BandwidthModular Arbitrary Waveform Generators
Keysight modular arbitrary waveform generators (AWGs) offer high-performance, scalable signal generation for higher-level testing in high-speed digital, RF, and optical applications. For modular, space-efficient systems with many synchronized channels in environments like manufacturing test, PXIe AWGs are ideal — they fit into smaller chassis and support high-density setups in a limited rack space. For ultra-high sampling rates, high bandwidth, and exceptional signal fidelity, AXIe AWGs deliver up to 256 GSa/s and 80 GHz bandwidth with low phase noise and jitter, making them well-suited for cutting-edge research in next-generation wireless and optical communications. With multiple models available, choose the right modular AWG for your application.
Modular architecture
Supports high channel density and scalability for multichannel applications like quantum computing, beamforming in phased array radar, and 5G, 6G, and Wi-Fi 6 / 7 testing.
Channel synchronization
Generate and control multiple independent waveform outputs that require precise timing, phase alignment, and coherence across multiple signal channels.
Enhanced sequencing
Dynamically control the playback order, timing, and conditions under which waveform segments are played to emulate real-world, time-varying signal environments.
Signal generation software
Create, customize, and control complex waveforms, from standards-compliant signals like 5G to terabit transmission — without writing any code.
Modular Waveform Generators
Keysight modular PXIe waveform generators offer precise, repeatable signal generation for digital interface testing, protocol emulation, and system validation. Unlike arbitrary waveform generators, which focus on complex, user-defined signal synthesis across RF and optical domains, modular waveform generators are optimized for deterministic playback of structured waveforms with tight timing control. Compared to benchtop models, modular models provide higher channel density, better synchronization across multiple outputs, and integration into modular PXI test systems.
Pulse Generators
Keysight PW1-class Pulse Generators include the 81100A Series. They deliver high-speed pulse signals with picosecond-level timing precision and low signal distortion. They provide finely controlled pulse and pattern signals with extremely fast edge transitions, low intrinsic jitter, and programmable voltage levels, making them well-suited for generating clock, trigger, and data signals in high-speed digital and mixed-signal test environments. With flexible triggering, enhanced timing control, and remote programmability, they can emulate real-world signal conditions and enable you to perform timing margin analysis.

Frequently asked questions
A function generator is an electronic test equipment that generates standard waveforms, such as sine, square, ramp, or sawtooth waves, to a device under test (DUT). In circuit design and boards, testing often requires a controllable signal to simulate regular operation. Testing physical systems and transducers often requires stable and reliable signals ranging from microvolts to tens of volts or more.
By providing a stimulus or known input signal, you can see what happens to a device under different conditions. You can evaluate the DUT’s performance by inputting a known-good signal into the DUT and monitoring the output. The waveform generator output must be clean and stable, and it should represent the real signals that the device’s final application will use.
A pulse generator is an electronic test instrument designed to create electrical pulses with highly controlled characteristics such as width, amplitude, frequency, and rise or fall times. These pulses are typically sharp and well-defined, making them ideal for testing digital circuits, timing behavior, and high-speed electronic systems. Engineers often use pulse generators to simulate clock signals, trigger other instruments, or evaluate how a circuit responds to sudden changes. Because of their precision, pulse generators are essential in applications like communications, semiconductor testing, and signal integrity analysis.
