A signal analyzer is an essential tool for engineers and technicians in the field of electronics. It allows for the measurement and analysis of electrical signals to determine their magnitude, phase, and other important characteristics. One of the most trusted and renowned brands in signal analyzers is Hewlett Packard (HP). HP has a long history of producing high-quality and reliable instruments, and their dynamic signal analyzers are no exception.
What is a Dynamic Signal Analyzer?
A dynamic signal analyzer, also known as a spectrum analyzer or signal analyzer, is a device used to measure the magnitude and phase of an input signal at a single frequency within the instrument's bandwidth. It employs digital techniques to extract useful information carried by an electrical signal. Signal analyzers can perform various operations, including spectrum analysis, phase noise analysis, power analysis, distortion analysis, and modulation quality analysis.
The HP dynamic signal analyzers are designed to provide accurate and precise measurements, with a wide frequency range and high dynamic range. They combine the superior performance of a swept tuned spectrum analyzer with vector signal analyzer (VSA) capabilities, allowing for in-channel measurements such as error vector magnitude (EVM) that require both magnitude and phase information.

Frequently Asked Questions
What is the difference between a spectrum analyzer and a signal analyzer?
A spectrum analyzer measures the magnitude of an input signal versus its frequency over the full frequency range of the instrument to determine the power of signals. On the other hand, a signal analyzer measures both the magnitude and phase of an input signal at a single frequency. While spectrum analyzers are used to characterize the performance of a device and its contribution to overall system performance, signal analyzers provide more detailed information about the signal, such as modulation quality and phase noise.
What is the difference between an oscilloscope and a spectrum analyzer/signal analyzer?
An oscilloscope allows you to view the instantaneous value of a particular electrical event as a function of time. It displays the waveform of a signal in the time domain. On the other hand, spectrum analyzers and signal analyzers perform measurements in the frequency domain to measure energy at each particular frequency. While an oscilloscope provides information about the time-domain characteristics of a signal, spectrum analyzers and signal analyzers provide information about the frequency-domain characteristics.
How does a spectrum analyzer work?
A spectrum analyzer works by transforming a time-domain signal into its frequency-domain equivalent. It uncovers sources of interference by displaying the spectral components independently. The frequency domain allows you to determine the harmonic content of a signal, such as out-of-band emissions and distortion. A spectrum analyzer can operate in real-time or swept-tuned mode, depending on the specific type of analyzer.

A real-time spectrum analyzer gathers data in the time domain and then translates it into the frequency domain using the Fast Fourier Transform (FFT). It captures transient and fast signals quickly, providing a real-time display of the energy at all frequency components.
What are the main types of spectrum analyzers?
There are two main types of spectrum analyzers: swept-tuned analyzers and real-time analyzers. Swept-tuned analyzers use a single narrow filter that is tuned across a range of frequencies to produce a spectrum display. Real-time analyzers use digital signal processing to provide additional measurement capability and display the energy at all frequency components simultaneously.
