Status do Produto: Descontinuado | Com Suporte
Este produto não se encontra disponível

Principais recursos e especificações

  • Analyze and visualize I/Q modulation with confidence and simplicity
  • A variety of measurement displays help to detect the most common types of errors
  • A quantitative measure, available through the comprehensive results table, helps define errors
  • A symbol dot feature helps to locate errors. Dots can be activated to identify the symbol locations in conjunction with traces - pattern in the errors will help pinpoint the cause of the error
  • One-button switching between popular format configurations
  • Easy-to-use display tools (eye, constellation, and vector diagrams) help speed troubleshooting
  • User-selectable demodulation format, filtering, and symbol rate, with an intuitive measurement-setup environment
  • Built-in help key for quick reference without manuals


The Keysight ESA-E series spectrum analyzers with the modulation analysis measurement personality (Option 229) provides the flexibility of general-purpose spectrum analysis combined with numerical and visual tools to help quickly identify and quantify impairments to digitally modulated signals for all major cellular standards. Essentially, the ESA-E now provides spectrum and vector measurements in one measurement tool, thus reducing the need for additional equipment, preserving measurement accuracy, and minimizing system development time.

Vector modulation analysis can be performed on any signal that uses a QPSK, OQPSK, II/4 DQPSK or EDGE (8PSK) baseband modulation format. Included cellular standards are cdmaOne, cdma2000, W-CDMA, NADC, EDGE, PDC and TETRA.

The modulation analysis measurement personality for the ESA-E series spectrum analyzers allows you to measure the most widely used modulation quality metric in digital communications systems, Error Vector Magnitude (EVM). EVM related metrics includes, I/Q magnitude, I/Q phase, I/Q frequency, I/Q offset (carrier feed-through), and amplitude droop. Display tools include I and Q eye diagrams, polar vector and constellation, magnitude error versus symbol display, phase error versus symbol display and EVM versus symbol display.

This option can be added as a product upgrade.
