The RF installation tester FIT 400 measures the power output by the transmitters and the power reflected by the antenna installation. The indication can be in either Watt or dBm. It is also possible to indicate VSWR instead of reflected power.
The FIT 400 includes a digital voltmeter with a conversion time that is so short that even dips in the supply voltage during the transmitted pulses can be detected. The maximum and minimum values that occur during the measurement are saved.
