Description

Keysight N5191A Signal Generator Repair

The Keysight N5191A 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.

Certified technicians at June Company service the Keysight N5191A Signal Generator 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.

Common Keysight N5191A Signal Generator problems we fix

Modulation not applying correctly.
Output attenuator relay faults.
Harmonic or spurious performance degraded.
Cooling fan or thermal shutdown.
Internal power supply faults.
GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
Display, keypad or front-panel faults.
Output level inaccurate or not levelling – the attenuator and levelling loop, which drift together and are verified across the full output range.
Frequency accuracy or reference drift.
