Spectrum Analyzers and Signal Analyzers

We provide a full range of instruments, including powerful Benchtop Signal Analyzers for deep analysis of complex modulated signals and rugged Handheld Spectrum Analyzers for field troubleshooting and interference hunting. Use them to measure key characteristics like occupied bandwidth, adjacent channel power (ACP), spurious emissions, and phase noise. We also offer specialized Noise Figure Solutions to accurately quantify the noise performance of amplifiers and receivers, which is crucial for maximizing system sensitivity in RF/microwave design.

The Spectrum Analyzer is a frequency-domain powerhouse, allowing engineers to visualize the spectral content of a signal. This is fundamental for identifying sources of interference, measuring transmitter output, and ensuring regulatory compliance.

A modern Signal Analyzer goes beyond basic spectrum measurement to offer advanced digital demodulation capabilities, essential for analyzing complex schemes like QAM or OFDM used in Wi-Fi and 5G.

Our handheld spectrum analyzers are perfect for site surveys, tower maintenance, and PIM (Passive Intermodulation) testing. Integrating a dedicated noise figure meter allows designers to optimize the noise performance of the entire receiver chain for maximum sensitivity.
