  • Patent number: 11125815
    Abstract: A reconfigurable optic probe is used to measure signals from a device under test. The reconfigurable optic probe is positioned at a target probe location within a cell of the device under test. The cell including a target net to be measured and non-target nets. A test pattern is applied to the cell and a laser probe (LP) waveform is obtained in response. A target net waveform is extracted from the LP waveform by: i) configuring the reconfigurable optic probe to produce a ring-shaped beam having a relatively low-intensity region central to the ring-shaped beam; (ii) re-applying the test pattern to the cell at the target probe location with the relatively low-intensity region applied to the target net and obtaining a cross-talk LP waveform in response; (iii) normalizing the cross-talk LP waveform; and (iv) determining a target net waveform by subtracting the normalized cross-talk LP waveform from the LP waveform.
