Information
The MS610 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 MS610 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.
