4 Applications in test and measurement

Supporting multiple frequency bands is essential for test and measurement equipment given the diverse and evolving needs of various applications. Wideband test equipment’s ability to operate across multiple frequency ranges makes it a versatile tool for comprehensive testing across different systems and technologies. As technology advances and new frequency bands are introduced, the need for equipment that can quickly adapt and switch between multiple bands becomes increasingly important.

In spectrum analyzers, fast-frequency-hopping techniques enable fast and accurate measurements by reducing sweep times and improving the ability to detect transient signals. The rapid switching capabilities of advanced ADCs with multiple NCOs or fast reconfiguration methods such as FRI enable more efficient analysis across broad frequency ranges, enhancing the overall performance and utility of spectrum analyzers in both research and field applications.

For wireless testers, fast-frequency-hopping techniques play a crucial role in characterizing and troubleshooting communication systems. By enabling rapid transitions between frequencies, these techniques improve signal fidelity and reduce testing cycles. This capability is particularly valuable in assessing the performance of wireless devices under multiple frequency conditions.

Beyond spectrum analyzers and wireless testers, fast-frequency-hopping techniques offer significant benefits in many other test and measurement applications. General-purpose signal analyzers and RF signal generators, for example, can leverage these techniques to provide more flexible and accurate testing across multiple frequency bands. Multiband receivers also benefit from the ability to quickly switch between bands, ensuring reliable performance in dynamic testing environments.
