Spectrum analyzer

Spectrum analyzer
Product Detailed

Combined with the near field probes of Mz530, it can detect the missing fields of radio frequency.


SM5011 is equipped with a tracing signal generator, and in the combined use of spectrum analyzer/tracing signal generator, it can complete the work which cannot be done by other frequency sweep system, such as sweep generator/network analyzer, sweep generator/spectrum analyzer, and sweep generator/oscilloscope, etc.
