Measurement of Noise Figure of LNA

IN my lab ,there is a PNA N5247 without options 029, if i want to measure the NF ,i must buy options 029,but i have found that the options 029 is too expensive to me .so i must find other method to measure the noise figure ,there is a N8975A in my lab too, but its maximum frequency is 26.5G ,so i must add blockdown converter ,N8975AZ-K40/K50 is a blockdown converter for N8975A by agilent ,but it is also expensive . more than S50.000 . our lab cann`t afford this . i want to measure the NF using money blow S5.000. so do you have any suggestion for me to achieve this .thanks

Just quoting model numbers without even a manufacturers name is of no use to most members of this forum. What you need is a CW signal source with a calibrated attenuator, a receiver with an IF output and a RMS power meter that is accurate at IF and an input termination resistor. So what have you not got?

Why are you starting another thread to ask this. You have asked the same question at

RMS power is a useless entity. One can mathematically compute the RMS value of any function, but in the case of power it is pointless to do so, since the result has no particular use. In general, it will not have the same heating effect as the mean value of power. In contrast the mean power is a useful quantity.
