z8752 VSG

Vector Signal Generator PXIe

The z8752 Vector Signal Generator combines a baseband I/Q Arbitrary Waveform Generator with an RF signal source to generate vector modulated signals from DC to 7.2 GHz to characterize high performance PAs.

The VSG provides a combination of 500 MHz modulation bandwidth, 16-bit DAC dynamic range, very high linearity and extremely low phase noise necessary to test and characterize devices operating on existing and the emerging WLAN standard 802.11ax (Wi-Fi 6).


  • Reduced test time through fast RF switching (<1 msec end to end) and deep multiple-waveform memory
  • Extremely low phase noise <-110 dBc/Hz
  • Vector signal generation for analog or digitally-modulated RF signal


  • Power Amplifier/Front End Module characterization and DVT
  • Receiver Packet Error Rate (PER) analysis
  • Radio Frequency Integrated Circuit (RFIC) testing
  • Digital Pre-Distortion (DPD) Waveform Generation

Key Specifications

  • Multi band support 2.4 GHz, 5 GHz, U-NII-4/5/6/7/8 with comprehensive range of operation from 250 MHz – 7.2 GHz
  • Supports up to 500 MHz modulation bandwidth
  • LO input for ultra-low phase noise requirements
  • Separate baseband I/Q outputs and LO input for modulator RFIC testing (optimized for broad bandwidth vector modulation)

Remarkable Test Capabilities

  • Ideal for MIMO applications (up to 8×8 true MIMO in a single zSeries 18-slot chassis)
  • Comprehensive testing capability on all Modulation and coding schemes (MCS) – BPSK up to 1024-QAM
  • Supports all Modulation Bandwidths: 160 MHz, 80 MHz, 40 MHz & 20 MHz


Frequently used with:

  • z8655 Vector Signal Analyzer
  • z8817 Front-End Module
  • zSeries 9-slot or 18-slot chassis
  • z3975/z3985 Embedded Controller (Intel Core i5/i7 processor)
  • z8820 DC Power & Digital IO Controller
  • z475 Remote DC Power supply
  • z8801/z8802 Local Oscillator

All solutions are adaptable and re-configurable to provide you with the greatest flexibility for your testing requirements.
