Features:

Frequency range: 1Hz-75MHz (in fact, it can work up to 78MHz).

Four-digit or five-digit display resolution (for example, x.KHz xxx, x.xxx.MHz, or xx.xxMHz).

Automatic switching range with different gate times.

addition or subtraction of programmable frequency offset.

Input impedance: 1.1 M, parallel to about 10pF.

Input sensitivity: Typically less than 20mV RMS from 1Hz-100KHz, rising to 35mV at 20MHz and 75mV at 50MHz (150mV at 78MHz).

Current consumption: 50mA with 7 to 9 V input.

Optional (configurable) power-saving mode that automatically shuts off the display if the frequency does not change significantly within 15 s.
