Measurement arrangement having a calibration substrate and electronic circuit

摘要

A calibration substrate having at least one calibration standard with at least two electrical connection points, each for one measurement gate of a vector network analyzer. At least one electrical connection point is formed of at least one calibration standard having a switch, wherein the switch has a first electrical contact electrically connected to an electrical connection point of the calibration standard, a second electrical contact designed for electrically connecting to a measurement gate of the vector network analyzer, and a third electrical contact, wherein the switch is designed such that an electrical contact is established either between the first and third electrical contact or between the first and second electrical contact.

主权项

1. A calibration substrate having at least one calibration standard comprising at least two electrical connection points, each for one measurement port of a vector network analyzer,
at least one of said at least two electrical connection points of said at least one calibration standard including a switch, wherein the switch comprises: one first electrical contact which is electrically connected to an electrical connection point of the calibration standard; a second electrical contact which is configured for electrically connecting to a measurement port of the vector network analyzer; and a third electrical contact, wherein the switch is configured such that with the second electrical contact free and electrically connected to nothing, the switch makes an electrical connection between the first and third electrical contacts;wherein an electrical connection between the second and first electrical contacts and between the second and third electrical contacts is broken, and that with the second electrical contact electrically connected to said measurement port of the vector network analyzer, the switch breaks the electrical connection between the third and first electrical contacts and makes an electrical connection between the first and second electrical contacts, wherein an electrical connection between the third electrical contact and the second electrical contact is broken.
