AN301: LCR Meter Measurement Accuracy

... LCR meters make taking L, C and R measurements very easy. One can simply hook up the test component between the clip terminals and get the reading on the display with very little effort. However, if you want to be certain of the measurement that you have made, you must understand how an LCR meter op ...

... VOUT can be adjusted by cutting open the trace across resistor R2 and installing feedback resistors R1 and R2. The equation to adjust the output voltage is the following: VOUT = VSET(1 + (R1/R2)) where VSET = 1.23V Resistor R2 must be 50kΩ or less to maintain stability, accuracy, and high-frequency ...

... The FMS6203 outputs are DC offset from the input by 150mV; therefore, VOUT = 2•VIN DC+150mV. This offset is required to obtain optimal performance from the output driver and is held at the minimum value to decrease the standing DC current into the load. Since the FMS6203 has a 2x (6dB) gain, the out ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
