Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

본 발명에 따른 구내커넥터 성능 평가 측정 시스템은 도 1의 블록 구성도에 나타낸 바와 같이, 네트웍 분석기(110), 발룬 픽스처(120), 성능 평가 프로그램(131)이 내장된 PC(130), 영점 조정 기구(140)로 이루어진다.In the premises connector performance evaluation measurement system according to the present invention, as shown in the block diagram of Figure 1, the network analyzer 110, the balun fixture 120, the PC 130 with the performance evaluation program 131, zero adjustment Consists of a mechanism 140.

발룬 픽스처(120)는 시료(Device Under Test; DUT)인 구내커넥터와 측정 장비인 네트웍 분석기(110)를 연결시켜 구내커넥터 페어의 접속 용이성 및 시험 반복성을 제공하는 구조로서, 불평형 신호를 평형 신호로 변환 및 임피던스 변환 역할을 하는 발룬(Balun : Balanced to Unbalanced)을 내장한 픽스처이며, 접속기구 및 이에 연결된 발룬은 고주파수의 전기적 성능 시험시 발행할 수 있는 각 페어간의 간섭을 제거하기 위하여 도체로 차폐되어 있다.The balloon fixture 120 is a structure that connects an internal connector, which is a device under test (DUT), and a network analyzer 110, which is a measurement device, to provide easy connection and test repeatability of the internal connector pair, and converts an unbalanced signal into a balanced signal. Fixture with a built-in balun (balanced to unbalanced) that acts as a conversion and impedance conversion, and the connecting device and the balun connected to it are shielded with conductors to remove interference between pairs that can be issued during electrical performance test of high frequency. have.

영점조정 기구(Calibration Kit; 140)는 Open/Short/Load/Through 기구로 구성되며, Load 기구는 시료인 구내커넥터의 특성 임피던스와 동일한 칩저항을 사용하고, 그 외는 시료 접속을 위해 사용되는 리드선과 동일한 평형 케이블로 제작된다.The calibration kit (140) consists of open / short / load / through mechanisms.The load mechanism uses the same chip resistance as the characteristic impedance of the premises connector, which is a sample, and the other leads and wires used for sample connection. Made of the same flat cable.

PC(130)에 내장된 성능 평가 프로그램(131)은 네트웍 분석기(110)를 원격 조정하여 성능 시험 전 영점 조정과 구내커넥터의 성능 평가를 위한 시험 항목인 감쇠, 근단누화, 원단누화, 반사손실, 전파지연, 지연왜곡을 측정하며, 각 시험 항목에 대한 카테고리 3, 카테고리 4, 카테고리 5, 카테고리 5E, 카테고리 6 등의 표준 규격을 내장하여 선택 가능하고, 측정 데이터와 표준 규격과의 비교 데이터를 그래프 형태로 출력한다. 그리고 측정 데이터 및 적용된 표준 규격은 파일로 출력함으로서 데이터 관리가 가능하다.The performance evaluation program 131 built into the PC 130 remotely controls the network analyzer 110 to test the zero point before the performance test and to evaluate the performance of the premises connector, attenuation, near-end crosstalk, far-end crosstalk, reflection loss, Measures propagation delay and delay distortion, and selects built-in standards such as category 3, category 4, category 5, category 5E, and category 6 for each test item, and compares the measured data with the standard. Output in the form In addition, measurement data and applied standard specifications can be output to a file for data management.

이와 같이 구성된 본 발명에 따른 구내커넥터 성능 평가 측정 시스템에 의한 측정 과정을 도 1 및 도 2를 참조하여 아래에서 상세히 설명하기로 한다.The measurement process by the premises connector performance evaluation measurement system according to the present invention configured as described above will be described in detail below with reference to FIGS. 1 and 2.

먼저, PC(130)에서 성능 평가 프로그램(131)을 실행한 후에 카테고리 3, 카테고리 4, 카테고리 5, 카테고리 5E, 카테고리 6 등의 성능에 대한 표준 규격 중 적용할 성능 규격을 선택한다(201). 예로 TIA/EIA 569-A 카테고리 5 규격을 선택했을 경우 측정 주파수 대역은 1∼100㎒이며 401 포인트 측정 및 출력전력을 선택할 수 있다.First, after executing the performance evaluation program 131 in the PC 130, a performance standard to be applied is selected from among standard standards for performance of category 3, category 4, category 5, category 5E, category 6, and the like (201). For example, if the TIA / EIA 569-A Category 5 standard is selected, the measurement frequency band is 1 to 100 MHz, and 401 point measurement and output power can be selected.

다음으로, 영점 조정 기구(140)를 이용하여 네트웍 분석기(110)의 기준점 영점 조정을 수행하여 성능 측정에 영향을 미칠 수 있는 시료 이외의 여러 요소를 제거한다(202).Next, zero point adjustment of the network analyzer 110 is performed using the zero point adjusting mechanism 140 to remove various elements other than the sample that may affect the performance measurement (202).

시료인 구내커넥터가 접속되는 부분을 기준면이라 하는데 발룬 픽스처(120)의 평형 단자가 여기에 해당한다. 2-포트 칼리브레이션(Calibration)을 수행하는것이 바람직하며, 영점 조정 후에 로드(Load) 기구에 의한 반사 손실이 40㏈ 이상이고, 노이즈 플로어(Noise Floor)가 80㏈ 이상이어야 한다.The part where the internal connector, which is a sample, is connected, is called a reference plane, and the balanced terminal of the balun fixture 120 corresponds to this. It is preferable to perform a two-port calibration, the return loss by the load mechanism after zero adjustment should be 40 kW or more, and the noise floor should be 80 kW or more.

이후, 기준면에 시료인 구내커넥터를 접속한 후에 실제 각 시험 항목에 대한 시험을 수행한다. 감쇠 측정구성과 전파지연, 지연왜곡은 같은 측정구성에서 측정한다(211∼213). 근단누화 측정, 원단누화 측정과 반사손실 측정은 서로 다른 측정구성을 가지며 이를 시험 방법 기술 표준에 의거하여 정확히 구성한 후에 측정한다(221∼241).Then, after connecting the internal connector as the sample to the reference plane, the test for each test item is performed. The attenuation measurement configuration, propagation delay and delay distortion are measured in the same measurement configuration (211 to 213). Near-end crosstalk measurement, far-end crosstalk measurement, and return loss measurement have different measurement configurations and are measured after being correctly configured according to the test method technical standard (221 to 241).

상기와 같은 절차에 의하여 얻어진 측정 데이터는 네크웍 분석기(110)로부터 PC(130)로 전송되며, PC(130)에 내장된 성능 평가 프로그램(131)에 의하여 각 시험 항목의 측정 결과는 표준 규격과 비교 출력됨과 아울러 데이터 파일로도 저장된다. 이를 바탕으로 시료의 적용할 표준 규격에의 접합성 여부를 판단한다(251).Measurement data obtained by the above procedure is transmitted from the network analyzer 110 to the PC 130, the measurement results of each test item by the performance evaluation program 131 built in the PC 130 and the standard specification In addition to the comparison output, it is also saved as a data file. Based on this, it is determined whether the sample adheres to the standard specification to be applied (251).

전술한 바와 같은 본 발명은 컴퓨터에 내장된 성능 평가 프로그램을 이용하여 네트웍 분석기를 원격 조정하여 구내커넥터의 각종 시험 항목을 측정한 후 측정 데이터와 함께 표준 규격과의 비교 데이터를 출력함으로써, 측정 작업의 용이성이 제고됨과 아울러 성능 평가의 신뢰성이 향상되는 효과가 있다.The present invention as described above, by measuring the various test items of the premises connector by remotely controlling the network analyzer using a performance evaluation program built into the computer, and outputs the comparison data with the standard specification along with the measurement data, In addition to improving the ease of use, the reliability of the performance evaluation is improved.
