Multi-screen display

?

For testing digital mobile communication equipmentHigh-speed time domain sweep (Option 04) The Trace A and Trace B waveforms are superimposed on the same screen, and two spectra with different frequencies are displayed si- multaneously. In addition, it is possible to simultaneously display spectrum and time domain screens for the same signal. The multi- screen display permits efficient signal level adjustment and harmon- ic distortion measurement. In addition to being able to display amplitude in the time domain, it is possible to display the FM demodulation waveform. Testing of TDMA-type radio equipment requires time domain (zero- span) measurements of antenna power, transient response charac- teristics of burst transmissions, transmission timing, and other char- acteristics. The high-speed time domain sweep option boosts sweep time to 12.5 µs and resolution to 0.025 µs. This option must be used with the trigger/gate circuit (Option 06).
