Fast-Installations-Tester FIT
SCHOMANDL offers different FIT models depending on the
application and required frequency range. The FIT 400 is our best priced model and covers 400 MHz to 1000 MHz.
This frequency band allows to check most of the international analog and cellular mobile
networks such as GSM 900, AMPS, D-AMPS, TACS, NMT 450/900.
The FIT 70 covers the same public mobile networks but
already starts at 70 MHz. The lower frequency band is used for private mobile radio -
PMR, at
police and fire departments, taxis, customs etc. The FIT 1700 is designed to check mobile
radios from 1700 MHz to 2000 MHz in GSM/DCS/PCS -1800/1900 networks. The separate
RF-head is inserted without long interconnection cables between the transmitter output of the
mobile radio and the antenna cable, thus avoiding additional measuring errors. Now just
read-off the forward & reverse RF power in Watt or dBm and the VSWR from the
high-contrast LCD.
These are useful parameters to determine the quality of the systems
components and the workmanship of the installation. The FIT Series identify automatically
whether a continuous analog RF signal or bursts from a cellular system are applied. The
storage of max. and min. values permits the detection of intermittent faults, for example during
engine start. In case of a short-circuit in the antenna or in the antenna cable, a red LED on the
RF-head gives a warning.
