Keysight Test Automation on PathWave (TAP) is a modern Microsoft .NET-based application for standalone use or in combination with higher level test executive software environments. Instrument plug-ins provide test steps that can be added to work-flow sequences without instrument level programming commands. The LCA plug-in steps further simplify automation by handling the interface to both the PNA instrument and the LCA optical hardware and software and providing the test steps for easy configuration.

Standalone Software for Analysis of Complex Modulated Optical Signals

The analysis software from Keysight’s optical modulation analyzer (OMA) portfolio can be used on your PC without any instrumentation. It offers analysis capabilities such as advanced signal processing algorithms for complex modulated optical signals.

Use this software to process and analyze raw data stored as .sdf, .mat, or .csv files from measurements with any Keysight OMA This capability allows you to work with the data as if you were working directly in front of the instrument. Develop your own signal processing algorithms and test them offline, together with your MATLAB compiler. In addition, this software is an effective tool for learning basic and advanced concepts of complex optical modulation, based on stored files.

Benefits of a standalone software installation include the following:

• post-process recordings with various analysis parameters for your presentation without blocking the hardware
• hands-on learning about complex optical transmission
• offline use of Keysight's signal processing algorithm

Benefits of the scope hardware connection include the following:

• Analyze your own receiver hardware in combination with a Keysight UXR-series, Z-series, or 90000 series real-time oscilloscope and OMA vector analysis software.
• Get access to receiver calibration values (skew, gain imbalance, and so on) for evaluating sensitivity to these parameters.
• Test your own IQ hybrid under real application conditions.

The time domain capability allows you to measure the time domain response of a device. The analyzer can transform frequency domain data to the time domain or time domain data to the frequency domain.

The transform used by the analyzer resembles time domain reflectometry (TDR) measurements. TDR measurements, however, are made by launching an impulse or step into the test device and observing the response in time with a receiver similar to an oscilloscope. In contrast, the analyzer makes swept frequency response measurements, and mathematically transforms the data into a time domain reflectometer-like display.

The S97010B software is compatible with the Keysight Streamline Series Vector Network Analyzers.
