Description

Keysight N5166B Vector Signal Generator Repair

The Keysight N5166B Vector Signal Generator is a signal generator – it produces a signal of known frequency, level and modulation, which means its output attenuator and levelling loop carry the accuracy of everything it is used to test.

The Keysight N5166B Vector Signal Generator is repaired at June Company by technicians who work on this class of instrument daily, for RF engineers, communications test teams, EMC laboratories, and manufacturing test departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
