N9912CU-308

N9912CU-308 is a vector voltmeter option. Measure a device's phase shift and electrical length and view the results on the large display from a distance. VVM also provides ratio measurements of magnitude and phase of two channels, A/B or B/A. You can use this capability to verify the magnitude and phase differences between multiple signal paths such as in an antenna or phased array.

• Similar functionality to the HP 8508A VVM
• Source and directional coupler are inside the FieldFox
• Requires options 210 and 211 for full VVM functionality
