The Agilent/Keysight Technologies M9331A 10-bit, 1.25 GS/s Arbitrary Waveform Generator, Refurbished (AWG) capable of creating digitally modulated waveforms for wideband communication systems. Each channel of the M9331A operates at 1.25 GS/s and features 10 bits of vertical resolution, which is ideal for compliance testing of digital radios targeted for use with emerging communication standards such as MB-OFDM ultra wideband, 802.11n, MIMO, and proprietary wideband formats.

Generate Wide Bandwidth AND Low EVM Signals, Simultaneously

The M9331A is a 4 slot 3U PXI module that offers dual differential output channels to drive both single-ended and balanced designs. The AWG also supports advanced sequencing and triggering modes to create event-based signal simulations. Multiple M9331A modules can be synchronized for the generation of phase-coherent, multi-emitter scenarios. Waveform development tasks are simpliied using the AWG's numerous programmatic interfaces including complete instrument control from the MATLAB® command line and from LabVIEW.

Extended performance

The M9331A gives designers access to Digital-to-Analog Converter (DAC) technology capable of generating wideband digital communications signals with ultra-low EVM. Each module incorporates two high-speed DACs to create 500 MHz of signal bandwidth and ≤ -50 dBc SFDR across each channel. Users have the choice of driving their designs differentially from the DAC outputs or through multiple signal-conditioning paths. Although some AWGs require users to make a trade-off between the number of output channels and differential outputs, the M9331A provides both-allowing you to drive your designs and eliminating the need for baluns or hybrids in the test path. In addition, each channel can output waveforms as an IF or as a baseband signal for I/Q upconversion.

Uniquely define how waveform Create long scenario simulations Multiply the effective size of on-board memory through the use of the M9331A's advanced sequencing engine. Uniquely define how waveform segments are played through looping and nesting of stored waveform models. This capability gives users the ability to simulate fading and other multi-path effects for extended periods of time. For users developing a large number of propagation models the PXI backplane substantially reduces waveform download times compared to traditional LAN and GPIB interfaces. The M9331A's complete waveform and sequencer memories can be typically reloaded in less than 1 second.

System stability

Create phase-coherent, multiemitter simulations using the M9331A's precision SYNC clock. A single M9331A can drive a total of eight AWG modules to synchronize their outputs on a sample-by-samplebasis. Any number modules can be synchronized with simple driver hardware. The AWG also includes multiple front-panel trigger and markers for complete system synchronization.

Ease-of-use

The M9331A's graphical user interface guides developers through module setup and waveform file transfers. Users can quickly configure the instrument's signal conditioning paths, marker and trigger lines, sample and reference clock sources and simple sequencing functions. More sophisticated sequencing functions are available through the instrument's numerous programmatic interfaces. The M9331A supports interfaces for MATLAB®, LabView, IVI-C, IVI-COM, and VEE framework.
