High impedance alternating current sensing transformer device between two bolometers for measuring insertion loss of test component
An improved test method accurately measures the insertion loss of RF components while avoiding amplifier drift. Currents are balanced across a bridge transformer with shorted probes and then with each component to be tested. Differences in adjustments indicate the loss.
