Patent ID: 8823392

Claim:
A web-enabled electronic controller for controlling an impedance tuner in an RF measurement system, the impedance tuner including an RF signal transmission line and an electronically-controllable impedance-varying system coupled to the signal transmission line for controlling the impedance presented by the signal transmission line, the web-enabled controller comprising; an electronic processor configured to process external command signals and generate electronic control signals to configure the impedance-varying system of the impedance tuner in response to the command signals; an electronic memory for storing sets of data and one or more web pages; a communication server with an Internet Protocol (IP) address, the server supporting HTTP (Hypertext Transfer Protocol) communication and configured to receive or send signals through a TCP/IP communication channel from or to a client computer system; the communication server configured on said IP address to be responsive to an HTTP request message from a client computer system to send a response comprising the web page to the client computer system; the controller configured to process commands received from the client computer system through the communication server into the electronic control signals and to control the impedance-varying system of the impedance tuner during a measurement or calibration process conducted by the RF measurement system, and wherein during the measurement or calibration process first and second input/output ports of the impedance tuner connected to the RF signal transmission line are connected to at least one of the DUT, a signal source, a termination, a network analyzer or equipment, and the RF measurement system is configured during a measurement process to measure characteristics of a device under test (DUT) connected to the RF measurement system by sampling and measuring signals applied to and coming from the DUT.
