Renew Your Device. Extend Its Value.
Let the value of your old device support your next upgrade
Eligible legacy spectrum analyzers are appraised and, once approved, receive a trade-in credit that goes toward the purchase of a new instrument. Trade-in is currently available toward the SA8T, SA12 and SA6000, so you can choose the model that best matches your measurement needs.
The program runs year-round, and newly released models will be added to the trade-in range over time.
Legacy portable spectrum analyzers, vector network analyzers, signal generators and SDR software-defined radios can be submitted. HTOOL units that are faulty or will not power on may also be submitted — send in the details first and our team will review them based on the model, overall completeness and the reported fault.
Portable spectrum analyzers from other brands that still work may be submitted for appraisal. Please contact our support team first to confirm which brands and models are eligible.
Missing the original box, or standard accessories that are incomplete, does not normally affect your application — the condition of the main unit is what gets assessed.
The trade-in credit is assessed against three factors:
Confirming the brand, model and identity of the device.
Checking power-on status, functional performance and overall completeness.
Confirming the trade-in arrangement that applies to your selected instrument.
Our team provides an estimated credit based on photos, videos and other materials, then confirms the final amount once the old unit arrives and has been inspected. If the unit matches the submitted materials, the pre-assessment result is normally applied; if there are differences, our team will explain the reason and confirm with you before proceeding.
Scan the WeChat support QR code on this page and tell us your old model and the new model you would like.
Provide photos of the front and back of the main unit, a photo of the serial number, and a power-on video or a description of the fault.
Review your eligibility, the estimated credit, shipping requirements and other details.
After the pre-assessment, pack the unit as instructed and mark the trade-in reference number.
We check the unit against your submission and confirm the final credit with you.
The new instrument is ordered and shipped under the arrangement you confirmed.
The program runs year-round. New models will be added over time; contact our support team for the currently eligible models and trade-in arrangements.
Designated HTOOL legacy units can be submitted for review; eligibility depends on the model, completeness and the fault. Devices from other brands must normally be in working order.
No. Trade-in requires returning the old device under the confirmed process and completing a physical inspection.
Our team will explain the difference and the reason for the adjustment. You may continue with the trade-in or cancel your application; return shipping and related arrangements follow the rules confirmed in advance.
New models will be added over time. Every application is reviewed again, and each device serial number can be used only once.
Have the brand, model and photos of your old device ready, then scan the code to reach HTOOL WeChat support for eligibility, an estimated credit and the exact procedure.
Once your old device is assessed, the new choice becomes clearer.
Please note: complete the pre-assessment before shipping your device. Eligibility and the final credit are subject to our support team's review and physical inspection. Before shipping, please confirm shipping costs, processing time, discount stacking, and how cancellation or returns of the new instrument are handled. For devices with a severely swollen battery or other shipping hazards, please contact our support team first.
Engineered to Fit Your Exact Requirements
Customization is available across the HTOOL product line
From product selection to the specifics of your application, we work with you to clarify requirements and evaluate a customization plan that fits, so the instrument serves your measurement tasks, project development and system integration as it should.
Whether your focus is performance specifications, functional configuration, mechanical design, system connectivity or the way the instrument is used, you can submit your requirements to HTOOL support. The exact scope, technical feasibility, cost and delivery schedule are confirmed against the product platform and your project requirements.
HTOOL customization covers spectrum analyzers, vector network analyzers, signal generators and SDR products, as well as antennas, probes and accessories.
You can request adjustments based on an existing model, or simply describe your application, target specifications and operating constraints, and our team will help route the request for evaluation. If you have not settled on a model yet, you can still get in touch.
Customization requests are accepted across the full product line; the projects that can actually be implemented are subject to the evaluation result and the plan confirmed by both parties.
Tell us the measurement parameters, functional configuration, operating method and practical goals you care about.
Share installation space, dimensions, connector layout, marking and appearance requirements.
Describe the equipment and software environment the product must work with, along with the connection method and data exchange requirements.
Let us know purchase quantity, accessory requirements, delivery time and acceptance criteria so a complete evaluation can be made.
The above are directions for discussion; the support actually available depends on the selected product and its technical conditions.
Contact our support team with the product model or application scenario, along with the goal you want to achieve.
We clarify the key specifications, operating conditions and project constraints, and assess feasibility.
Scope, technical requirements, pricing, quantity, delivery schedule and acceptance method are confirmed.
Work proceeds according to what both parties confirmed; if sample validation is involved, the arrangement is confirmed separately.
Delivery is completed as agreed, with usage and after-sales support provided within the confirmed service scope.
If you do not have complete technical documentation yet, start by describing your goal and the requirements can be refined step by step.
Customization requests are accepted for the entire HTOOL product line. The scope and implementation approach are confirmed according to the product platform and the evaluation.
You can submit the request first. Whether we can take it on, the minimum order quantity and any related costs are confirmed against the specific customization.
They depend on scope, technical complexity, validation requirements and quantity, and are confirmed with you once the requirement is clear.
Yes. We recommend completing the requirement discussion first, then reviewing feasibility, scope, pricing and delivery before confirming.
A single specification or a complete set of application requirements can both be the starting point.
Scan the WeChat support QR code on this page and contact HTOOL support for product customization
Note: the exact customization scope, technical specifications, cost, minimum order quantity, sample arrangements, lead time and after-sales terms are subject to what both parties finally confirm.
