The Keysight N4690A is a 2-port microwave electronic calibration (ECal) module, mainly used for the calibration of vector network analyzers. The following is an overview of its products:
Efficient and Accurate Calibration: It can make the calibration of vector network analyzers fast, simple and accurate. Compared with traditional mechanical calibration kits, the time and number of connections required for full two-port calibration are reduced by more than half, and the calibration accuracy is comparable to that of mechanical calibration methods. Traditional mechanical calibration requires a large amount of operator participation and is error-prone. When using the N4690A, the operator only needs to connect it to the network analyzer via a USB interface, and the rest of the work is controlled by software, reducing human errors.
Diverse Interface Modes: It has a USB interface and can be directly connected to and controlled by PNA and ENA series network analyzers. It can also be used with other analyzers such as Agilent 8753E/ES/ET or 8720D/ES/ET through the 85097B interface kit, but this requires a special parallel cable.
Good Performance Characteristics: It uses reliable solid-state switches and has an accurate calibration function traceable to the National Institute of Standards and Technology (NIST), ensuring the accuracy and reliability of calibration results. In addition, it can reduce the wear of connectors, extend the service life of test port connectors and calibration standards, and reduce maintenance costs.
