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。
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。
Passive intermodulation (PIM) is a form of intermodulation distortion that occurs in passive components such as antennas, cables, connectors, or duplexers with two or more high-power input signals.
无源互调(PIM)作为互调失真的一种,是由无源器件(例如天线、电缆、连接器或带有两个或以上大功率输入信号的双工器)产生的。
Our portfolio of current-steering DACs with differential outputs exhibit excellent SFDR (spurious-free dynamic range), IMD (intermodulation distortion), SNR (signal-to-noise ratio) and phase noise, in addition to extremely low glitch, fast settling time and low latency operation.
除了极低的毛刺干扰、快速稳定时间和低延迟操作特性之外,我们具有差分输出的电流导引 DAC 还拥有卓越的 SFDR (无杂散动态范围 ) 、 IMD (互调失真 ) 、 SNR (信噪比) 和相位噪声。
A third-order intermodulation distortion(IMD3) sinker composed of a PMOS FET and a tuned inductor is proposed for linearization of CMOS cascode LNA in this paper.
该文提出了一种由调谐电感和PMOS管构成的3阶互调失真吸收单元来提高线性度。
A comprehensive set of automatic frequency-domain measurements, including THD, THD+N, SNR, SINAD and intermodulation distortion can be added to the display.
一整套自动频域测量工具,包括 THD, THD+N, SNR, SINAD和互调失真,都能被添加到显示中。
Low cross-modulation and intermodulation distortion
低交叉调制和互调制失真
PScope can also perform more complicated calculations such as intermodulation distortion from a 2-tone test, or adjacent channel power ratios (ACPR) from a spread spectrum signal, and supports simultaneous evaluation of multiple channel ADCs.
另外,PScope 还可完成更加精细复杂的计算,例如:源自双音调测试的互调失真或者来自一个扩频信号的相邻通道功率比 (ACPR ) , 并支持多通道 ADC 的同时评估。
