WS PRO方案跟DCM+VNA的方案的請(qǐng)看附件.而所有的測(cè)試方案都是根據(jù)ANSI/TIA/EIA-568-B.2-10的標(biāo)準(zhǔn)進(jìn)行
一,使用WS PRO能完成以下重點(diǎn)參數(shù)的測(cè)試,此方案的價(jià)格在20萬(wàn)左右,實(shí)驗(yàn)室及工程方案

二,使用DCM+NA測(cè)試方案可得出如下參數(shù),此方案的價(jià)格在200萬(wàn)左右,實(shí)驗(yàn)室方案
Insertion Loss (Attenuation) | Attenuation to Crosstalk Ratio |
NEXT Loss (Near End Crosstalk) | Velocity of Propagation (VoP) |
FEXT Loss (Far End Crosstalk) | TCL and TCTL (optional) |
Crosstalk Power Sums | Transfer Impedance (optional) |
Structural Return Loss (SRL) | Screening Attenuation (optional) |
Return Loss (RL) | Capacitance and Resistance |
Propagation Delay and Delay Skew | Capacitance Unbalance |
Impedance (Input and Characteristic) | Resistance Unbalance |

夸張，用安捷倫的網(wǎng)絡(luò)分析儀就搞得定了!!!
