Background technology
Along with the development and the evolution of the communication of mobile communication technology especially 3G, many wireless terminals all combine 2G (for example GSM) and 3G (for example TD-SCDMA) technology, and support the required high data rate of mobile Internet.In order to make the user can enjoy 2G and 3G service simultaneously, can both be operated in multiband and can support dual mode operation based on the wireless terminal major part of 3G.
For user and network vendors, possessing all these functions is good things, but they have brought challenge to the Test Engineer.Therefore the communication technology of every kind of interpolation and frequency band have all increased test job, cause the time of production test procedure longer thus, and testing cost increases, this obviously and people wish that the expectation that reduces the wireless communications products price is not inconsistent.
With reference to Fig. 1, wireless terminal generally can be done following two steps operation to less radio-frequency when carrying out production test:
The first step is the RF calibration test, that is, radio frequency unit is calibrated to eliminate radio frequency chip and element in the diversity aspect frequency and the level nature.In most cases, manufacturer need carry out frequency calibration (AFC), transmission power calibration (AGC) and received signal intensity indication (RSSI) calibration to each wireless communication frequency band and the various communication technology.
Second step was the radio-frequency performance test, that is, checking can be worked as expecting through the wireless terminal of calibration comprehensively.At transmitter, manufacturer measures as emission parameters such as modulation quality, frequency spectrum, power, and test result and the defined parameter of various criterion are compared; At receiver, in most cases, the absolute sensitivity of receiver is determined by bit error rate (BER) test.
At present, GSM supports 4 frequency ranges (850MHz, 900MHz, 1800MHz, 1900MHz), and TD-SCDMA supports two frequency ranges (1880MHz, 2010MHz), expands to the frequency range with support 2300MHz.The fusion of so many frequency range and different communication technology all can prolong calibration and verify this two processes.In this method, the first step is carried out under non-signaling mode, and equipment under test wherein (DUT) is operated in test pattern, and tester comprises radio frequency analyzer and radio freqnency generator, but does not need the function of real-time simulation base station or network.Second step carried out under signaling mode, tester is a signalling tester of supporting the various communication technologys, by the various functions of signalling tester real-time simulation base station and network, changeable all communication technologys to be measured of the signaling procedure that is used to test, frequency band, level or the like.
Because the first step and second pattern that is adopted are different, tester is also different, and this difference has been brought the counter productive of following two aspects:
(1) because the test in second step is to finish under signaling mode, the wireless terminal expensive time of meeting especially when the switching that communicates technology, needs a large amount of Signalling exchange and extremely unstable in the foundation of signaling process with alternately.
(2) owing to use test instrument in two steps is different, for manufacturer, need the extra signalling tester of buying, this has increased production cost and input greatly.
