Hello,

I am using 81624A with 81002FF integrating sphere to make high power measurement (+30dBm) but I do not know what corrective factor should be applied between power value read and real power value. All info I found on Agilent website was that this sphere gave roughly 41dB attenuation. where can I found more detaiiled on this product?

Thanks,

This attachment was not factory calibrated and does have wavelength dependence, so for accurate absolute power measurements it should be calibrated together with the power head, as described under the chapter for absolute power measurement in this guide.
