Advantest U3661 Spectrum Analyzer

Advantest U3661  Spectrum Analyzer

INTRODUCTION

The radio communication field is undergoing fast growth on a global scale, expanding the frequency band usage across the spectrum from the microwave to the millimeter-wave bands. The U3661, at 8.5 kg, is the lightest weight microwave spectrum analyzer in the world.* It accommodates the diverse needs of these various communication systems. 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, lightweight design of the U3661 utilizes a three-way power source system which includes battery; it is an optimum analyzer for field measurement. This unit also has a built-in RC232 interface for a personal computer, facilitating flexible data management using standard memory cards.

Full Range of Features for Portability and Application Support

8.5 kg or less, lightest in its class

The U3661 is light and compact (8.5 kg or less without the battery pack or 10.8 kg or less with the pack). The easyto-attach strap allows the analyzer to be worn on the shoulder and easily carried. The U3661 is rugged enough to satisfy the requirements of vibration, shock and drop tests, allowing them to be used safely under harsh field conditions.

Battery Provides 1 Hours of Operation. Three Power Sources to Choose From

The U3661 operates not only on 100/200 V AC power but also on +10 to +16 V DC power or the Battery Pack. The Battery Pack allows 1 hour continuous operation at a full charge, making it easier to perform logistically wide-ranging measurements such as maintenance and installation work. Rapid two- hour battery charging time.

Large Color TFT LC Display

The U3661 employ a 6 inch color TFT LCD display and a tilt mechanism that allows a angle of ±15 degrees, remarkably improving the visibility and efficiency of analysis work.

2 -Slots Memory Card Drive

Having two memory card drives conforming to JEIDA-Ver. 4.1/PCMCIA Rel. 2.0 as standard, measurement condition setup, and data recording can be performed while two memory cards are loaded in the drives. There are three different record formats for memory card: binary, bit map, and text (CSV). In particular, the text (CSV) format is handy for data analysis and report creation using spreadsheet software on a personal computer.

Wide Array of Analysis Functions

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.

Selectable Data Save Format

SAVE in Binary Format

All measurement conditions and waveform data are stored on the memory card. The stored data can be reproduced on the U3661. Multiple measurement conditions can be saved, and can be recalled at any time, thus, complicated operations may be repeated automatically by simplified recall from memory. The saved measurement conditions can also be utilized to manage a large amount of waveform data.

COPY in BITMAP Format

Basically, this function outputs a screen image directly to the printer or plotter. However, when the memory card is specified for the copy target, the graphic image data from the screen is saved on the memory card in BITMAP format. This data file can also be opened on a PC for managing screen image files.
