    S Meters - (13 companies)
    ...a receiver 's detector stage is applied to an ammeter. If the receiver has an automatic gain control (AGC) amplifier, this stage can be used to drive the S meter and control the gain of the receiver. S meters are calibrated in terms of S units up... Search by Specification | Learn More
  • Milliohm Meters-Image
    Milliohm Meters - (75 companies)
    Milliohm meters are capable of measuring very small resistances. Devices which use a four-wire Kelvin probe system pass a test current through the probe so that the voltage is sensed by the center pin. This test method eliminates contact resistance... Search by Specification | Learn More

Conduct Research 1µV per meter. dBJ. Energy relative to 1 joule. Used for spectral densities where 1 Joule = 1 W/Hz. Examples. If the numerical value of the reference is undefined then the decibel may be used as a simple measure of relative amplitudes. As an example, assume there are two loudspeakers, one emitting...

/m)-120]/20}. As above, simply plug away. dBW/m2 = 10Log10[V/m - A/m]. A simple relation to calculate decibel-Watts per square meter. dBmW/m2 = dBW/m2 + 30. The derivation for the constant in the above equation comes from the decibel equivalent of the factor of 1000 used to convert W to mW and vice...
