Frequently asked questions about Spectrum analysers
01
What is a spectrum analyser used for?It displays the frequency distribution of a signal, showing its power as a function of frequency. It is essential for analysing RF emissions, diagnosing interference or validating wireless transmissions.
02
What's the difference between a spectrum analyser and an oscilloscope?The oscilloscope shows a signal in the time domain, the spectrum analyser in the frequency domain. The latter is better suited to studying RF signals, EMC disturbances or emission spectra.
03
What are the technical criteria to be compared?The analysable frequency band, resolution bandwidth (RBW), amplitude accuracy, scanning speed, background noise level and measurement functions (EMI, demodulation, real-time analysis) are key.
04
Is a portable analyser enough for a field EMC audit?Yes, as long as it covers the target frequency band and has a preamp, an appropriate RBW filter and, ideally, a peak or quasi-peak detection mode. It must also be compatible with suitable antennas or probes.
05
Are refurbished spectrum analysers always up to date?This depends on the model and its use. If they are metrologically checked and include the necessary options (preamp, filters, firmware updates), they remain perfectly usable even in demanding use.

How to choose a reconditioned oscilloscope: 5 criteria that can't be mistaken
A reconditioned oscilloscope allows you to keep a bench operational, avoid manufacturer delays and control a technical budget without losing reliability. It's a useful solution when the aim is to quickly replace a critical device while retaining the same measurement procedures and compatibility with the existing equipment.
MBDA case study: how a reconditioned RF generator saved a critical test bench
In less than thirty days, Axitest secured two reconditioned Rohde & Schwarz RF generators for an MBDA test bench that had become unusable.
How do you choose your Keysight or Teledyne LeCroy oscilloscope for monitoring complex signals?
The two giants of electronic measurement, Keysight (direct heir to HP and Agilent) and Teledyne LeCroy, have occupied a central place in R&D, teaching and metrology laboratories for decades. But while their instruments may seem comparable, their philosophies and strengths differ profoundly. This article will help you to understand their differences...
Customer case study: quality control of electrical cables at LAPP MULLER using reconditioned equipment
In the electrical wiring industry, every continuity or insulation test determines the safety and performance of installations.
How to prepare for a COFRAC audit with reconditioned instruments: 6 key steps
A COFRAC audit is not just an administrative control; it is an examination of technical competence and metrological traceability. The use of reconditioned instruments is not an obstacle if each stage of preparation is controlled. With rigorous organisation, a well-monitored reconditioned instrument can be easily integrated into the ISO 17025 standard.
How a CNRS laboratory avoided 4 months of downtime and €91,000 in additional costs thanks to a reconditioned test device
A CNRS laboratory was able to keep its measurement chain operational by replacing an Agilent E4446A spectrum analyser that had broken down with a reconditioned model delivered in 48 hours.
5 tips to extend the lifespan of your reconditioned appliances
Refurbished equipment retains all its technical value if it is properly maintained. With a few simple preventive maintenance and metrological checks, it is possible to significantly extend its lifespan and guarantee its reliability.
Customer case: takeover of measurement equipment at Airbus
Taking back measurement equipment at Airbus involved inventorying, sorting and upgrading equipment accumulated over several programmes. Each piece of equipment was directed towards reuse, repair or responsible dismantling with Ateliers Sans Frontières, then documented in a complete traceability system.
