RF Signal Generators for Receiver, Transceiver, and Component Test

XGY Tek supplies portable, benchtop, and modular RF signal generators to labs worldwide working on 5G, satellite, radar, and aerospace programs. The portfolio spans CW stimulus, vector modulation, and low-phase-noise frequency references from 9 kHz to 44 GHz. All units ship with traceable calibration and are supported by RF engineers based in Adelaide and Sydney.

What signal generators does XGY Tek offer?

Our catalogue includes the YSG-P400 series portable RF signal generators (9 kHz – 44 GHz) for field receiver test and remote stimulus; the YSG-400B and YSG-5451 benchtop sources for laboratory R&D with vector modulation, pulse shaping, and IQ streaming; and the YSG-140 low-phase-noise frequency source for clean local-oscillator and reference clock duty. PXIe-based signal sources are also available through our modular test instruments line.

When do I need a low-phase-noise frequency source like the YSG-140?

Low-phase-noise sources are required whenever phase noise on the LO directly limits the measurement floor — receiver sensitivity, radar Doppler resolution, jitter-sensitive ADC clocking, and atomic-clock or quantum-readout chains. The YSG-140 is engineered specifically for these workloads, delivering reference-grade phase noise that lets your spectrum analyzer or VNA hit its rated performance rather than inheriting source noise.

Can XGY signal generators integrate with existing test rigs?

Yes — all XGY signal generators expose standard SCPI command interfaces and ship with Windows and Linux integration libraries. Python and LabVIEW drivers are available, and the units can serve as drop-in replacements for legacy Keysight or R&S sources in most automated test scripts.
