A frequency response analyzer ('FRA') is often used to measure gain and phase plots of control loops (Bode plots), filter responses and general frequency domain transfer functions. The FRA generally ...
The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...
Time-domain reflectometry (TDR) is a technique that measures and displays the impedance of a network (cable, filter, and so on) over time. Traditionally, this is done with a device that generates very ...
Some 30 years ago, my complement of RF test equipment consisted of a General Radio 1606B impedance bridge (GR bridge), a Potomac SD31 synthesizer-detector and a Delta OIB-1 operating impedance bridge.
One-Sided Measurement of Power Supply Impedance Without Connectors presents an approach for measurement of PDN impedances in PCBs that uses small contact pads on one side of the PCB, which are ...
