  8. Holzworth Cross Correlation In Phase Noise Analysis 4/26/2011

    Cross correlation is a method used in phase noise analysis to extend the range of any single channel measurement by introducing a second channel and utilizing signal processing to locate the noise that is common to the DUT, yet uncommon to each individual channel. This article presents the mathematics with an example of how cross correlation can accurately identify signals or noise that is below the level of the measurement instrument. 

  9. Coherent Multi-Channel RF Synthesis 4/7/2010

    Holzworth Instrumentation is a provider of high-performance, multi-channel RF synthesizers that are known for ultra low phase noise performance. In addition, these non-PLL based synthesizers have unique phase characteristics, which add great value to certain applications. This article addresses some frequently asked questions about multi-channel synthesis and provides insight to the engineering trade-offs that go into a synthesizer design.

  10. Phase Coherent Multi-Channel RF Synthesis 9/23/2009

    Multi-channel synthesis applications require specific performance parameters that are often overlooked with the design of single channel synthesizer systems. Performance specifications for multi-channel synthesis applications typically require channel to channel, short and long term phase coherence that is not possible with phase-locking an N-number of single channel synthesizers together. This configuration only creates a long term phase-lock ‘average’ between the outputs. Each individual synthesizer also contributes to the short term stability of this system, which is problematic with traditional phase locked synthesizers.
