FREQUENCY METER - FMETER - PROGRAMMED SYSTEM

Retired

Description

Meter, frequency counter or fmeter - all these names define the device used to measure the frequency. This is undoubtedly one of the basic instruments in the electronics studio. Models with high measuring accuracy are equipped with eight- and ten-digit reading fields. Meanwhile, a meter that has three or four significant digits is often enough. Then, the entire device may have smaller dimensions, which allows it to be easily incorporated into portable equipment. This is the set presented. The meter was built using PIC 16F628. Its structure includes all the functional blocks necessary to measure the frequency. The appropriate program and several additional elements in the SMD technique make the whole system extremely small. Practically, printed circuit boards are added to the display - they are much smaller from it.

The device is particularly recommended for portable devices, where frequency measurement is required

Selected parameters:

  • Frequency measurement in the range of 500kHz - 20MHz
  • Reading on a four-digit LED display
  • Possibility of lowering the lower measuring limit to approx. 10Hz and upper to approx. 50MHz
  • It is possible to program the added (subtracted) intermediate frequency
  • Power supply - 9-12Vdc
  • Tile dimensions:
    • 25 x 38mm
    • 25 x 23mm
  • Programmed layout
