Sequence component tester

A digitally controlled two legged bridge comprising a component under test and a reference resistor selected from a decade ladder as a function of the exponent of the value of the component under test. A drive signal, whose amplitude is a function of the significant digits of the value of the component under test, and a reference signal are connected to selected points on the bridge in the appropriate waveform as a function of the component under test. The output of the bridge is fed back to the drive signal to balance the bridge and is compared with acceptable percentage error levels, for the component under test.
