Agilent's FieldFox RF vector network analyzer is the world’s most accurate handheld VNA. Key differentiators include:

• Built-in QuickCal technology enables calibration without a cal kit
• Best measurement stability over time and temperature
• Industry´s only handheld network analyzer with MIL PRF 28800F Class 2 compliance with no exceptions

A standard FieldFox RF VNA provides T/R measurements, or S11 and S21, with magnitude and phase. Adding Option 122 (full 2-port S-parameters) brings new levels of accuracy and convenience for testing RF components, and allows measurement of all 4 S-parameters at the same time.

Using FieldFox´s vector voltmeter (VVM), similar to the 8508A, the phase shift and electrical length of a device can be measured. The VVM option also provides ratio measurements of two channels, A/B or B/A.

FieldFox´s other application include distance-to-fault and VSWR testing, absolute power measurements, and characterization of 75-ohm cable TV devices.
