This is an eight digit frequency counter with a frequency range of either 40MHz to 520MHz (Input A), or 10Hz to 60MHz (Input B). Do not use both inputs at the same time.
The maximum signal on Input A, which has an input impedance of 50 ohms, is 5V / 27dBm. Exceeding this will destroy the frequency counter. Input B is more tolerant, with an input impedance of 1Mohm and and 25pF loading (making it suitable for oscilloscope probes).
