Data Sheets

Specification (spec)

Specifications include guardbands to account for the expected statistical performance distribution, 

measurement uncertainties, and changes in performance due to environmental conditions. Specifications 

are warranted performance. FieldFox must be within its calibration cycle. No warm-up required for the spectrum 

analyzer specifications listed on pages 25 through 50.

Typical

Describes additional product performance information not covered by the product warranty. It is performance 

beyond specifications that 80% of the units exhibit with a 90% confidence level over the temperature range 

23 ± 5°C, unless otherwise noted. Typical performance does not include measurement uncertainty. FieldFox

must be within its calibration cycle.

Nominal

A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty. 

FieldFox must be within its calibration cycle.

Test port output specifications

High power in N991xA and N992xA refers to the target output power level of the analyzer when the Power 

Setting is set to High. As an example, if you have a frequency sweep from 3 to 6.5 GHz, the analyzer will achieve 

the power level of -1 dBm across the band.

Low power level for N991xA and N992xA analyzers is a flat -45 dBm across the whole frequency band and is the 

output of the analyzer when the Power Setting is set to Low.

High power in the N995xA refers to the target output power level of the analyzer when the Power Setting is set 

to High. As an example, if you have a frequency sweep from 39 to 46 GHz, the analyzer will achieve the power 

level of -2 dBm across the band.

Low power level for N995xA analyzers is the lowest power level that can be set and is the output of the analyzer 

when the Power Setting is set to Low.

Max leveled power in the N995xA refers to the maximum leveled (flattened) power that can be achieved across 

the designated frequency range. For example, if you have a frequency sweep from 32 to 44 GHz and set up the 

analyzer to measure all four S-parameters, needing both ports 1 and 2, the maximum power the analyzer can be

set to is -6 dBm.
