Spectrum analysers are measuring instruments for detailed monitoring of radio-frequency signals: from locating interference and spurious emissions to tuning antennas, filters, amplifiers and transmitters. They display a signal’s power distribution across frequency, helping you quickly spot “notches”, harmonics, intermodulation products and front-end overload.
This category includes solutions for the laboratory, service centres and field work. Models are available with different frequency ranges, noise floors, dynamic range and bandwidth. For accurate measurements, pay attention to RBW/VBW, phase noise, sensitivity, maximum safe input level, and whether a preamplifier and attenuator are built in. For fast analysis of wideband signals, Real-Time functions, a spectrogram and short-pulse capture modes are especially useful.
Many analysers support measurements with markers, channel power, ACPR, occupied bandwidth (OBW), EMI pre-compliance, as well as trace and report saving. Modern interfaces (USB/LAN), remote control (SCPI) and PC software make automation easier, while a large display and fast screen refresh keep work comfortable.
Need an instrument for a specific task — tuning a radio link, testing modems, Wi‑Fi/ISM devices or telecom equipment? We’ll help you choose the optimal specifications for your budget and use case.
