“…From the specification sheet of Agilent 3458A DVM, we get the uncertainty, caused by voltage measurement, of 0.0029 dB. One source of type IV power meter uncertainty is the drift of the thermistor bridge current and another one is the uncertainty caused by imperfect bridge balance [7]. The uncertainty caused by noise (short-term stability) is estimated to be smaller than 0.0011 dB.…”

We have developed two coaxial-type microwave attenuation standards using the power ratio transfer method. One standard operates in the frequency range of 18 GHz to 26.5 GHz, and has a dynamic range of 80 dB. Its expanded uncertainty (k = 2) is estimated to be 0.01 dB/80 dB. The other operates in the frequency range of 26.5 GHz to 40 GHz, and has a dynamic range of 60 dB and an expanded uncertainty of 0.009 dB/60 dB. We present an example for calibration of a 40 dB step attenuator using the attenuation standard in a series radio-frequency substitution scheme. The expanded uncertainty (k = 2) is 0.01 dB including the mismatch uncertainty.

This paper presents an accurate millimeter-wave attenuation measurement system in 140GHz-220GHz range. Based on the intermediate-frequency (IF) series substitution method, this measurement system employs an inductive voltage divider (IVD) working at 10 kHz as a reference standard. By stabilizing the IF measurement signal with a new reference signal generating technique, the system can get a pretty good stability just like shown in related figures. The validity of new system gets proved by comparing its measurement results with another dualchannel IF substitution system's results, which is a national metrology standard with 2 GHz substitution frequency. The achievable calibration accuracy and its measurement uncertainty evaluation are also analyzed and discussed in this paper.
