TFC-3000U (Universal Frequency Counter) là máy đếm tần số 1Hz - 3000MHz của Lodestar. Hiển thị 8 số. 3 kênh ngõ vào
TFC-3000U is a digital universal frequency counter which can measure input frequency from 1Hz to 3,000MHz. As high speed processor built in, it can have a detailed resolution to 100μ Hertz when frequency is above 1Hz input. High stable TCXO is inserted in TFC-3000U, so accurate frequency measurement can to obtained even units work for a long period. Additional function includes pulse totalizing, input signal period measuring are also built in unit.
