Keysight Pro Signal Generators

Videos

This video introduces Keysight Pro Vector Signal Generators (VSGs), designed to deliver the highest performance in Keysight’s signal‑generation portfolio for next‑generation wireless, aerospace, satellite, and advanced RF system development. Pro VSGs generate extremely high‑frequency signals—up to 54 GHz natively, or 110 GHz with frequency extenders—and offer up to 2.5 GHz of modulation bandwidth. Built on a direct digital synthesis (DDS) architecture, they provide exceptional spectral purity, low phase noise, and precise frequency control for mission‑critical applications. These generators support embedded signal creation, real‑time fading, and multi‑carrier emulation for validating 5G NR, Wi‑Fi, GNSS, and advanced multi‑antenna systems.


Pro VSGs enable high‑performance channel emulation with up to four synchronized and phase‑coherent RF channels, plus eight virtual signal generators per RF channel—supporting up to 32 emulated transmitters in one instrument. This architecture simplifies MIMO, beamforming, and link‑level evaluations. Channel bonding enables up to 5 GHz of aggregated bandwidth for validating ultra‑wideband communication systems. Real‑time fading with custom fading models supports 3GPP‑compliant 5G NR conformance testing as well as advanced propagation‑environment simulation.


Keysight’s custom ASICs and DDS technology deliver ultra‑low phase noise, reaching –148 dBc/Hz, enabling precise LO synthesis and minimizing measurement uncertainty for highly sensitive radar, satellite, and high‑frequency oscillator applications. Embedded software enables real‑time generation of wideband uplink signals, LTE/5G waveforms, GNSS signals, and complex fading scenarios directly from the touchscreen interface without external processing hardware. With unmatched bandwidth, output power, multi‑channel capability, and low‑noise performance, Pro VSGs provide a future‑ready platform for advanced wireless research and next‑generation communications testing.
 

Key features include:

  • Ultra‑High Frequency: Generate signals up to 54 GHz, or 110 GHz with a frequency extender, supporting all 5G NR bands and V/W‑band applications.
  • Multi‑Channel Emulation: Emulate up to 32 virtual transmitters with four synchronized, phase‑coherent RF channels and eight virtual emulators per channel.
  • Real‑Time Signal Generation: Produce real‑time signals for 5G NR, LTE uplink, GNSS, and 3GPP‑compliant fading for base‑station testing.
  • Ultra‑Low Phase Noise: Keysight custom ASICs and DDS deliver –148 dBc/Hz phase noise with extremely fine frequency resolution.
  • Wide Modulation Bandwidth: Achieve up to 2.5 GHz modulation bandwidth and up to 5 GHz aggregated bandwidth through channel bonding.
     

Pro Vector Signal Generators provide unmatched bandwidth, frequency coverage, spectral purity, and multi‑channel capability for cutting‑edge RF and wireless system development. Engineers working on aerospace, defense, satellite, and next‑generation communication systems rely on Pro VSGs for accurate, flexible, and high‑performance signal creation.
