using 85024A with spectrum analyzer N9000A

hi all,

i am using probe 85024A to measure DUT and notice that there is 10dB drop for the result measurement using my N9000A spectrum analyzer.

as this is a resistive probe 10:1 i am expecting a 20dB drop instead of 10dB drop.

i also realize that it's a 1Mohm impedance versus my instrument 50ohm.

how would i calculate and would expect a 10dB drop rather 20dB drop?

thanks you.
