Technical Overview
The Keysight Technologies, Inc. spectrum visualizer (ASV) software provides advanced FFT frequency domain analysis for the InfiniiVision and Infiniium Series high performance oscilloscopes at a cost-effective price. The ASV software extends the InfiniiVision and Infiniium Series oscilloscopes to perform frequency-domain FFT analysis. It provides spectrum and spectrogram analysis with an intuitive user interface, parameter and control settings, and marker functionality that RF engineers are familiar with, offering advantages over traditional oscilloscope FFT solutions. This new capability helps engineers gain greater insight into their design performance and helps engineers debug issues faster when they occur.
Features and benefits:
Select from a wide range of frequency domain measurement capabilities, utilizing the Frequency, Analog, and Spectrogram views.

Gain Insight into Performance Issues Quickly Using the ASV Software with
InfiniiVision and Infiniium Series Oscilloscopes
Using oscilloscopes for time domain analysis may only provide part of the information needed to understand and debug issues when they occur. Measuring the frequency domain characteristics, in addition to the time domain characteristics, can quickly reveal important information about the hardware performance, functionality, and potential issues that may arise and can accelerate hardware debug by providing greater insight into performance issues.
An example is a phase-locked loop (PLL) circuit, where the output of the PLL is being tuned for a given output frequency or range of frequencies. While it may be fairly straightforward to determine a PLLs static fundamental output frequency by using a time-domain analysis approach on an oscilloscope and measuring the period (ΔT) to calculate the frequency (F=1/(ΔT), it can be relatively difficult to tell what the PLL’s output spectral purity is or the PLL’s frequency domain response is without measuring the PLLs frequency domain performance.
In addition, given the complexity of testing and debugging today’s commercial wireless and military radios, another example might be evaluating the frequency hopping characteristics of a frequency-hopped radio, or the frequency shift keying (FSK) of a GFSK (Gaussian FSK) radio such as Bluetooth®. A more advanced example might be measuring the spectral characteristics of an orthogonal frequency division multiplexing (OFDM) radio to determine the occupied frequency bandwidth for a given number of subcarriers allocated.
These types of issues can be very difficult to evaluate without using frequency domain analysis.
An actual example is shown below, with a frequency shift keying (FSK) signal being measured and analyzed with the ASV software on an InfiniiVision 3000 X-Series oscilloscope.
