WS PRO方案跟DCM+VNA的方案的請看附件.而所有的測試方案都是根據(jù)ANSI/TIA/EIA-568-B.2-10的標(biāo)準(zhǔn)進(jìn)行
一,使用WS PRO能完成以下重點參數(shù)的測試,此方案的價格在20萬左右,實驗室及工程方案

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 |
