usb probe controller

Abstract

The invention discloses a USB probe controller which comprises a USB data interface, a single-chip microcomputer, an FPGA, a data storage device, a level conversion circuit, an interface circuit and a peripheral power supply circuit. The interface circuit is respectively connected with a probe controller body, a radio frequency switch circuit and an electronic switch circuit, the USB data interface receives external computer control signals and transmits the external computer control signals to the single-chip microcomputer, the single-chip microcomputer processes and converts the signals into level signals capable of being directly read by the FPGA, the FPGA receives the signals and respectively inputs control signals into the interface circuit or into the interface circuit through the level conversion circuit according to needs, and therefore the radio frequency switch circuit can be switched on and off, and probes can be controlled. According to the USB probe controller, the probes and a plurality of radio frequency interfaces can be controlled, rotation of the probes in a testing system and on-off of the radio frequency interfaces can be directly controlled through a simple and clear desktop application program in a computer, and therefore easy control and more accurate data measurement can be achieved.

Description

technical field [0001] The invention relates to a USB probe controller. Background technique [0002] In October 1999, the French company SATIMO successfully trial-produced a multi-probe antenna test system. This multi-probe test system is different from the traditional test system. Test solutions and test results are a major innovation in near-field test technology and a major revolution in antenna test technology. Multi-probe antenna test systems are now the standard solution for wireless device testing. SATIMO's unrivaled testing speed means faster return on investment. In 2006, the SATIMO multi-probe test system extended the test frequency band to 70MHz to 18GHz, so that multi-probe technology is widely used in wireless, automation, national defense, aviation and other fields. [0003] In the multi-probe antenna test system, the RF (radio frequency) and multi-probe controllers on the control unit are used. The traditional multi-probe controllers are not intelligent en...

Problems solved by technology

[0003] In the multi-probe antenna test system, the RF (radio frequency) and multi-probe controllers on the control unit are used. The traditional multi-probe controllers are not intelligent enough, the control is cumbersome, and there is no spare radio frequency interface when a fault occurs, and the work is easily interrupted.
