Abstract
An apparatus for measuring s-parameters using as few as one pulser and two samplers is described. The apparatus calibrates itself automatically using the internal calibration standards.
Claims23
A network analyzer, comprising:
- one or more signal sources for generating one or more stimulus signals;
- one or more receivers for measuring one or more responses;
- one or more permanently connected internal calibration standards adapted to be switched in and out of a circuit to be calibrated;
- one or more device ports adapted to be connected to a device under test;
- and
- one or more switches for switching the one or more signal sources and one or more receivers between the one or more internal calibration standards and the one or more device ports.
