3.5 ACP Measurement

imperfect, the corrections are imperfect. Using NFE is very convenient; the user

need not wait for the ACP noise corrections calibration to occur. The ACP NC

calibration, though, has advantages of being measured very recently, at the current

ambient, and the exact center frequency, with no requirement that the model be

perfect. So, it will often (but not always) have slightly better dynamic range. If both

ACP NC is turned on and NFE is turned on, the instrument uses only the ACP NC.

When ACP NC is turned off, but NFE is on, NFE is used, and performance should still

be excellent.

When Meas Method is Fast Power, HW supported noise correction works when

either or both of Noise Correction and NFE is on.

Noise Floor Extension

Lets you configure Noise Floor Extension (NFE). All Modes that support NFE let you

set it on or off. Additionally, some Modes support two “on” states for NFE, Full and

Adaptive, as described below.

Adaptive Option Support

At present (Release: X-Apps 2024), support for Adaptive NFE is as follows:
