有什么方法或威廉希尔官方网站 可以改善或稳定S11参数的测量？

你好。
我正在使用超薄型探头（来自85070介电套件）和e5072a VNA。
我对高介电常数材料（接近水）的测量有些麻烦，例如90％的水和10％的乙醇，当我重复测量介电常数时，实际部分会在很短的时间间隔内发生变化，有时候
它重新调整74，其他73,76,75 ......所以S11也在改变。
我们正在控制样品的温度（这是一个很大的瓶子，尝试持有者影响最小）并且它是相当稳定的......有什么方法或威廉希尔官方网站 可以改善或稳定S11参数的测量？
谢谢。

  Hello.

I'm working with both the slim form probe (from the 85070 dielectric kit) and the e5072a VNA. I'm having some trouble with the measurements of high permittivity materials (close to water), for example 90% of water and 10% ethanol, when i repeat the measurement of the permittivity the real part changes in a short gap of time, sometimes it returs 74, other 73, 76, 75... so the S11 is also changing.

We are controlling the temperature of the sample (which is in a big bottle, trying that the holder affects minimally) and it's quite constant...  

It's there any way or tecnique to improve or stabilize the measurement of the S11 parameter for this matter?

Thanks.
