When it comes to spectrum analysis, Hewlett Packard (HP) is a trusted name in the industry. Their spectrum analyzers are known for their accuracy, reliability, and advanced capabilities. In this article, we will explore the features and benefits of HP spectrum analyzers, as well as discuss the difference between spectrum analyzers and Vector Signal Analyzers (VSA).
What does a spectrum analyzer do?
A spectrum analyzer is a powerful tool used for analyzing and measuring the frequency spectrum of an electrical signal. It provides a visual representation of the signal's frequency content, allowing engineers and technicians to identify and troubleshoot issues in various applications such as telecommunications, electronics, and RF testing.
HP spectrum analyzers are equipped with advanced features that make them suitable for a wide range of applications. They offer high-frequency accuracy, wide dynamic range, and excellent resolution, allowing users to accurately measure and analyze signals across different frequency ranges.
What is the best budget spectrum analyzer?
When looking for a budget-friendly spectrum analyzer, HP offers several options that provide excellent performance at an affordable price. The HP 8560E series is a popular choice for those on a budget. It offers a frequency range of up to 25 GHz and provides high-resolution measurements with a wide dynamic range.

How accurate is a spectrum analyzer?
HP spectrum analyzers are known for their high accuracy and reliability. They are designed to provide precise measurements, ensuring that users can trust the results obtained. The accuracy of a spectrum analyzer is determined by several factors, including frequency accuracy, amplitude accuracy, and resolution bandwidth.
HP spectrum analyzers are calibrated to ensure accurate frequency measurements. They employ advanced calibration techniques and high-quality components to achieve excellent frequency accuracy. Additionally, they feature high-resolution displays and precise amplitude measurements, allowing users to accurately analyze signal levels.
What is the difference between a spectrum analyzer and VSA?
A spectrum analyzer and a Vector Signal Analyzer (VSA) are both powerful tools for analyzing and measuring signals. However, there are some key differences between the two.

It provides a visual representation of the signal's frequency content, allowing users to identify and analyze different frequency components. Spectrum analyzers are useful for general-purpose spectrum analysis and troubleshooting.
On the other hand, a VSA measures dynamic signals and produces complex data results. It is capable of measuring time-varying and complex modulated signals. VSA's offer several advantages over swept-tuned analysis, including the ability to measure dynamic signals accurately and the ability to process all frequencies simultaneously.
VSA's use a parallel bank of filters and capture the entire signal event, allowing for real-time analysis without missing any part of the input signal. This makes them ideal for applications that involve fast-changing signals, such as digital communications.
VSA Measurement Advantages
The VSA offers some distinct advantages over swept-tuned analysis. One of the major advantages of the VSA is its ability to better measure dynamic signals. Dynamic signals generally fall into one of two categories: time-varying or complex modulated.
Swept-spectrum analyzers sweep a narrowband filter across a range of frequencies, sequentially measuring one frequency at a time. This technique works well for stable or repetitive signals but gives misleading results for signals that change during the sweep. Additionally, swept-spectrum analyzers only provide scalar (magnitude only) information.

This allows for accurate measurement of dynamic signals and provides complex data results. The VSA's ability to track fast-changing signals in real-time makes it a valuable tool for signal analysis and troubleshooting.
The VSA decreases measurement time
Parallel processing in VSA's also yields faster measurement time for high-resolution measurements. Swept-tuned analyzers sweep frequencies slowly enough to allow analog resolution bandwidth filters to settle. In contrast, VSA's measure across the entire frequency span at one time, significantly reducing measurement time.
For narrow-bandwidth measurements, the VSA can complete a measurement up to 1000 times faster than conventional swept-spectrum analyzers. This is because the VSA's sweep speed is limited by data collection and digital processing time, which is usually negligible compared to the settling time of analog filters.
In addition to faster measurement time, the VSA offers higher frequency resolution. Swept-spectrum analyzers are limited by the physical bandwidth of the sweeping filter, while VSA's do not have this limitation. Some VSA's can resolve signals spaced less than 100 µHz apart, allowing for precise frequency analysis.

Another useful feature of VSA's is the time-capture capability. This allows users to record actual signals in their entirety without gaps and replay them later for analysis. The full set of measurement features can be applied to the captured signal, enabling detailed analysis and troubleshooting.
VSA's also provide multi-domain measurements in one instrument, thanks to the use of digital signal processing (DSP). DSP provides time, frequency, modulation, and code domain measurement analysis in a single instrument. It allows for easy and accurate views of both time and frequency domain data, as well as vector-modulation analysis.
The use of DSP in VSA's improves the quality of measurements and increases the analyzer's value to users. It enables a wide range of measurements on various digital communication standards and produces useful measurement displays and signal quality data.
While VSA's offer significant advantages, it's worth noting that conventional analog swept-tuned analyzers provide higher frequency coverage and increased dynamic range capability.
