Abstract
A testing device includes an oscillator circuit with an inline device. The oscillator circuit includes a loop having a variable gain amplifier and a variable feedback block. The inline device is installed between the variable gain amplifier and the variable feedback block. An output of the variable feedback block is input to the variable gain amplifier. A processor varies a phase of the variable feedback block to locate a block phase shift of the variable feedback block at which the oscillator circuit generates an output signal, determines a device phase shift of the inline device from the block phase shift, and adjusts an operation of a driven circuit operating off of the output of the oscillator circuit using the device phase shift of the inline device.
