The Anritsu MS710C Spectrum Analyser is a wide band, very sensitive receiver.
The MS710C works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities.
The received frequency spectrum is slowly swept through a range of pre selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the this unit.
The MS710C has been designed as a high-performance microwave spectrum analyser with wide user applications.
The MS710C is easy-to-use and has a variety of functions suited to user's requirements.
Use of a simplified PLL synthesizer local oscillator gives a high accuracy of 30 kHz/6.5 GHz (MS710C) and a high resolution of 100 Hz/6 dB (=70 dB/3 dB).
