Advantest R3681-72-73 Spectrum Analyzer with Modulation Analyzer and Generator

At 8.5 kg, the U3661 is the world's lightest microwave spectrum analyzer, 

meeting the diverse needs of a wide range of communication systems.

The U3661 not only enhances the basic performance of a spectrum analyzer, 

but also includes many standard features such as power calculation and high-speed scanning.

The U3661's compact, lightweight design and three-way power supply system, 

including batteries, make it the perfect analyzer for field measurements.

The unit also has a built-in RC232 interface for connection to a personal computer,

facilitating flexible data management using standard memory cards.

Excellent basic performance and measurement applications

Adjacent Channel Leakage Power

The U3661 obtains the total power from the measurement data on the screen.

It then integrates the power over the specified bandwidth (BS) to obtain its ratio to the total power.

ACP POINT and ACP GRAPH measurement methods can be selected.

Various Measurement Applications Power Measurement Functions

Average power

Digital mobile communication systems use modulation patterns that can handle signals with large amplitude variations.

Therefore, we have included an average power calculation function that allows power measurement of signals with amplitude variations.

Total Power

For spread spectrum signals used in CDMA or wireless LANs, the total power measurement function is essential. 

This function consists of two modes: a channel mode for measuring the in-band power specified in the measurement window,

and a total power mode for measuring the total power over the entire measurement span.

Wideband scanning

The U3661 can continuously scan a frequency bandwidth from 9 kHz to 26.5 GHz on a single screen. 

Harmonic measurements or spurious signal measurements over a wide bandwidth can be easily compared relative to the fundamental.

Outstanding signal purity

The U3661's local oscillator is equipped with a precision synthesizer that achieves a signal purity 

of -100 dBc/Hz (at frequencies ≤3.2 GHz and an offset frequency of 10 kHz). 

It meets a variety of needs, from adjacent channel leakage power measurements at radio facilities to microwave equipment evaluation.

Occupied frequency bandwidth

The U3661 calculates the bandwidth for a specified power ratio based on the measured spectrum

data and then displays it with a marker. In addition, it displays the occupied frequency bandwidth (OBW) and carrier frequency (FC).
