Description

Keysight N9343C Spectrum Analyzer Repair and Calibration

The Keysight N9343C Spectrum Analyzer is a spectrum analyzer – it sweeps across frequency and reports amplitude, which means its input attenuator sits directly in the signal path and takes the consequences of anything connected to it. Over-power damage there is the commonest serious fault on these instruments.

The Keysight N9343C Spectrum Analyzer is repaired at June Company by technicians who work on this class of instrument daily, for RF engineers, EMC laboratories, communications technicians, and manufacturing test teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common Keysight N9343C Spectrum Analyzer problems we fix

Display, keypad or front-panel faults.
Input attenuator damaged by over-power – the front-end taking a signal beyond its damage level, which leaves amplitude readings wrong across the board rather than obviously broken.
Amplitude accuracy or flatness out of specification.
YIG tuned filter or oscillator faults.
Phase noise degraded.
Preamplifier or mixer failure.
Reference oscillator drift.
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.

FAQs

Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.

Amplitude reads low across the whole span. What causes that? Usually input attenuator damage from an over-power event. It shifts everything rather than breaking anything obviously.

Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.

We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
