Input-referred calculations are a valuable tool to understand the expected performance of a measurement system, helping to optimize designs and inform system specifications. Why input-referred ...

Two very desirable features for a precision measurement system based on an analog-to-digital converter (ADC) are high input impedance and a wide input range, ideally including or extending slightly ...

A directional coupler is used to sample a small amount of input signal power for measurement purposes. Port 1 is the input port; port 2 is the output port; port 3 is the coupled port; port 4 is the ...
