FieldFox Handheld Analyzers

FieldFox Handheld Analyzers

This data sheet provides the specified and typical performance of the FieldFox family of portable analyzers. This data sheet should be used in conjunction with the technical overviews and configuration guide, for a complete description of the analyzers. The specifications for the 32, 44, or 50 GHz analyzers shown in this data sheet apply to the FieldFox analyzers with Serial Number prefix break ≥ MY/US/SG6125, or with the RF board Part Number: N9960- 630111. If your FieldFox analyzer (32, 44, or 50 GHz) is with the older RF board (Part Number of N9960- 630011) and desire to obtain a copy of data sheet that includes specifications reflecting the previous version of hardware, you may contact Keysight technical support by creating a support case via https://support.keysight.com/s/. The specifications and measurement capabilities listed in this document require certain options on the FieldFox analyzer. Refer to the FieldFox Configuration Guide to obtain option information. The configuration guide is the main resource for option/measurement capability information (https://www.keysight.com/us/en/assets/7018-06515/configuration-guides/5992-3701.pdf).

Definitions

Specification (spec)

Specifications include guard bands 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 specifications listed on pages 40 through 96.

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.

Cable and Antenna Analyzer and Vector Network Analyzer

he performance listed in this section applies to the cable and antenna analyzer (referred to as CAT) and vector network analyzer (VNA) capabilities available in the following models: FieldFox RF & microwave (combination) analyzers: N9913B, N9914B, N9915B, N9916B, N9917B, N9918B, N9950B, N9951B, N9952B, N9953B NOTE: Combination analyzers = Cable and antenna tester (CAT) + Vector network analyzer (VNA) + Spectrum analyzer (SA)

Cable and Antenna Analyzer and Vector Network Analyzer (continued) Test port output specifications.

High power in the N991xB and N995xB refers to the analyzer’s target output power level when the Power Setting is High. Examples:

• N991xB: For a 5 to 10 GHz frequency sweep, the analyzer achieves a 7 dBm power level across the band.
• N995xB: For an 18 to 26.5 GHz frequency sweep, the analyzer achieves a 4 dBm power level across the band.

Low power level for N991xB and N995xB analyzers flattens at -50 dBm across the entire frequency band and is the analyzer’s output when the Power Setting is Low.

Max leveled power in the N991xB and N995xB refers to the maximum leveled (flattened) power achieved across the designated frequency range. Examples:

• N991xB: For a 1 to 10 GHz frequency sweep with the analyzer configured to measure all four S-parameters, needing both ports 1 and 2, the maximum power the analyzer can be set to is 5 dBm.
• N995xB: For an 18 to 26.5 GHz frequency sweep with the analyzer configured to measure all four S-parameters, needing both ports 1 and 2, the maximum power the analyzer can be set to is 3 dBm.

CAT and VNA mode Calibrations

FieldFox analyzers offer three tiers of calibrations, thus providing users with different levels of calibration effort and accuracy.

CalReady

CalReady is the most basic calibration and is sufficient for a quick pass/fail or go/no go verification. Every FieldFox is calibrated at the factory, at test ports 1 and 2, at room temperature. CalReady can be applied either as an “enhanced response CalReady” or a “2-port CalReady.” The default setting is 2-port CalReady, so correction is applied to both ports. A user preference allows user to change the CalReady methodology to enhanced response CalReady. A 30-minute warm-up period is recommended for a quick test. A 60-minute warm-up is necessary for more stringent test requirements. If CalReady is the basis for most measurements, the annual cal cycle must be followed, as the CalReady calibration will be updated during the annual cal cycle.

Standard calibrations

Standard calibrations are the most accurate calibrations offered in FieldFox. FieldFox’s calibration engine is based on Keysight’s flagship PNA calibration engine, and as such, offers many of the standard calibrations. FieldFox supports both coaxial and waveguide calibrations. The table below lists the commonly used calibrations. Keysight recommends a 30-minute warm-up period for standard calibrations. For ultimate in stability and accuracy, a 90-minute warm-up period is necessary.

ECal

FieldFox supports all Keysight USB ECal modules, both standard and value-line ECals.

FieldFox’s Guided Calibration Wizard

FieldFox’s calibration wizard recommends a calibration type and calibration kit based on selected parameters and connector types. Alternatively, users can select their own calibration type and calibration kit. FieldFox’s calibration wizard ensures a valid calibration selection.
