E4418B中1 mW参考的规格包括短期和长期稳定性。
在23摄氏度+/- 3摄氏度规格范围内，您的测量值远低于+/- 0.5％。
因此它通过了校准测试。由于E4418B的1 mW参考信号，热敏电阻安装座及其电缆以及您正在使用的432A / 3458A的温度和时间不稳定性，您将在一段时间内获得信号电平的一些变化。
所有这些变量都应包含在进行校准时使用的不确定度分析中。但你没事。
你在规范范围内。

The specifications for the 1 mW reference in the E4418B include short term and long term stability. Your measured value is well within the +/-0.5% over the 23 degree C +/- 3 degrees C specification. So it passes it calibration test.
You will get some variation in signal levels over time due to temperature and time instabilities in both the E4418B's 1 mW reference signal, the thermistor mount and its cable, and the 432A/3458A you are using. All of these variables should be included in the uncertainty analysis you are using when making this calibration.
But you are fine. You are within spec.
