Full Bypass Path for X-Series Signal Analyzers

Application Notes

1. Overview of Full Bypass Path

The Full Bypass Path (FBP) is available for UXA and PXA Series Signal Analyzers (N9040B, N9041B, N9042B, N9030B). FBP combines the Low-Noise Path (LNP) and Microwave Preselector Bypass (MPB) to improve error vector magnitude (EVM) performance when measuring wideband signals in the power range of –15 to +20 dBm by lowering signal path loss thus improving sensitivity. Full Bypass is not available on the MXA Signal Analyzer (N9020B), since it does not have a low noise path to be able to bypass the low band switch. The Full Bypass Path was first introduced on N9040Bs with option H1G and then was made available on N9041Bs with H1G. More recently in 2020, the Full Bypass Path was made available on all UXA and PXAs with wideband digitizer options B2X or B5X and that have options LNP and MPB. In the year 2021, N9042B launched with the FBP option as standard. Options LNP and MPB are standard on UXA and are optional on PXA.
