SELT abbr. 单端线路测试(Single-Ended Line Testing)
- SELT can reduce operators' costs and thereby the customer's subscription cost.
SELT能降低运营商的成本进而是用户的花费。 - Unfortunately, lack of calibration of these components can effectively limit the working range of SELT.
不幸的是,缺少这些元件的校正会有效的限制SELT的工作范围。 - This section presents two examples that illustrate the impact of component tolerance on SELT accuracy and the improvements possible via calibration.
本节用两个例子说明元件公差对SELT精确度的影响以及通过校正可能的改进。
