The 8484A used a single diode and had no temperature compensation , I think that HP tried to minimize the impact of temperature variations by using a heavier all metal case .... the 8481D uses a thermistor

OK Dave
Re the 8484 I actually have 2 of the black 2 grey and one D version a lot better than my original 430 power meter and Sensor with an N connecter on it So just a thought how dues the 8484A do its temperature compensation as I do not think I have ever looked at the CCT diagram for the 8484 A

The 8484A was the first diode sensor that HP produced , it was a horrible piece of equipment prone to drift especially if you got one with the black case .
Eventually HP redesigned the sensor to solve the issues and the new sensor was the 8481D

Of that there can be NO doubt. But we all love you anyway. ;)
