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

USB probe controller

Technical field

The present invention relates to a kind of USB probe controller.

Background technology

In October, 1999, SATIMO company of France trial-produceed a kind of multi-probe Antenna testing system successfully, this multi-probe test macro is different from traditional test macro, many probe technologies that it is started, bring more fast test Solution and test result more accurately to electromagnetism field, being a significant innovation of near-field test technology, is the great revolution of antenna measurement technology.Nowadays many probe antennas test macro has become the standard solution of wireless device test.The test speed that SATIMO is beyond challenge, means investment repayment faster.Test frequency range is extended to 70MHz to 18GHz by SATIMO in 2006 test macro of popping one's head in more, thereby make many probe technologies be widely used in the every field such as wireless, robotization, national defence, aviation.

In many probe antennas test macro, can apply to the multiple probe controller on RF (radio frequency) and control module, traditional multiple probe controller is intelligent not, control use loaded down with trivial details, and while being out of order without radio frequency interface for subsequent use, work is easily interrupted.

Summary of the invention

The technical matters that the present invention solves is for above-mentioned deficiency, a kind of USB probe controller is provided, the present invention realizes multiple probes and radio frequency interface is controlled, the present invention in connection, just can directly control the rotation of the probe in test macro and the break-make of radio frequency interface by simple and clear desktop application program on computers, thereby realize easy control.

Technical scheme of the present invention is as described below: a kind of USB probe controller, it is characterized in that, comprise usb data interface, single-chip microcomputer, field programmable gate array FPGA, data storage, level conversion circuit, interface circuit and peripheral feed circuit, described single-chip microcomputer connects respectively field programmable gate array FPGA and usb data interface, described field programmable gate array FPGA is connected with interface circuit by level shifting circuit, described data-carrier store is connected with described field programmable gate array FPGA, described interface circuit is linking probe controller respectively, radio-frequency switch circuit and electronic switching circuit, described usb data interface receives outer computer control signal and is sent to described single-chip microcomputer, described single-chip microcomputer converts its processing to level signal that field programmable gate array FPGA can directly read again, described field programmable gate array FPGA receives after signal on request control signal input interface circuit or be input to interface circuit through level shifting circuit respectively, thereby realize break-make to radio-frequency switch circuit and the control of probe.

Further, described interface circuit comprises DB15 interface circuit and DB26 interface circuit, described field programmable gate array FPGA is input to control signal respectively in the DB15 serial ports of appointment after receiving signal on request, this serial ports is controlled, thereby control the break-make of the radio-frequency switch circuit being connected with this interface circuit, four pairs of low and high levels of DB26 output are controlled to the RS232 serial ports being sent on control panel with one group of control signal to each electronic switch simultaneously and control, thereby realized the control to probe.

What further, described data storage was selected is flash chip.

Be according to above-mentioned beneficial effect of the present invention: realize multiple probes and radio frequency interface controlled, the present invention in connection, just can directly control the rotation of the probe in test macro and the break-make of radio frequency interface by simple and clear desktop application program on computers, thereby realize control and more accurately DATA REASONING easily, also prepared a radio frequency interface for subsequent use, to prevent that one of them interface from can not can also carry out gamut detection the used time simultaneously.
