The FIT series belongs to the portable, inexpensive measuring devices intended for fast check digital (including cellular) and analog systems of a radio communication. These testers are used both at operational tests of various equipment, and in various sales outlets, for example for check and fast diagnostics of mobile phones before their return to the service center. Such approach allows to reduce an idle time, reduces expenses, and guarantees return to the manufacturer only of faulty devices. Thus, in addition, the FIT series allows to keep image of this point of retail trade. Work with testers of the FIT series is so simple that after several minutes practically everyone will be able to work with the device. The SCHOMANDL company offers various models of the FIT series, depending on problems of application, and also the chosen frequency range. Frequency ranges with which FIT series testers work cover the majority of the famous standards of analog and cellular systems of a radio communication, including GSM 900, GSM/DCS 1800, AMPS, D-AMPS, TACS, NMT 450/900.
