Description

Rohde & Schwarz ZNB8 Vector Network Analyzer Repair

The Rohde & Schwarz ZNB8 is a high-performance vector network analyzer covering up to 8.5 GHz — a 2- or 4-port benchtop VNA with wide dynamic range and fast sweep for measuring S-parameters on components, cables, and devices. As a precision microwave instrument, its faults concentrate in the source and receiver chains, the test-set/port hardware, and calibration stability.

June Company repairs and calibrates the R&S ZNB8 for RF/microwave engineering and component-test teams.

Common R&S ZNB8 problems we fix

Port or test-set damage — a damaged measurement port from overpower or connector wear degrading S-parameter accuracy, repaired.
Calibration won’t hold / fails — source, receiver, or directivity faults making cal unstable, tracked down and repaired.
Source or LO faults — no stimulus or unstable output, restored.
Receiver / mixer faults — low sensitivity or bad traces, repaired.
Display or interface faults.

FAQs

My ZNB8 cal won’t hold — fixable? Yes. Unstable cal usually points to the source, receiver, or a worn port; we repair the cause and verify stable S-parameter measurement, with a NIST-traceable certificate.

Is the test set serviceable? Yes — port and test-set repair is routine on ZNB analyzers.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. 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.
