Buy Used RF Equipment — Refurbished & Tested, Shipped in Europe

RF-Labs stocks pre-owned RF test equipment from Keysight, Rohde & Schwarz, Agilent, Anritsu, and HP — tested, verified, and shipped from within the EU. Every unit goes through functional inspection and performance checks before it reaches your bench. As a result, there are no transatlantic customs delays and no surprise import duties.

Whether you need a vector network analyzer for production testing, a spectrum analyzer for EMC pre-compliance, or a signal generator for R&D, buying refurbished saves 40–70% over new list price. That margin, in turn, matters when equipping a lab or scaling a test line.

Why Buy Used RF Equipment From a European Supplier?

Most used RF equipment listed online ships from US-based resellers. That creates three problems for European buyers: customs clearance, unpredictable lead times, and calibration certificates that may not meet EU laboratory accreditation requirements. RF-Labs, however, eliminates all three.

• 40–70% below new list price. A Rohde & Schwarz SMA100A signal generator or an Agilent 8720ES network analyzer, for example, sells at a fraction of OEM pricing — with verified performance.
• No customs, no import VAT surprises. Intra-EU shipments move freely, and UK buyers get DDP options with Brexit import handled on our side.
• EU-compliant calibration. ISO 17025 accredited calibration is available with 5-day turnaround at our facility — not a generic “certificate of conformance,” but traceable, accredited documentation.
• Warranty and returns. Every unit sold includes a functional warranty. Compare that to most US resellers, which typically offer 5–14 day return windows with restocking fees and return shipping at the buyer’s cost across the Atlantic.

New vs. Refurbished vs. US Reseller: Cost Comparison

Here is how the options compare side by side:

• Buy new from OEM: Full list price (€20,000–€80,000+ for mid-range instruments). Lead time 6–16 weeks. Full OEM warranty and calibration.
• Buy refurbished from RF-Labs (EU): 40–70% savings. Delivery in 2–5 business days across EU/EEA/UK. Functional warranty included. ISO 17025 calibration available. No customs paperwork.
• Buy from US reseller: Similar savings to refurbished EU, but shipping takes 10–18 business days. Customs clearance applies, and the buyer covers import VAT plus potential duties on arrival. Calibration may not carry EU-accredited traceability, and returns are expensive and slow.

The price gap between an EU and US reseller is often negligible. Once you factor in customs brokerage, duty risk, and recalibration, therefore, total cost of ownership tips clearly toward buying within the single market.

Brands We Stock

RF-Labs focuses on the OEMs that dominate European test labs. Our technicians, as a result, know these platforms — what to check, which options to verify, and where common failure points appear with age.

• Keysight / Agilent — Current Keysight models (N5172B EXG, 34410A, 34970A, N8990 switch boxes) alongside legacy Agilent instruments (8720ES, 8753ES, E8357A, E8358A, E4421). The Agilent-to-Keysight rebrand, in fact, left thousands of perfectly functional units on the secondary market — same hardware, lower price. Browse Keysight / Agilent inventory.
• Rohde & Schwarz — Signal generators (SMA100A, SMBV100A in multiple frequency variants, SMU200A, SMIQ 03B), the FSP spectrum analyzer, and NRP-Z11 power sensors. Long service life and strong residual value, therefore, make these particularly good candidates for second-hand purchase. See available Rohde & Schwarz units.
• HP — Classic Hewlett-Packard instruments including the 6622A and 6674A power supplies. Many of these units were built for 20+ years of continuous rack operation, and still meet original specifications today. HP & other OEM equipment.

Our Refurbishment & Quality Process

Every unit entering RF-Labs inventory goes through a structured inspection sequence — not a visual check and a wipe-down, but a multi-stage process designed to confirm the instrument performs to OEM specifications.

• Incoming inspection: Visual and mechanical check for damage, missing hardware, connector wear, and display condition.
• Functional verification: Power-on test, self-test pass, key parameter verification against the manufacturer’s published specifications. For network analyzers, this includes port match and dynamic range checks; for signal generators, output level accuracy and phase noise spot checks.
• Calibration options: Basic functional check included with every sale. Full ISO 17025 accredited calibration is also available, with 5-day turnaround. The resulting certificate, moreover, is traceable and accepted by EU accreditation bodies.
• Cosmetic grading: Grade A (near-new appearance, minimal marks), Grade B (normal signs of professional use, fully functional), Grade C (visible wear, cosmetic imperfections, full electrical performance). Every listing states the grade clearly.
• Firmware and options: Installed firmware version confirmed. We verify and document licensed option keys — in other words, no grey-area option activations.

Our refurbishment and certification process page, meanwhile, documents full details on each step.

How to Buy — Process & Shipping

Purchasing from RF-Labs works the way procurement departments expect. In other words, no marketplace friction and no consumer-grade checkout flow.

• Browse or request. Check current stock on the site. If a specific model or option configuration is not listed, submit a wanted request instead — we source instruments continuously from labs and OEM trade-in programs across Europe.
• Quotation and payment. We issue formal quotes with equipment details, condition grade, calibration status, and pricing in EUR. We accept payment by bank transfer or company purchase order. EU VAT invoicing is standard, and the reverse-charge mechanism applies for intra-EU B2B transactions where applicable.
• Shipping. DHL and FedEx express across the EU, EEA, and UK. Typical delivery: 2–5 business days. US-based resellers, by comparison, average 10–18 business days to a European destination, plus customs processing.
• UK buyers. We handle post-Brexit shipments with DDP (Delivered Duty Paid) options available. As a result, there are no clearance delays and no surprise duty invoices from the carrier weeks later.

Frequently Asked Questions

Is used RF test equipment reliable?

Keysight, Rohde & Schwarz, and Agilent engineer professional-grade instruments for 15–25+ year operational lifespans. An Agilent 8753ES network analyzer manufactured in 2004, for instance, can still meet its published specifications when properly maintained. The critical factor is verification before sale — which is why every RF-Labs unit is tested against OEM specs before shipment.

What warranty do I get?

Every unit ships with a functional warranty covering defects and out-of-spec performance. Warranty duration depends on the instrument category and is stated explicitly in the quotation. In short, this is not an “as-is” marketplace transaction.

Can I get a specific option key or frequency extension?

In many cases, yes. Some option keys can be purchased from the OEM and installed on a pre-owned instrument — for example, bandwidth upgrades on Keysight EXG generators or additional measurement personalities on R&S signal analyzers. Other options, however, are hardware-dependent. Contact us with the model and desired option before committing; we will then confirm feasibility and pricing.

Do you buy back equipment?

RF-Labs purchases surplus and end-of-life RF test equipment from labs, manufacturers, and service providers across Europe. If you have instruments to sell or want to trade in against a purchase, therefore, contact us with model details and approximate condition.
