Spectrum Analysis Mode

While entering the spectrum mode, the MDO-2000E series will display a full screen of the frequency domain. Users can input Center frequency, Span, Start frequency, and Stop frequency based on test requirements so as to rapidly and intuitively observe the required frequency range that allows users to experience the user interface of a real spectrum analyzer. While observing frequency domain display, engineers can observe waveform characteristics that are not easy to be seen from time domain waveforms, for instance, the harmonic composition of a waveform and the frequency characteristics of a modulation signal. Compared with oscilloscope FFT, the MDO-2000E series allows engineers to effectively conduct signal measurements on the frequency domain.

MDO-2000E series frequency domain also includes Spectrum Trace Type settings (Normal, Max-hold, Min-hold, and Average). Users can freely select various Spectrum Traces for simultaneous display. The detection method (Sample, +Peak, -Peak, and Average) can be individually set for each Trace. Additionally, users, via Cursor, can manually mark the corresponding positions to reflect Frequency and Amplitude. The Search function can also be applied to the log spectrum's Peak Table. Amplitude is displayed with dB, and the Marker can obtain measurement data. Users can use the Search function to search and mark the amplitude and frequency of the spectrum signal. Search methods include Max. peak and threshold. Measurement results can be displayed and saved.
