Noise figure, gain, and uncertainty

Without a Preamp

When combined with the U7227A/C/F preamp, the NFA X-Series noise figure analyzer

offers improved uncertainty over the previous NFA-A in all of the above hypothetical

cases.

1.

These uncertainties assume a measurement made with a N8975B at 1 GHz with a N4000A noise

source and a non-frequency-converting DUT. The DUT is assumed to have an input/output match of

1.5 VSWR.
