Visualization & Validation

The mathematical, predictable nature of signals generated by AWGs makes them ideal for degradation analysis. ArbIQ incorporates a bunch of analysis tools and features that can be used as a reference to be compared with results coming out of measurement instruments such as oscilloscopes, spectrum analyzers, or vector signal analyzers (VSAs).

Graphs and analysis windows are also useful for documentation or educational purposes. Additionally, ArbIQ, through an option, is capable of exporting signals in a variety of formats that can be read by spreadsheet applications such as Excel, or scientific/ mathematical packages such as Matlab for further analysis, manipulation, and/or documentation.

Analysis Tools

Phase/Constellation Diagrams

The Constellation Diagram is the primary validation and analysis tool for digitally modulated signals. Signal trajectory between symbols is also shown.

Eye Diagram

Signal evolution in the time domain may be observed from the statistical or real-time standpoint. Eye digarams are shown for the I and Q components.

CCDF

The CCDF curve is a very useful tool to validate the distribution of power over time. Usage of cursors eases the comparison with measuring instruments.

Histogram Analysis

Grey scale display and histogram analysis in the IQ plane helps to pinpoint coding or data related issues when not all symbols are equally probable.

Spectrum

Spectrum analysis is the most useful tool to analyze the distribution of multi-carrier signals or the effects of non-linearities in the frequency doamin.
