Frequency range 1 Hz ... 50 MHz
Five digits resolution (display for example x.xxxx kHz, x.xxxx MHz,
or xx.xxx MHz)
Measuring signal amplitude can be up to 30 v
4-40 m passive crystals can measure
Automatic range switching with different gate times
Optional addition or subtraction of a frequency offset ()
Very low component count: a PIC 16F628, 5 7-segment LED displays, a 20MHz crystal and a few resistors
Optional (configurable) power-saving which automatically turns
If the frequency does not change significantly within 15 seconds, the display turns off
Can use USB 5V or DC5-12V power supplyPackage Includes:1x DIY kit
