Advantest U3661
Advantest U3661 Spectrum Analyzer
Description
The Advantest U3661 is a microwave spectrum analyzer which accommodates the diverse needs of various communication systems.
U3361 is the lightest weight microwave spectrum analyzer in the world (April 1998).
As well as enhanced basic performance as a spectrum analyzer, the U3661 is equipped with many standard functions such as power calculation and high-speed sweep.
The compact U3661 uses a three way power source system which includes battery; it is an optimum analyzer for field measurement.
U3661 has a built-in RC232 interface for a personal computer and also provides data saving in various formats such as Binary and CSV; COPY in BITMAP format.
The U3661 has a 6-inch color TFT LCD display and a tilt mechanism that allows an angle of ±15 degrees.
A battery pack can be used for 1 hour continuous operation at a full charge. Several Power measurement functions are available with U3661 which helps in varied measurement applications.
Along with basic functions such as a frequency counter with a 1 Hz resolution and a 20 dB gain preamplifier, the U3661 comes standardly equipped with analysis functions for measuring items such as dB down, third order intermodulation distortion, AM modulation, occupied bandwidth, and adjacent channel leakage power.
GO-NO GO evaluations of the displayed waveform can also be easily performed using the limit line and PASS/FAIL functions which allow upper and lower limits to be set on the screen.
The U3661 calculates the bandwidth for the specified power ratio from measured spectrum data and then displays it with the marker. In addition, it displays the occupied frequency bandwidth (OBW) and carrier frequency (FC)
