Product description
Professional Oscillator Tester Kit 1Hz-70MHz Oscillator DIY Kit Frequency Counter Kit Compact-size LED Display Durable-
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 for 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.
Frequency Range: 1Hz-75MHz
50MHz Input Impedance: 1.1M, Parallel with about 10PF
Current Consumption: 50mA with 7 to 9V Input Jack
Display: Digital LED Display
PCB Size: 80x58mm/3.15x2.28"
