FAQ 2011-10-07

4395A 是否具有源功率校准功能?
否,4395A 不具备在测试端口校准源功率的内置功率计。源功率精度为 +/- 1.0 dB。

FAQ 2010-01-26

有没有可以支持频率低至 9 kHz 的 E5071C 的电子校准?
有,N4431B 4 端口电子校准现在可以支持低至 9 kHz 的频率。

FAQ 2009-11-16

Is the accuracy of the impedance measurement specified when the 4395A/4396B Option 010 is used with the 87512A?
No, the accuracy of the impedance measurement values obtained by using the 4395A/4396B with the 87512A is not specified.

FAQ 2008-11-16

Can the spectrum analyzer mode of the 4395A display noise level below 0.0001 µV / sqrt (Hz) in noise measurement mode?
No, the 4395A can't display noise level below 0.0001 µV / sqrt (Hz) in noise measurement mode.

FAQ 2008-11-16

Is there any method of measuring impedance at low frequencies below 100 kHz with the 4395A-010?
The option 4395A-010 is designed to measure impedance at frequencies above 100 kHz and, thus it is specified for the range above 100 kHz.

FAQ 2008-06-12

我在使用是德阻抗分析仪测量电容器时,Q和D出现了负值,我该如何处理呢?
对于低损耗器件(高Q、低D)来说,在LCR表/阻抗分析仪上通常不会出现负读数。请注意负读数在物理上是不可能的(对于无源元件),下面的内容解释了出现负读数的原因。
