Walter, The two OCXO are not electrically compatible, you can connect a 10811in an equipment wired for the 10544 but not the reverse. The 10811 is a SC cut crystal oscillator and the 10544 is an AT cut. The crystals are individually tested and the temperature is set at the best

Hi Perrier, The HP8405A is an analog vector analyzer that allows you to make phase measurements like the oscilloscope with Lissajous shapes. This method is the simplest one but allows quite approximate measurements and does not give you a complete view of stability (Allan Deviation).
