Product Status: Discontinued | Currently Supported
This product is no longer available

No replacement found for this product.

Key Features & Specifications

Signal analysis

  • Standards supported: IEEE 802.11n HT (20 MHz, 40 MHz)
  • Modes: HT-greenfield, HT-mixed, non-HT duplicate, HT duplicate; up to 4x4 MIMO
  • Modulation formats: BPSK, QPSK, 16QAM, 64QAM
  • Preset to standard: 802.11n 20 MHz, 802.11n 40 MHz


  • Analyze overall signal quality with peak and RMS EVM, constellation, data burst, SIG info and more
  • Pinpoint signal impairments with EVM results for pilots, data, preamble fields, vs. time (symbol) and vs. frequency (carrier)
  • Evaluate time and frequency domain behavior with time, spectrum, CCDF, PDF traces for each channel
  • Detect automatically, or based on SIG symbols, the modulation format, number of spatial streams and result length

Other features

  • WLAN 802.11n/ac modulation analysis (Option BHJ) is also available and can replace this option B7Z.
  • Transportable license: resides on your PC/instrument, can be transported to another PC/instrument at any time
  • Also available as a Floating license: shared on a network server to be accessed by multiple users


The 89600 VSA software is a comprehensive set of tools for demodulation and vector signal analysis. Option B7Z was merged into option BHJ as 802.11n/ac modulation analysis after version 22.0. Option B7Z provided modulation analysis of WLAN 802.11n signals. With up to 4x4 MIMO signals, the flexible display and auto-detection of key signal parameters is essential in troubleshooting and evaluating 802.11n signals.
