Digital Wattmeter
The extra input B is for a later SWR brigde project, also the TX serial output will be in use later.
The uncalibrated signal response is: +1/-1 dB from 1MHz to 450MHz.
Input SWR vill varry from 1.00 to 1.30, depending on input frequency.
To make the SWR this good, you need to assemble the input circuit correct and adjust the capasitor.
Input power range: -60 to +30dBm that is 1 nW to 1 Watt.

Build your own 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 "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
