Advantest U3741 Spectrum Analyzer

Advantest U3741 Spectrum Analyzer

DESCRIPTION

The U3741/3751 portable spectrum analyzer supports a great range of applications, from use on production lines to system installation and maintenance. Its digital IF enables dramatic improvements in power measurement accuracy for digitally modulated signals. Moreover, the U3741/3751 provides twice the throughput of its predecessor. A light and compact 3 GHz/8 GHz spectrum analyzer, the U3741/3751 provides basic performance reliably and at a low cost.

•Better measuring speed due to high-speed processing (twice as fast as its predecessor) 

•Dramatically improved power measurement accuracy for digitally modulated signals 

•Built-in 3 GHz/8 GHz pre-amp standard •Average display noise level: -155 dBm/Hz@1 GHz, pre-amp ON 

•Tracking generator covering a frequency range of 100 kHz to 3 GHz/6 GHz 

•Lightweight and compact design, with a maximum weight of only 5.6 kg 

•Continuous operation of up to 2.5 hours with the battery pack

Compact Design with High Performance

5-minute warm-up time

With the U3741/3751, warm-up time has been reduced to a scant 5 minutes (at an ambient temperature of 20 to 30°C). This shortened period virtually eliminates pre-warming time as a consideration, and permits quick and accurate measurement.

High throughput

This spectrum analyzer delivers data transfer speed superior to that of its predecessor. While the previous model delivered 875 ms, the U3741/3751 boasts a speed of 350 ms: double the system throughput *2 (using the GPIB interface)*3. This faster speed contributes to a significant reductions to cost of test on production lines and in similar applications.

Improvements in overall accuracy

Digitized IF sections and innovative circuit technology dramatically improve absolute power measurement accuracy. ±0.8 dB (10 MHz to 3 GHz: U3741/3751) ±1.0 dB (3 to 8 GHz: U3751)

Standard USB (1.1) interface

Screenshots in BMP or PNG format can easily be sent via USB external memory. Users can easily store data, and easily paste measurement data into repor.

Up to 2.5 hours *1 of nonstop battery-driven operation

The spectrum analyzer uses one of three power systems: AC (100 V/200 V), DC (+11 V to +17 V), or the battery pack. This flexibility enables measurement in a variety of applications, whether in the factory or in the field.

Compact design

At about half the size of its predecessor, this spectrum analyzer offers a compact design while maintaining the same level of functionality. Its form factor gives it portability, enabling it to be used anywhere.

Extensive array of measurement functions

Measurement functions include Channel Power, Total Power, Avg Power, OBW, ACP, Spurious measurement, Harmonics measurement, IM measurement, Noise/Hz calculation functions, multi-marker (10 markers), delta marker, peak marker functions, a channel setting function, and a 3-trace simultaneous sampling function.
