81150A and 81160A Pulse Function Arbitrary Noise Generators

Technical Overviews

High precision pulse generators enhanced with versatile signal generation, modulation and distortion capabilities for:

· Accurate signals to test your device and not your signal source

· Versatile waveform and noise generation to be ready for today‘s and tomor­row‘s stress test challenges

·  Optional pattern generator to test in addition to analog, digital and mixed signal devices

· Integrated into one instrument to minimize cabling, space and test time

Introduction

Keysight Technologies, Inc. pulse generators are focused on high signal integrity to provide clear, stable and repetitive signals. This is required for all kinds of DUT development in R&D, followed by dedicated stress test with distorted and real world signals. A key and unique feature of the Keysight 81150A and 81160A Pulse Function Arbitrary Noise Generators is to combine two independent output channels. There are two ways of doing this. Either couple the channels or add the channels together.

Coupling between channels

In this lab it is shown how two channels can be coupled, so that the instrument behaves like a two-channel instrument with only one timebase. As a result of coupling, the output function and all other parameters like burst, sweep and modulation are also kept identical.

The very first task you should always perform, is to reset the instrument to default settings (‘STORE/RECALL’ and ‘SET TO DEFAULTS’).

Channel adding (this requires a two channel instrument)

In this exercise we add the output signals of the two independent output chan­nels together. This is the only way to generate distorted signals out of standard waveforms. Even more flexibility is provided when using Arb based signals on one channel.

Please reset the instrument to default settings (‘STORE/RECALL’ and ‘SET TO DEFAULTS’).

How to generate customer based waveforms and add noise

Keysight pulse generators are focused on high signal integrity to provide clear, stable and repetitive signals. Individual and customer based signals can stimu­late real world stress tests. Very often specific setups and circumstances lead to abnormal behaviors of DUTs. This behavior is seen and can be measured by oscilloscopes.

A key feature of the Keysight 81150A and 81160A Pulse Function Arbitrary Noise Generators is to define individual signals and also to provide signals which are filed by an oscilloscope. The third way to generate specific wave forms is to use the Keysight 33503A Benchlink Waveform Builder Pro software which runs on every PC.
