RF Measurement has been an expensive work so far the cost of measuring RF Power Meter instruments are concerned. RF Power Meter is based on PIC16F876 microcontroller, AD8307 and 2x20 LCD display. Full documentation is included.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
