I'm reading the guide pna-x 67Ghz on the part (option 029 and 028 of the noise).
I have two questions
1 - how to choose the bandwidth of noise (.8 Mhz, 2 Mhz ,,,, 24Mhz) in option 029 and .7 Mhz and 1.2 Mhz for option 028? and what does the relationship with the DUT bandwidth? and how the bandwidth of noise intervenes to measure the product bandwidth gain during the calibration
2 - why was the calibration of the RF source using the power probe to be 0dbm?
thank you very much
