       Refers to the measurement capability being available in the analyzer; either as standard or optional. Refer to the product’s Configuration Guide for option information.

1. N995xA and N996xA are significantly faster than N991xA and N992xA. In most frequency ranges, the N995xA and N996xA models also have the highest dynamic range and best DANL. Measurement accuracy is comparable between the models. The Data Sheet should be used for a more detailed specification comparison.
2. N993xA and N996xA (spectrum analyzer only models) offer the ability to measure VSWR/reflection (as an option), but not the full cable and antenna analyzer features.
3. N9912A offers S11 magnitude and phase and S21 magnitude. There is no S21 phase. Calibration choices: OSL, response and QuickCal.
4. N9912A’s QuickCal is a subset of the QuickCal available on other FieldFox models.
5. QuickCal is not available on N9950A, N9951A, and N9952A.
6. N9912A’s VVM includes a subset of the features: 1-port cable trimming mag and phase, and 2-port transmission magnitude. The full VVM (available on other models) includes 1-port cable trimming mag and phase, 2-port transmission mag and phase, A/B and B/A.
7. FieldFox’s interference analyzer capability includes spectrogram, waterfall, and trace playback and recording.
8. ERTA: Extended range transmission analysis. ERTA enables scalar transmission measurement of long-cables using two FieldFoxes.
9. N9912A and N9923A can display GPS information using an external USB GPS receiver which the user needs to purchase separately. All other FieldFox models have a built-in GPS receiver, available as option 307. The user will need to purchase a GPS antenna N9910X-825.
10. SCPI over USB is only available on N995xA and N996xA models; it is not available on N991xA, N992xA, and N993xA analyzer.
