A section processing apparatus has a mark forming control portion that transmits control information for forming marks on a surface of a sample. Each of the marks has at least two portions intersecting at a converging portion located at a previously determined position of an observation target section of the sample or in the vicinity of the previously determined position. A first focused ion beam apparatus emits a first focused beam for forming each of the marks on the surface of the sample based on the control information transmitted by the mark forming control portion and for processing a section of the sample. The section of the sample is processed by scanning the first focused beam in parallel with the at least two portions of the marks in the direction of the converging portion, while the section of the sample and positions of the marks are observed by a second focused ion beam apparatus, and to finish processing of the section of the sample when the first focused beam reaches the converging portion or a vicinity thereof.

A probe interface circuit and a probe adaptation circuit for a probe of an oscilloscope, wherein the probe includes a probe interface circuit and a probe front-end circuit, the probe interface circuit includes a control circuit, a detection circuit and a coaxial transmission circuit; The communication interface of the oscilloscope receives the control signal generated by the oscilloscope, and configures the DC offset according to the control signal to generate the offset configuration signal, and outputs the offset configuration signal to the probe front-end circuit through its output terminal, so that the probe front-end circuit is in the Under the action of the bias configuration signal, the DC bias is superimposed on the signal to be detected, and the coaxial signal with the output impedance matching the BNC interface of the oscilloscope is generated through attenuation adjustment and impedance adjustment. Since the probe interface circuit can generate the offset configuration signal according to the control signal, it is beneficial to realize the free superposition of the DC offset of the signal to be detected, and overcome the functional deficiencies of the existing oscilloscope probe.
