RF Milliwatt Meters
Type NDB-2 and NDB-3
-
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

Potential Meters

Potential meters are basically electrometers which have extremely high input resistances in order to keep the feeding reference electrode free of load. This is necessary to maintain the true potential. pH - meters can be used as potential meters when fast reading is not required, because common pH meters are very slow. When the potential answer to current pulses is to be followed, potential meters are essential.
