When design mobile phone pcb board, need on handset single-plate, reserve the test point of baseband functions and radio frequency.Wherein, radio frequency testing is that test probe and the radio frequency testing point on the veneer on the test clamp 102 keeps excellent contact, under the state of veneer start, and the radio frequency testing software of operation mobile phone on PC.PC links to each other with comprehensive test instrument by GPIB, links to each other with test fixture 102 by the RS232 serial ports, carries out the transmission of various control commands and data.Like this, just can judge by the implementation status of observation radio frequency testing software whether the radio-frequency performance of veneer is good.
Radio frequency testing software in the scheme is to aim at radio frequency testing and write.After handset single-plate powers on, operation radio frequency testing software on PC.Radio frequency testing software carries out RF calibration and survey eventually to mobile phone successively according to test request.
Fig. 2 is the system construction drawing of double-mode single-standby handset single-plate radio frequency testing device according to an embodiment of the invention.As shown in Figure 2, this device comprises:
Test fixture 102, profile according to handset single-plate designs, and the metallic test probe is installed on test fixture 102 according to the position of single-board testing point, and also have a radio frequency interface to link to each other on the test fixture 102 with test probe, also leave power input interface and serial ports in addition.The main effect of test fixture 102 comprises: fixing handset single-plate contacts test point on the veneer by the metallic test probe on the anchor clamps.
Testing cassete 104, form by SPDT switch and logic control circuit, in order to the radio-frequency channel of handset single-plate and described two comprehensive test instruments is switched, this testing cassete 1 port is by the radio frequency test interface on the radio frequency cable connection test fixture 102,2,3 ports connect first comprehensive test instrument 108 (standard 1) and second comprehensive test instrument 110 (standard 2) respectively, VCC is the power supply input port, and CTL is the signal input end mouth.
The output of second comprehensive test instrument 110, a tunnel is connected to the metal probe of veneer power supply and the VCC port of described testing cassete by on lead and the test fixture 102, and its effect provides suitable operating voltage and electric current to handset single-plate and logic control circuit; Another road output is connected with the CTL port of described testing cassete 104, is used for controlling the switching of radio-frequency channel.
Two comprehensive test instruments (first comprehensive test instrument 108, second comprehensive test instrument 110), the test of first comprehensive test instrument, 108 corresponding standards 1, the test of second comprehensive test instrument, 110 corresponding standards 2, be connected with the radio frequency test interface of handset single-plate by described testing cassete 104, in order to handset single-plate carried out the radio-frequency (RF) index calibration and to survey eventually.
All-purpose computer 202 (control device) is connected with described two comprehensive test instrument control ends, in order to control two comprehensive test instrument work; Also link to each other, in order to control its output voltage and electric current with described dual-output power supply 112; And link to each other with described test fixture 102, in order to carry out transfer of data (as writing of calibration data or the like) with handset single-plate; Described computer is connected with described two comprehensive test instrument control ends and described dual output power control terminal by gpib bus, is connected with described test fixture 102 by the RS232 serial ports, is used for the transmission of various control commands and data; Wherein, all-purpose computer 202 is provided with serial ports and at least one gpib interface card.
Thereby all-purpose computer 202, two comprehensive test instruments, handset single-plate, test fixture 102 and testing cassetes 104 have constituted the single board radio index testing device, it is calibrated the radio-frequency (RF) index of veneer and surveys eventually by moving corresponding program, makes it reach designing requirement.
