81150A and 81160A Pulse Function Arbitrary Noise Generators

Introduction

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

Today‘s Challenges Require a New Generation of Test Instruments

You are under pressure to get products to market faster and faster, with shrinking design schedules and increasing quality goals. The pressure is never ending. Because differentiation means survival in the marketplace, you often have to test unique functionality. Being confident in your results takes highly adaptable and efficient testing.

Such challenges require a new generation of test instruments, which are:

• Accurate, to test your device and not your source
• Versatile, to be ready for today’s and tomorrows test challenges
• Plug and play solutions, with minimal cabling, low space overhead and have many functions built-in

Whichever way you look at it, this starts with accurate, versatile and uncompromising signal sources.

Keysight’s offering

Just test – with the signal you need.

Quad versatility – optimum signal fidelity

The Keysight Technologies, Inc. 81150A and 81160A Pulse Function Arbitrary Noise Generators set the standard for the next generation of lab: for fast, accurate insight into your design or device under test. Both of them offer:

• Pulse generators with precise signals for performance verification and characterization function arbitrary generator For versatile signal generation to optimize testing
• For modulation to shape the signal the DUT needs
• A noise generator to distort signals to build up worst case scenarios
• An optional pattern generator to test in addition to analog, digital and mixed signal devices with ideal and real-world conditions

The Keysight 81150A and the new Keysight 81160A Pulse Function Arbitrary Noise Generators are indispensable contributors to accelerate ideal and real-world testing.

Pulse Generator – Test Your Device and Not Your Source

Superior precision pulses with unbeatable timing stability guarantee reproducible tests. The signal quality and trigger functionality provide everything you need for trigger or system clock applications.

You can change the timing parameters (delay, frequency, transition time, width, duty cycle) without dropouts or glitches. This patented, industry-leading feature means continuous operation without having to reboot or reset your device under test, for example when you are characterizing a device by sweeping the clock frequency. Apart from full control of the timing parameters, you can also adjust levels and edges as needed.

Set up complex measurements

Both, the Keysight 81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generator, are available in a 1- or 2-channel version. On the two-channel version, the channels can be uncoupled, to work independently, or coupled, for example, with a defined delay between them.

Each channel provides Trigger Out, Strobe Out and differential outputs: the basis for many complex test setups.

Function Arbitrary Generator

If you need further signal conditioning, the Keysight 81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generators provide versatile waveforms and modulation capabilities to adapt your signal to your device’s requirements. AM, FM, FSK, PM and PWM are available at modulation frequencies up to 10 MHz and to 50 MHz.

The Keysight 81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generators can use internal or external modulation sources. Internal modulation can be generated from the 2nd channel or the internal modulation source of the modulated channel.

Noise generator – repeatable and stochastic noise

Jitter and noise cause misalignment of edges and levels, resulting in data errors. Noise is by its nature unpredictable because it can have many different causes, from signal interference caused by sudden voltage changes, to distortions introduced during transmission.

It is important to be able to simulate noise-based malfunctions, for example, to identify the additive noise produced by receiving systems—it is cheaper to lower the noise figure than to increase the transmitter power! The Keysight 81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generators let you control the quality of the noise, to test different cases, and according to various specifications.

White Gaussian noise is a good approximation to many real-world situations, and creates mathematically traceable models, with statistical independent values. The Keysight 81150A and the Keysight 81160A Pulse Function Arbitrary Noise Generators provide deterministic white Gaussian noise, with a signal repetition of 20 days or 26 days respectively. You can decide on any arbitrary distribution, and trigger the noise to start when you need it.

Pattern Generator – Test in Addition to Analog, Digital and Mixed Signal Devices

Engineers working with serial buses or designers of analog, digital and mixed signal devices require stressing their design with pattern. The optional Keysight 81150A and 81160A arbitrary bit shaped pattern generator allows sending ideal and real-world pattern. The Keysight 81150A with arbitrary bit shaped pattern (Option PAT) allows emulating overshoot, asymmetric delay and duty cycle distortion up to 120 Mbit/s, the Keysight 81160A up to 330 Mbit/s (Option 330) or even up to 660 Mbit/s (Option 660). Patterns can be easily set up and distorted at your fingertips.
