Promax FD-252

The FD-252 digital frequency counter is designed for application that require a high frequency range. For that purpose the instrument is equipped, in addition to the 20 Hz-160 MHz input, a second input for measurement up to 2.4 GHz with an impedance of 50 Ohms.

FD-252 has an excellent frequency sensitivity and three selectable gate time fixed values: 2 sec., 0.2 sec., and 20 msec., thus enabling the user to obtain an optimum ratio between the measurement time and the resolution. In addition, it has a selectable band-pass filter at input A. In this way it is possible to measure low-frequency signals, removing interferences in the measure. Also equipped with an 8 digit L.E.D. display which facilitates frequency reading.
