Bench Spectrum Analysers
A bench spectrum analyser is a crucial instrument used by technicians and engineers to examine the composition of electrical signals. Unlike an oscilloscope, which plots a signal’s change over time, the analyser displays the signal’s power or amplitude against its frequency across a selected range. These large, AC-powered benchtop units are specifically designed for high-performance and high-accuracy measurements in fixed settings, such as a laboratory or production facility. They provide the detailed frequency domain analysis essential for developing and verifying modern electronic systems, particularly those involving radio frequency (RF) communications.
Applications
- Wireless Communication: Testing signal power, occupied bandwidth, and modulation quality for systems such as Wi-Fi, 5G, and satellite communications.
- Interference Detection: Quickly identifying and locating unwanted signals, noise, or spurious emissions that degrade system performance.
- EMC Pre-Compliance: Debugging and testing a device’s electromagnetic emissions to ensure it meets strict regulatory standards before formal compliance testing.
- RF Component Testing: Characterising the performance, gain, and distortion of passive and active RF components like filters, amplifiers, and mixers.
- Manufacturing and Quality Control: Verifying the spectral integrity of products during production to maintain consistent quality and performance.
