A resistance is a DC resistance, which can be measured with an ohmmeter. If there is a capacitor in the signal path we measure nothing. With a voice coil of a speaker we can measure a DC resistance. With a digital multimeter DMM resistances can be measured easily, but we cannot measure...
The LED’s forward voltage must be measured with submillivolt accuracy after the high-current pulse, which is difficult when the overall circuit voltage can approach 200 V. The 34411A digital multimeter from Agilent Technologies Inc. of Santa Clara, Calif., was used because it is a high-spee...
To verify input-referred noise, short the input of the amplifier to ground and measure the noise at the output. Measurements are taken directly with an RMS voltmeter or oscilloscope; noise spectral density is viewed with a spectrum analyzer. Measured noise spectral density of the wideband output ...
Let's find the current too, from P = I2x R I(rms) = sqrt(5/50) = 0.316 amps(rms). As a check, the voltage divided by the current should be equal to the 50 ohm load resistor, i.e.: 15.8/0.316 = 50 The AC waveforms at the dummy load are sinewaves. Since our multimeter ca...
(likely a switching regulator inside the oscilloscope) that was larger in amplitude than the input referred noise. Placing it close to a benchtop multimeter resulted in a large 60Hz signal. Figure 6 shows just how sensitive the amplifier is when placed just a few inches in front of the ...
(e.g., pico-amps) such that the I-R drop is low, and the voltage seen by the sense terminals is the same as the voltage developed across the resistivity contacts. This enables a total resistance Rxof the electrical path between the resistivity contacts to be quantified. The resistance Rx...

The load consumes a current of 5 amps. The battery completely discharges to 25.52 V in a period of 1 h. A 1 C or 1000 mA rate means this particular discharge current will fully discharge the battery in 1 h; likewise, a standard charge on a datasheet was defined as 0.5 C or 500 ...
