signal analyzers can be configured for various types of measurements and can be used in different types of test setups.
