Simplifies Frequency Analysis
An oscilloscope provides powerful capability to debug frequency-related effects. Fast Fourier Transforms (FFTs) have long been part of oscilloscope toolboxes. Now, Spectrum Analyzerlike capability is available to simplify setup and use of the oscilloscope for analyzing frequency-dependent effects. It allows users who are familiar with RF spectrum analyzers to start using the FFT with little or no concern about the details of setting up an FFT.
Setup is simple—select a center frequency, span, and resolution bandwidth and the necessary sample rate and time-domain acquisition length are automatically determined. Then, select an operational mode (Normal, Average, or Max Hold) for the spectrum display. Other settings for reference level and scale may also be made. With the Spectrum Analyzer and Advanced FFT option, the user is freed from the need to translate scope sample rate, memory, and acquisition length settings into frequency domain relevant units.
Table of Frequency Peaks
“Show Peaks” labels and tabulates spectrum frequency peaks and lists them with amplitude values ordered from highest to lowest. Simply touch one of the peaks to zoom the spectrum display for a closer look. The table also makes apparent frequency peaks that you may not have otherwise noticed.
Highest Resolution Bandwidth and Fastest Processing Time
LeCroy provides capability to process even very long acquisitions quickly and achieve the highest resolution bandwidth possible with X-Stream II processing in Zi Series oscilloscopes. This means more effective debugging, and a quicker time to debug.
Includes Advanced FFT Features
In addition the the Spectrum Analysis capability, the option also provides advanced FFT capability, such as power spectrum density, real/imaginary, and magnitude squared frequency analysis, either through the Spectrum Analyzer or using an FFT math function.
