Data Sheets

Be Ready for Tomorrow — Today

RF requirements keep growing while timelines keep shrinking. To help ease the technical and business pressures, the right test solution provides continuity in measurements and longevity in capability. The Keysight Technologies, Inc. M9381A PXIe vector signal generator (PXI VSG) is the next logical step in RF signal generation. To get proven results even faster, use Keysight software with the PXI VSG to create the test stimulus you need to validate and test your RF communications designs. Signal Studio and Waveform Creator software simplify and streamline signal creation and generation from basic analog and digital modulation to the latest wireless standards like LTE-Advanced and 802.11ac WLAN. Combine the M9381A PXI VSG with the M9391A PXIe vector signal analyzer for a complete solution for fast, high quality measurements optimized for RF manufacturing test environments. From fully modular hardware to software leverage to worldwide support, the PXI VSG is the low-risk way to manage change and be ready for tomorrow — today.

Product description

The M9381A PXIe vector signal generator (PXI VSG) is a compact modular instrument that provides frequency coverage from 1 MHz to 6 GHz and up to 160 MHz RF modulation bandwidth. The M9381A is comprised of four individual PXIe modules — M9311A modulator, M9310A source output, M9301A synthesizer, and M9300A frequency reference. A single M9300A frequency reference can be shared between multiple instruments to minimize footprint. A wide range of instrument drivers are available to support your development environment of choice. The flexible, modular design of the M9381A enables you to efficiently scale to multi-channel signal generation to test multiple-input, multiple-output (MIMO) devices. Many capability options such as memory, frequency range and modulation bandwidth can also be easily upgraded in the field.

Applications

  • Power amplifier and front-end-module design validation and manufacturing
  • Radio transceiver design validation and production test
  • MIMO and multi-channel device test

Technical Specifications and Characteristics

Definitions for specifications

Temperatures referred to in this document are defined as follows:

  • Full temperature range = Individual module temperature of ≤ 75 °C as reported by the module, and environment temperature of 0 to 55 °C
  • Controlled temperature range = Individual module temperature of ≤ 55 °C as reported by the module, and environment temperature of 20 to 30 °C

Specifications describe the warranted performance of calibrated instruments. Data represented in this document are specifications under the following conditions unless otherwise noted.

  • Calibrated instruments have been stored for a minimum of 2 hours within the full temperature range
  • 45-minute warm-up time
  • Calibration cycle maintained
  • When used with Keysight M9300A frequency reference and Keysight interconnect cables

Characteristics describe product performance that is useful in the application of the product. Characteristics are often referred to as Typical or Nominal values and are italicized.

  • Typical describes characteristic performance, which 80% of instruments will meet when operated within the controlled temperature range
  • Nominal describes representative performance that is useful in the application of the product when operated within the controlled temperature range

Recommended best practices in use

  • Use slot blockers and EMC filler panels in empty module slots to ensure proper operating temperatures. Keysight chassis and slot blockers optimize module temperature performance and reliability of test
  • Set chassis fan to high at environmental temperatures above 45 °C
  • Maintain temperature stability for best multi-channel phase coherence
  • Set chassis fans to maximum
  • Maintain stable ambient temperature
  • Perform warm-up with session open and representative waveform running

Additional information

  • Specifications use the normal PLL mode setting, unless otherwise stated. Narrow loop bandwidth refers to specifications using the best wide offset PLL mode setting AGM938X_VAL_SYNTHESIZER_PLL_MODE_BEST_WIDE_OFFSET, available in the M938x Vector Signal Generator/CW Source Instrument Drivers versions 1.2.300 and later
  • Performance described in this document applies for mod[1]ule temperature within ± 5 degrees of IQ alignment, unless otherwise noted
  • When configured for multi-channel, phase-coherent operation (shared synthesizer configuration), instrument level warranted specifications only apply to the M9381A which was previously calibrated with the M9301A synthesizer, showing a valid calibration indicator. For all other M9381A channels, specifications revert to typical performance. If using an ex[1]ternal LO distribution unit, such as the V2802A LO distribution network, specifications for all M9381A channels revert to typical performance
  • All graphs contain measured data from one unit and are representative of product performance within the controlled temperature range unless otherwise noted.
  • The specifications contained in this document are subject to change
