The Anritsu MF1603A is a precision frequency counter engineered for measurements from 0.1 MHz to 3 GHz across telecommunications, electronics design, and RF testing environments. It delivers fast acquisition and 1 Hz measurement resolution through reciprocal and vernier techniques, enabling 10-digit display in 1 second. The instrument measures frequency, period, pulse width, and totalizing functions with selectable gate times from 0.01 s to 10 s. Its 10 mVrms sensitivity and 50-ohm input impedance accommodate signals up to 5 Vrms maximum.
