Informatie
The MS610A Spectrum Analyzer has a wide frequency range of 10 kHz to 2 GHz, and covers a broad range from the video band to the UHF/VHF band. It is used mainly for spurious response measurement of radio equipment, etc., assembly line adjustment, distortion measurement of various performance elements and circuits (for example, in amplifiers), and broadcast signal panoramic reception and EMI (Electro Magnetic Interference) measurements, etc. The MS610A has multiple functions for these uses: a coupling function, measured level digital display function for efficient measurement, a GP-IB function, which allows simple automation of measurement, and an EMI measurement function with QP (Quasi Peak) detector. The last two are available as options. A tracking Generator (MH680A) is available as a peripheral device for transmission measurement.
