Product Description
The LibreVNA 100kHz - 6GHz USB Vector Network Analyzer is a cutting-edge, full 2-port VNA designed by Jankae, offering unparalleled precision and speed for RF testing and analysis. Utilizing 3 ADCs for simultaneous data sampling and FPGAs for advanced signal processing, this device can perform over 10,000 points of full dual-port measurements in less than 1 second. With an ultra-low noise power supply, 16-bit ADC, and precision CNC aluminum shielded housing, the LibreVNA achieves up to 100dB of effective dynamics, making it a powerful tool for professionals in the RF and microwave fields.
While the LibreVNA offers performance comparable to lab-grade VNAs, it is important to note that this is still a work-in-progress project. Performance may decrease at frequencies above 3GHz, and users should fully understand these limitations before purchasing. We welcome feedback and suggestions for future improvements.

Note 1:Due to structural limitations, S12 isolation is 10dB worse than S21. Above 3GHz, the performance decreases with increasing frequency, and the port isolation is only 50dB at 6GHz. Below 1MHz, the performance decreases with decreasing frequency, and the effective dynamic decreases to 70dB at 100kHz.
Note 2:The use of higher accuracy calibrators allows for higher precision measurements.
Note 3:The output power may decrease when the frequency is lower than 1MHz or higher than 3GHz.

									Thank you for visiting and shopping at BabyAmy.store. Below are the terms and conditions that constitute our shipping policy for BabyAmy.store sold products.
Shipment Processing Time
All orders are processed within 1-5 business days. During promotions or holidays, this may result in a delay in shipment. Customized items or wholesale orders will have their shipping time confirmed prior to order placement. If there is a significant delay in the shipment of your order, we will contact you via email or phone.
Shipping Service
Economy Shipping
Estimated delivery time is 30-60 days. It is shipped via Postal Small Parcel.
Standard Shipping
Estimated delivery time is 8-20 days. It is delivered via USPS, DPD, Sagawa, Correios, GLS, DHL eCommerce, and other couriers.
Expedited Shipping
Estimated delivery time is 5-15 days. It ships via DHL, UPS, FedEx, or ARAMEX. If you are located in a remote area, we charge an additional Remote Area Service Fee. Due to the high number of remote locations, this is not included in our shipping rates, so you will need to pay an additional $66 for the Remote Area Service Fee. Click this link to download the document to see if your country's zip code is within a remote area.
Sea or Rail Shipping
Our sea or rail transportation services offer economical solutions. Parcels are first shipped by sea and then cleared at the destination customs by a specialized customs clearance company (customs duties are included in the shipping cost). Please note that we provide the tracking number of the courier company in the destination country, so tracking information may not be updated during the initial ocean shipping period (usually 40-60 days). However, once the package is handed over to the local courier, tracking information will be updated. The local courier company typically completes delivery within 5-10 days.
Professional Shipping
Our professional transportation service provides a safe and fast solution. Parcels are first shipped by air and then cleared by a professional customs clearance company at the destination customs office (duties are included in the shipping cost). Please note that we provide the tracking number of the courier company in the destination country, so tracking information may not be updated during air shipment and customs clearance (usually 5-8 days). You can check the parcel's location via http://119.29.75.49:8082/trackIndex.htm. Once the package is handed over to the local courier company, tracking information will begin to update. The local courier typically completes delivery within 5-10 days.
Customs Duties or Value-Added Tax
When the chosen shipping service does not include a duty-free policy, the buyer is responsible for customs duties or VAT in their country. We usually assist by reducing the declared value of the merchandise on the package to minimize customs duties. For example, for an item valued at $300, we may reduce the declared value to around $100 (typically 20-30% of the actual value). As a result, the duty usually does not exceed 30% of the declared value, approximately $20-$30 USD, though this varies by country.
If you need customs clearance documents or invoices, please feel free to contact us. We will do our best to assist you in completing all necessary procedures smoothly.
Customs Clearance Procedures
If you choose Expedited Shipping, the recipient will usually be contacted by customs officers to provide necessary information for customs clearance. We strongly recommend actively cooperating with customs to ensure the parcel is cleared and delivered on time.
Please note that if the recipient refuses to cooperate with customs clearance procedures, the following consequences may occur:
- Parcel Return: Customs has the right to return the parcel to the place of dispatch. This will incur round-trip shipping costs and import customs duties, which may exceed the actual value of the merchandise.
- Destruction by Customs: If the recipient refuses to complete the formalities, Customs may destroy the parcel.
It is the recipient's responsibility to complete customs clearance procedures. To avoid unnecessary trouble and expense, please cooperate with customs and provide required information promptly. We are not responsible for consequences resulting from non-cooperation or refusal to complete customs clearance and cannot provide refunds or compensation in such cases.
Shipping Insurance
If your package is damaged in transit, it is important to draft a package damage report immediately. This report helps us and the shipping provider understand the incident details and process your claim promptly.
When submitting a parcel damage or loss report, please provide a detailed description of the incident and include relevant evidence, such as photos or videos. This information is critical for investigating and processing your claim.
You may submit your claim directly to the shipping provider or instruct us to file it on your behalf. Either way, we will do our best to resolve the issue and obtain appropriate compensation.
Note that Economy Shipping services typically do not include insurance. If you choose Economy Shipping, you bear all risks and losses in case of damage or loss.
Replacement or refund of your parcel will be processed only after the courier company investigates and confirms your claim. Submitting a damage report promptly and cooperating with the investigation are key steps in resolving the issue.
Shipment Confirmation and Order Tracking
After an order is shipped or processed, you will receive a shipment confirmation email with your tracking number. The tracking number will become active within 24-72 hours.
