Product Introduction

SigVSA Vector Signal Analysis software brings professional vector signal analysis capabilities to engineers’ desktops. It supports both Windows and Linux operating systems, enabling users to repeatedly analyze signals and quickly identify issues. It covers a comprehensive range of measurement requirements, from basic BPSK to complex wideband signals such as FHSS, IQA, UWB, DMA, OFDM, 4G LTE, 5G NR, IEEE 802.11b/a/g/n/ac/ax/be, and 4096QAM.

Key Features

  • Offline waveform data analysis on PC
  • Multiple IQ data formats
  • Supports the maximum 2G analysis bandwidth of the specified signal.
  • Support general OFDM signal analysis
  • Signal analysis supporting cellular protocols such as 4G LTE and 5G NR.
  • Support a variety of general modulation signal analysis.
  • Support WLAN standard signal analysis such as IEEE802.11b/a/g/n/ac/ax/be.
  • Support online control of multi-instrument acquisition, and obtain waveform data to PC for analysis.
  • Support simultaneous control of multiple instruments and equipment for parallel vector analysis, and multiple applications can be displayed independently, which is convenient and clear.
