UTS5000A-VSA: Vector Signal Analysis

Overview

The UTS5000A-VSA software option provides flexible vector signal analysis for custom and proprietary digital modulation schemes on the UTS5000A Series signal analyzer. Unlike standard-specific options (5G NR, LTE), VSA offers general-purpose demodulation tools for analyzing any digitally modulated signal—essential for satellite communications, digital microwave radios, proprietary wireless protocols, and RF component testing. With support for ASK, FSK, MSK, PSK, DPSK, and QAM modulation types up to 256-QAM, the VSA option delivers comprehensive digital signal characterization across the UTS5026A's full 9 kHz to 26.5 GHz frequency range.

Key Features

  • Comprehensive Modulation Support: ASK (2/4/8/16), FSK (2/4/8/16), MSK, PSK (BPSK/QPSK/OQPSK/8PSK), DPSK, and QAM (16/32/64/128/256)
  • EVM Measurement: RMS and peak Error Vector Magnitude for modulation quality assessment
  • Constellation Display: I/Q visualization with eye diagrams and phase tree diagrams
  • Flexible Filter Support: RRC, Gaussian, EDGE, CDMA, and Rectangular measurement and reference filters
  • Symbol Analysis: 10 to 4,096 measurement symbol length with adjustable over-sampling rates
  • Complete Error Statistics: Magnitude error, phase error, IQ offset, carrier offset, SNR, quadrature error, and gain imbalance
  • Multiple Display Formats: Logarithmic/linear amplitude, I/Q diagram, constellation, eye diagrams, phase diagrams
  • Software-Based: Can be added to existing UTS5000A analyzers via licensing

Frequently Asked Questions

What is the difference between the VSA option and the LTE/NR options?

The VSA option is a general-purpose vector signal analyzer that supports any digital modulation scheme (ASK, FSK, PSK, QAM, MSK, DPSK). It is designed for custom, proprietary, or non-standard signals. The LTE and NR options are standard-specific demodulators that provide 3GPP-compliant measurements including resource block analysis, channel-specific EVM, and predefined test models. If you work with standard 4G LTE or 5G NR signals, use the standard-specific options. If you work with proprietary protocols, satellite links, digital radios, or custom modulation, the VSA option is the right choice.

Can the VSA option be added after purchasing the analyzer?

Yes—the VSA option is software-based and can be added to any UTS5000A analyzer at any time through software licensing. Contact your UNI-T representative or authorized distributor for licensing and installation.

General-purpose vector signal analysis for any digital modulation—from ASK to 256-QAM.
