They are used to verify intermodulation test benches for an instant and/or long-term level stability monitoring.
它们用于验证互调测试台,以进行即时和/或长期电平稳定性监控。
Poorly maintained or dirty equipment, improperly torqued connectors, ferromagnetic materials, minor damages to components enable two or more signals to mix and create intermodulation distortion.
维修不善或设备污浊、连接器紧固有误、铁磁材料、对部件的轻微损坏等都会使两种或更多的信号混合,从而产生互调失真。
Passive intermodulation occurs when two or more signals mix together or multiply in a passive non-linear device.
当两个或多个信号混合在一起或在一个无源的非线性设备上叠加时,就会发生无源互调。
Exceptional transmitter linearity vastly reduces frequency intermodulation, allows more compatible channels per frequency range
发射机卓越的线性度可大幅降低频率互调,每个频率范围内最多可兼容20个通道
These detailed measurements provide customers with a full picture of how well the network is operating in terms of performance, coverage and data traffic capacity, while identifying potential issues related to interference or intermodulation that need to be resolved.
通过这些详细的测量,客户将能全面了解网络在性能、覆盖范围和数据业务容量方面的表现,同时发现需要解决的干扰或互调相关的潜在问题。
In cellular communications, where multi-carrier and multi-band operation is increasingly prevalent, unwanted intermodulation products can fall onto receive bands, raising the noise level and degrading system performance.
在蜂窝通信中,多载波和多频段工作方式越来越普遍,一些多余的互调产物可能会进入接收频段,从而导致噪声电平上升,系统性能下降。
Reliable and repeatable intermodulation measurements
可靠且可重复的互调测试
For example, if you do not see two signal generators listed on the report showing the test equipment used for calibration, the third order intermodulation distortion (TOI) specification you needed was not increases the risk that your test equipment is out-of-specification and your test results may, therefore, be incorrect.
例如,如果在您的报告中用于校准的信号发生器只有一台而不是两台,或者您所需要的三阶互调失真(TOI)指标没有经过校准的话,那么,您的测试设备就会有很大的风险处于超差情况,并由此导致您的测试结果可能会不正确。
Features: High power gain, low noise figure, very low intermodulation distortion.
特点: 高功率增益,低噪声输出,非常低的互调失真。
If the third-order intermodulation value, displayed by the test instrument, deviates from the specified value of the intermod standard, it indicates a general measurement uncertainty which may be caused by the test setup rooting in one or several component or interconnection PIM sources.
如果测试工具显示的第三级互调值与规定的互调标准值有差异,表明存在一般的测试不确定性,这可能是由一个或几个组件或互连 PIM 资源内的测试装置加固引起的。
PIM creates a challenge for every company that is developing components and maintaining networks as the passive intermodulation originates from signal degradation effects of passive elements within the transmission system.
无源互调 (PIM) 为所有正在开发组件和维护网络的公司带来了挑战,因为无源互调是由传输系统中无源元件的信号劣化效应引起的。
Multi-carrier applications with high RF peak power and special passive intermodulation requirements are covered by series 3409.
具有高 RF 峰值功率和特殊无源互调要求的多载波应用,适配 3409 系列。
