A high test speed spectrum analyzer with 3.25 GHz, provides the fastest 204 μs sweep speed. Users, via high speed sweep time, can easily handle and analyze modulation signals. The keys to handling modulated signals are fast sweep time and signal demodulation functions. In addition to the analog AM/FM demodulation and analysis function, also provides digital signal ASK/FSK, and 2FSK demodulation and analysis capabilities. Nowadays, EMC issues are very crucial to product’s design processes. Therefore, has incorporated the EMC pretest solution to facilitate EMC tests. The simple and easy EMC pretest procedures from Spectrum Analyzer can tremendously shorten users’ product launch timeline.
