Embodiment Construction

[0031] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] In the preferred embodiment, the automatic measurement controller selects a GPIB-ETH (General Interface Bus-Ethernet Port) controller, and the GPIB-ETH controller is provided with a serial port and an Ethernet interface at the same time.

[0033] refer to figure 1 As shown, the GPIB-ETH controller realizes the data and waveform of the test instrument collected locally or remotely. The outdoor unit (ODU, out door unit) device is used to convert the satellite C-band and KU-band signals into baseband signals. Test instruments include spectrum analyzers, noise analyzers, signal sources, and oscilloscopes. The ODU equipment is connected with the test instrument, and the output of the above test instrument is connected to the GPIB-ETH controller through the GPIB cable. The GPIB-ETH controller is connected to the remote notebook computer thro...

Abstract

The invention discloses an automatic measurement controller, comprising an embedded controller and a GPIB bus, wherein the embedded controller via data and address bus is connected with a SDRAM and a Flash, the GPIB bus is used to connected with GPIB external device, the automatic measurement controller is powered by a power system, the embedded controller is arranged with a MAC chip and an Ethernet transformer. And the automatic measurement controller also comprises a CPLD, a GPIB main control chip, a GPIB data bus drive chip, and a GPIB bus control signal drive chip. Therefore, user can use Ethernet and serial port to communicate with a tester on the GPIB bus, to easily control the tester via a computer, to collect and store the data and wave shape of the tester, thereby analyzing the data and the wave shape.

Description

technical field [0001] The invention relates to an automatic measurement technology, in particular to an automatic measurement controller. Background technique [0002] The automatic test system based on GPIB is the product of the combination of computer technology and automatic test technology, and it is widely used in many fields at present. A typical general purpose interface bus (GPIB, General Purpose Interface Bus) measurement system is composed of a PC, a GPIB interface card and several GPIB instruments connected by a standard GPIB cable, and the GPIB interface card completes the connection between the GPIB bus and the PCI bus. [0003] The GPIB bus is a digital 24-pin (flat interface socket) parallel bus. Among them, 16 wires are signal transmission wires, including 8 bidirectional data wires, 5 interface management wires, 3 data transmission control wires, and the other 8 wires are ground wires and shielded wires. GPIB uses 8-bit parallel, byte serial, and asynchro...
