Has anyone experimented with the amount of insulation on a 10544 or 10811 oscillator? They are meant to run hot by design and I worry that adding any insulation, or too much insulation, will either cause over-heating or limit the ability of the oven control to maintain the set point. None of the hp/Agilent bench test equipment that uses these oscillators uses insulation. Perhaps that's a clue. /tvb
The amount of insulation that can be used is limited by the thermal overhead inside the oven, and is a function of the oven set point and maximum ambient temperature. High thermal gain is achieved by controlling gradients, as explained in my 1997 IEEE FCS paper on ovens. Also read the HP Journal article on the 10811.
