Abstract
An impedance standard substrate for calibrating a vector network analyzer comprises a first surface and a second surface opposite to the first surface. A thru-circuit has two contacts electrically connected to each other. The two contacts are disposed on the first surface and the second surface, respectively. The impedance standard substrate further comprises a pair of open-circuits, a pair of short-circuits, and a pair of load-circuits disposed on the first surface and the second surface, respectively.

An impedance standard substrate for calibrating a vector network analyzer comprising:
- a first surface;
- a second surface opposite to the first surface;
- and
- a thru-circuit having two contacts electrically connected to each other and respectively disposed on the first surface and the second surface.
A method for calibrating a vector network analyzer, which generates a measuring signal and comprises two probes for transmitting the measuring signal, comprising the steps of:
- providing an impedance standard substrate which has a first surface and a second surface opposite to the first surface;
- providing a thru-circuit having two contacts electrically connected to each other and respectively disposed on the first surface and the second surface;
- and
- driving the two probes to be in contact with the two contacts, respectively, and sending the measuring signal.
An impedance standard substrate for calibrating a vector network analyzer comprising:
- a copper core defining a first surface and a second surface;
