A spectrum analyzer is a test instrument that displays how the power of a signal is distributed across frequency. it is equipped with a HD screen to display frequency details, making it clear at a glance the on-site interference frequencies. Designed by the RF experts at Rohde & Schwarz, all spectrum analyzers feature exceptional signal. These two methods of representation are linked together via the Fourier transform, which means that there is a characteristic frequency spectrum for every signal that can be represented in the time domain. From detecting hidden sources of noise to verifying device performance against industry standards, this instrument is one of the most versatile tools in an engineer's lab. These instruments are used by hobbyists, academics and professionals alike.
