Portable Spectrum Analyzer TW4950

 

Product Overview :

 

Techwin Portable Microwave Spectrum Analy zer TW4950 is the new generation portable microwave spectrum analyzer developed by Techwin using broadband microwave component integration design technology, microwave multilayer PCB design technology, efficient voltage transformation system design technology and mu lti-band sweep & individual thread processing technology. Compared with the last generation pr oduct, its frequency range increases by 5 times, display average noise level decreases by 20dB, si ngle sideband phase noise decreases by 20dB and measuring speed increases by 4 times, featured by broad frequency band, high performance index, small size, light weight, flexible power supply and easy maneuvering, suitable for field service.
Available in the frequency range 1MHz ~ 18 GHz, Techwin Portable Microwave Spectrum Analyzer TW4950 can meet the ne ed of measurement from short-wave through to wave band Ku. It uses menu-type operation in terfaces and graphical display of measurement result, which operation is simple and result is direct viewin g. Portable microwave spectrum analyzer is internally built with a large-capacity FLASH memory and supports USB external memory by which the field measurement curves can be stored for subsequent analysis and processing and filing up for management.
Techwin Portable Microwave Spectrum Analyzer TW4950 is mainly used in the development, repair and maintenance etc. various sectors of radar and communication equipment as well as by the spectrum monitoring and management department for spectrum monitoring and management.

High measurement speed

The minimum sweep time is only 600ms at 18GHz span.

Abundant measurement functions

In addition to spectrum measurement function, it also has the functions of occupied bandwidth measurement, channel power measurement, adjacent channel power measurement, etc

Field intensity measurement function

The field intensity measurement function can position the interference signal by measuring its field intensity; and allows users to edit the antenna factor.

Support both linear sweep and list sweep

The list sweep mode can help users easily realize fast measurement of sub-band

Chinese/English Menu for easy use

This instrument is available in menus in Chinese and English versions, the switching between which can be realized by one button conveniently.

Built-in large-capacity memory and USB external memory extension supported

Techwin Portable Microwave Spectrum Analyzer TW49 50 is internally built with a large-capacity memory and supports USB external memory extens ion, which can meet the requirements of trace storage in field measurement.
