A key attribute that sets Holzworth HA7000 Series Real Time Phase Noise Analyzers apart from the competition is the capability for measuring the absolute phase noise floor of each instrument. This is very valuable information because like spectrum analyzers, no two phase noise analyzers are identical even if they are of the same make and model number. The absolute noise floor measurement capability is available with Holzworth phase noise analyzers due to a unique reconfigurable front end that allows users to access several internal modules. The ability to measure the actual noise floor of the instrument provides users with a known level of confidence in their data by demonstrating the instrument’s true noise floor relative to the measured data.

A Microwave Journal online brief in March 2016 gives credence to Holzworth's HSX Series, Multi-Channel RF Synthesizer product line. Holzworth is the market leader in providing the highest independently tunable channel density in rack mountable units. The HSX Series does this with industry leading performance. This can be viewed directly on the Microwave Journal website.

Microwave Journal Online recently interviewed Holzworth's original founder and President / CTO. In this interview, Jason discusses how the company was started, some highlights regarding Holzworth's unique technologies, and where the company is headed.

As communications systems are transferring more data at higher speeds within limited bandwidths, the adverse effects of intermodulation are becoming less tolerable. Precise multi-tone signal generation is extremely valuable for emulating the non-linear artifacts of a device or system for IMD (intermodulation distortion) performance testing. IMD testing is performed by subjecting a DUT to two or more tones for simulating the effects of real-world operating conditions in a controlled environment

Holzworth’s ultra low phase noise synthesizers are unique in that they do not utilize PLL based architectures to achieve broadband, low phase noise frequency generation... multi-channel synthesizers benefit greatly from the elimination of phase locked loops...

Presented at IMS/MTT-S 2008 in Atlanta by Holzworth's CTO. This presentation contains valuable material that covers phase noise basics, including how to measure the absolute phase noise of an oscillator using a nontraditional, yet basic phase noise test circuit architecture.

Many electronic devices are subject to short-term, random fluctuations in phase, referred to as phase noise. This phenomenon impacts signal quality in communications systems by increasing symbol errors or reduces sensitivity in radar systems by masking low power return signals. Engineers can use phase noise analyzers to measure the phase noise performance of an entire system or individual components. In this application note, learn how high-performance phase noise analyzers are particularly effective in quantifying the magnitude of phase noise with absolute and additive measurements.

Phase noise is present in all electronic signals. Phase noise is caused by the unintentional phase modulation of an RF waveform, no RF signals are perfect. The phase noise component will then reduce the fidelity of an RF signal which can have significant effects, causing higher symbol errors in communications systems or masking returns in radar systems. To describe phase noise another way, the same phenomena in the time domain is called jitter. Like phase noise, it will affect the signal’s overall fidelity. One of the main ways to optimize system performance is by reducing phase noise as much as possible. Due to phase noise’s potential significant negative impacts, it is essential to be able to optimally measure phase noise throughout the testing process.

Phase Noise Analysis has traditionally been a smaller sector of the electronics test and measurement market, primarily being a parameter that was verified by defense RADAR systems providers. With the rapid growth of high-speed communications markets, everyone from chipset manufacturers to complete systems providers have been adopting phase noise as a key parameter for quantifying RF signal stability performance. Furthermore, phase noise can be quickly converted to jitter, enabling a reliable method for rapid jitter analysis in time domain applications.

UPDATED White Paper for the HA7000C Series Real Time Phase Noise Analysers. Oscillator manufacturers and engineers who frequently need to evaluate the performance of ultra low phase noise oscillators. They need to perform these tests both quickly and accurately...

There are many paths to accomplishing a broadband RF synthesis architecture. Depending on the application, there are trade offs to be considered. This white paper compares the advantages and disadvantages among three common architectures: DDS/Direct Analog, PLL-based, and Analog.

Phase noise is caused by a signal’s random phase fluctuations and can significantly affect the performance of wireless systems. Highly accurate, reliable, and flexible phase noise analysis is therefore critical to ensure advanced systems operate as expected. In this demonstration, learn how to measure the phase noise of a 100 MHz oven-controlled crystal oscillator (OCXO) using the Holzworth HA7062D Real-Time Phase Noise Analyzer.
