Summary of the invention

The purpose of this utility model is, provides that a kind of to detect LAN (Local Area Network) mutually with the width of cloth be support, is unit with the phase shifter, detects the multifrequency point width of cloth phase data of a certain phase shifter of single T/R assembly automatically and calculates error correction values, and is easy to use, simple to operate; Testing result and error correction values can be stored in the T/R component internal, need not use the excessive data storehouse; Having overcome prior art, to take database volume big, substitutes loaded down with trivial details disadvantage, realizes detecting at a distance, uses manpower and material resources sparingly, and system database is safeguarded simply at wire spoke phase pick-up unit.

The utility model is to realize above-mentioned purpose by following technical solution:

A kind of at wire spoke phase pick-up unit, it is made up of T/R assembly control panel, router, computing machine, vector network analyzer and signal source, it is characterized in that: router is connected with vector network analyzer, signal source, computing machine respectively by netting twine, and computing machine connects T/R assembly control panel by Serial Port Line; Described T/R assembly control panel is made up of FPGA programmable logic device, RS232 serial communication integrated package, storage integrated package; The input end of FPGA programmable logic device connects 50M crystal oscillator and jtag interface respectively, and jtag interface is connected with USB and downloads line, and downloads line connection storage integrated package by USB; The FPGA programmable logic device connects RS232 serial communication integrated package by Serial Port Line.

The utility model beneficial effect compared with prior art is:

Should adopt T/R assembly control panel, computing machine, vector network analyzer, signal source, router to form LAN (Local Area Network) at wire spoke phase pick-up unit, debug process is not subjected to the restriction of T/R assembly deposit position, can realize remote detection, save the manpower and materials of radar debugging work; Automatically finish the detection of multifrequency point, reduced the debugging work load of radar; Install the storage integrated package additional on T/R assembly control panel, error correction values can directly leave the T/R component internal in, has simplified the control of radar beam controlling system, has reduced the debugging work load of radar, makes the maintenance of system database convenient.
