So a lot of testing. The group applies the test signal, and enters 1 and then according to the thorn provided by the remote module can be completed in a given period. Therefore, the purpose of one of the inventions is also passed on. Improved test equipment to make it shorter to reduce test time. Another object of the present invention is to provide a receiver and an alternative method for testing the network cable in a more time efficient manner. It is yet another object of the present invention to provide a system and method for testing network cable improvements. The subject matter of the present invention is particularly pointed out and clearly claimed in the final part of this patent specification. However, the method of organization and operation, as well as further advantages and objects thereof, may be apparent by reference to the accompanying description and the accompanying drawings. [Embodiment] A system according to a preferred embodiment of the present invention includes a network tester °. 1 〇 to test the LAN cable. For example, a cable tester that tests four pairs of conductors is provided. In May, reference is made to Figure 1 which shows the circuit diagram of the configuration of the test instrument. The four pairs of pairs of cables 12, 12, 12, 'and 2' are transmitted through individual balance to unbalanced conversion. (balun) 4 is connected to the switch 16, the switch 16 includes a test signal transmitting switch l6a, a test signal receiving switch device for correction, in order to facilitate other tests when the thumb 拄T #°海非乜号源元元This measurement is performed to the H to be tested with no test signal yet. At the subsequent time slot 'the source unit 胄NE II & 12 (to the near-end crosstalk); and the non-signal source unit uses the test signal applied by the S source unit to measure FEXT M (paired telescope '1 to 3 far-end crosstalk). In the next time slot, the source unit measures the near-end crosstalk of the power line 13 and the non-signal source unit measures FEXT 1,2. Thereafter, the signal source applies a test signal to measure ΝΕχτ 1 '4 (the transmit switch 16 6 is closed to apply the test signal to the paired cable tap 1 ' and the receive switch 16 b '' ' is also closed to accept Return crosstalk on paired cable 4). At this time, the non-signal source unit measures the insertion loss (insertion 1 〇 ss) of the cable 1 (this is the transmission loss of the end point to the end point of the cable).
接下來，該信號源單元係藉由判斷反射信號與入射信 號之比例，以量測成對電纜線i之回波損耗（R]L 1);而該 非仏唬源單元則利用信號源單元施加之測試信號，以量測 成對電纟覽線1至4之遠端串音（FEXT 1，4)。量測係繼續進 行 ’ ^ 號源端恢序決定 NEXT 2,3、NEXT 2,4、RL 2、NEXT 3,4、與RL 3 ;而非信號源端對應的依序則係FEXT 2,4、IL 2、FEXT 2,3、IL 3、與 FEXT 3 4。 在信號源瑞RL· 3量測時槽、與非信號源端FEXT 3,4 星測時槽的後續之時槽中’該信號源端具一個沒有源自該 端點的量測之時槽’而該非信號源端則量測成對電纜線4 之插入損耗（IL 4)。接著，接下來之時槽中，該信號源端 1380032 : i測RL 4(成對電繞線4之回波損耗），而該非信號源端則 加一被動1 〇〇歐姆之终端阻抗至該待測電纜線且係處 於被動終端模式。信號源端接續之四個時槽係Quiet卜Quiet 2、 Quiet 3、與 Quiet 4 ,而非信號源端則係 Quiet 4、Quiet 3、 Quiet 2、與Quiet 1。在這些時槽之每一時槽中，信號 源端與非信號源端皆保持靜默其中源自該測試儀器之該 信號源係被關閉，而量測則於特定成對電纜線進行（例如，Next, the signal source unit measures the return loss (R]L 1 of the pair of cable lines i by determining the ratio of the reflected signal to the incident signal; and the non-power source unit is applied by the signal source unit The test signal is measured to the far-end crosstalk (FEXT 1, 4) of the pair of power line 1 to 4. The measurement system continues with the '^ source source sequence decision NEXT 2,3, NEXT 2,4, RL 2, NEXT 3,4, and RL 3; the non-signal source corresponds to the sequence FEXT 2,4 , IL 2, FEXT 2, 3, IL 3, and FEXT 3 4. In the subsequent slot of the signal source RL·3 measurement time slot and the non-signal source terminal FEXT 3,4 star time slot, the signal source end has a time slot without measurement from the end point. 'The non-signal source is measured as the insertion loss (IL 4) of the cable 4. Then, in the next slot, the signal source terminal 1380032: i measures RL 4 (the return loss of the pair of electrical windings 4), and the non-signal source terminal adds a passive 1 ohm ohm terminal impedance to the The cable to be tested is in passive terminal mode. The four time slots connected to the source are Quiet Bu Quiet 2, Quiet 3, and Quiet 4, and the non-signal source is Quiet 4, Quiet 3, Quiet 2, and Quiet 1. In each of these time slots, both the source and the non-signal source remain silent, wherein the source from the test instrument is turned off and the measurement is performed on a particular pair of cable lines (eg,
Quiet 1 i測成對電徵線1，Quiet 2量測成對電缓線2、等 |等），以判斷可能由外部信號源造成之任何電磁干優或其 它雜訊是否存在。 在上述測試序列完成之後，接著該信號源端與該非信 號源端交換，因而第二儀器部分34現在變為該信號源端， 且將會進行該測試時槽序列36 ;而先前係該信號源端之第 一儀器部分30現在變成該非信號源端，進行該測試時槽Quiet 1 i measures the signal line 1, Quiet 2 measures the pair of lines 2, etc., etc., to determine whether any electromagnetic interference or other noise may be caused by an external source. After the test sequence is completed, the signal source is subsequently exchanged with the non-signal source, so that the second instrument portion 34 now becomes the source of the signal, and the test slot sequence 36 will be performed; The first instrument portion 30 of the terminal now becomes the non-signal source terminal, and the test slot is performed.

In this manner, the sequences of the tests are all performed from each end of the cable. The grading continues with reference to Fig. 6, which shows the specific detail of the one-time slot sequence measurement, which in this example is the NEXT 2, 3 time slot of the source unit. The particular time slot begins with a gain setting portion that continues for 64 在 in the illustrated embodiment to set the instrument gain to an appropriate level. Next, a set of N 64 μ5 measurements is performed to provide an average function, with the 平均 average factor.
