1. Base model means that the functionality listed is the primary function of that instrument. For example, on the N991xA or
N995xA combo analyzers, cable and antenna analysis is the standard function included with every N991xA or N995xA.

2. Option 305 is not available on the N993xA or N996xA. However, a subset of cable and antenna analyzer measurements, return
loss and VSWR, is available as Option 320.

3. Option 320 is not applicable to N991xA, N995xA, or N992xA. The reflection measurements of return loss and VSWR are
included with every N991xA, N995xA, and N992xA. So, there is no need for an Option 320 on these analyzers.

4. On the N991xA or N995xA analyzers, order Options 233 and 210 to obtain a tracking generator with the spectrum analyzer.
Option 220 is not available on the N991xA or N995xA analyzers. Option 233 provides the spectrum analyzer capability and
Option 210 the “tracking” capability.

N9910HU-400 N9918/28/38A processor upgrade

1. Upgrades are not available for FieldFox analyzers with serial number prefix starting MY5607/SG5607/US5607, as these

analyzers already have the improved hardware.

2. Please contact your local Keysight Service Center for instructions on how and where to send the instrument and how to order

the factory upgrades.
