U3641N – Advantest Spectrum Analyzers
3.00GHz (High end frequency limit)
The U3641/3641N is a 3-GHz synthesized spectrum analyzer ideal for field use. With a lightweight, compact size and threeway power supply including battery operation, the U3641/3641N has been designed specifically for field installation and maintenance applications. In addition, with the inclusion of a synthesized local oscillator, the U3641/3641N allows highprecision and high-stability measurements with a minimum resolution bandwidth of 100 Hz.
A fast zero span sweep speed of 50 µs allows characterization of burst signal rising and falling edges and the measurement of power during on and off periods.
The U3641/3641N are portable analyzers which can be used for maintenance on various aspects of CATV and PHS/PDC.
