Tīmeklis2024. gada 16. maijs · For raw RF leve measurement (low accuracy) a diode probe for the analog meter (Sencore FetVM) does just fine. Helps if you have a weak signal source for RX and a good RF power meter/dummy load. Allison-----Please reply on list, No direct email please. it goes to bit bucket due address harvesting in groups.IO TīmeklisThis is the Radio Shack® 22-216 autoranging multimeter. This is a very strange multimeter. Autoranging is not a feature commonly found on analog deflecting meters. As this meter is powered, it also uses op amps to amplify the signal. With the op amps, the actual impedance of the meter is not visible to the user - the user sees a FETVM …
