Spectrum Analyzers

Spectrum Analyzers for RF, EMC, and 5G Testing in Australia

XGY Tek supplies handheld, USB-based, networked, and benchtop spectrum analyzers to engineering teams worldwide across telecom, defense, automotive, EMC, radar, and university research. The YSA-P400 series covers 9 kHz to 40 GHz with -161 dBm/Hz DANL in a 1.5 kg handheld form factor, 100 MHz real-time bandwidth, and 100% POI to 15 us for field interference hunting and EMC pre-compliance.

The YSA-N400 suits fixed bench, benchtop, rack-adjacent, or remote monitoring roles, while the YSA-U090 is a compact USB RTSA choice when 9 kHz to 9 GHz coverage is enough. A credible measurement record should include frequency span, RBW, VBW, detector, attenuation, preamp state, antenna or probe, calibration status, screenshot, raw trace export, site note, and instrument serial number.

For model selection, see our spectrum analyzer selection guide. Calibration documentation and RF support scope are confirmed during quotation.

Frequently Asked Questions

Which XGY model is the fixed benchtop spectrum analyzer?
The YSA-N400 networked spectrum analyzer is the fixed-bench and rack-adjacent choice. It publishes the same 9 kHz to 40 GHz ceiling and 100 MHz real-time bandwidth as the handheld YSA-P400, so the decision is primarily fixed host control and integration versus an integrated field instrument. The YSA-U090 USB analyzer is the smaller host-controlled option when 9 GHz coverage is sufficient.
Does 40 GHz coverage automatically fit every 5G measurement?
No. Choose the YSA-P400 or YSA-N400 only when every carrier, span, harmonic, and out-of-band check in the written test plan remains within the published 40 GHz ceiling. If the required measurement extends above 40 GHz, the current published YSA models are not a complete fit. For work at or below 9 GHz, compare the USB YSA-U090 before specifying a 40 GHz instrument.
Which spectrum analyzer should I choose - handheld, USB, or benchtop?
Handheld units (YSA-P400 series) are the right pick when measurements must happen on-site - rooftops, masts, radar ranges, EMC chambers - and you want benchtop-class performance in a battery-powered tool. USB analyzers (YSA-U090 series) are ideal for compact lab benches and headless automated setups driven by Python or LabVIEW. The benchtop YSA-N400 series suits production lines and dedicated R&D rigs where rack space is available and uptime matters. Our team in Adelaide can help you size POI, RBW, and DANL against your application - request a quote with your test plan.
What measurements can XGY spectrum analyzers perform?
XGY spectrum analyzers cover spurious and harmonic analysis, channel power, ACPR, OBW, EVM and digital demodulation (ASK/FSK/PSK/QAM with constellation, eye diagrams), real-time persistence and density displays, phase-noise measurement (-107.5 dBc/Hz at 1 GHz on the YSA-P400), and IQ streaming for post-capture processing. Typical workloads include 5G NR FR1/FR2 conformance, radar pulse analysis, EMC pre-compliance (CISPR/MIL-STD-461 with our RF accessories), and aerospace/defense receiver test.
Do XGY spectrum analyzers ship with calibration and warranty?
Calibration documentation, warranty terms, re-calibration options, on-site commissioning, and Python/LabVIEW automation scripting are confirmed during quotation or through our Custom Automation service. For turnkey EMC pre-compliance benches that pair an analyzer with an EM5040 LISN, RF cables, and a control PC, review the EMC pre-compliance setup checklist, then contact our team via the quote form.
What should be saved with an interference-hunting result?
Save a screenshot, raw trace, time and location, antenna or probe type, frequency span, RBW/VBW, detector, attenuation, preamp state, calibration status, and instrument serial number. That makes the result reproducible.
When is 100 MHz real-time bandwidth important?
It matters for short pulses, hopping signals, radar events, bursty emissions, and intermittent interference where swept-only analysis may miss the event or misrepresent occupancy.
