IEEE 287 Laboratory Grade coaxial connectors and interconnects are similar to precision grade connectors but with even tighter tolerances and performance specifications. They are designed for use in laboratory and testing environments, where accuracy and precision are of utmost importance. These connectors are typically used in high-precision test equipment, instrumentation, and other applications that require the highest level of performance and accuracy. Below are some of the ways Laboratory Grade connectors compare to Precision and Standard grade components.
- Maximum Operating Frequency: The maximum operating frequency of a Laboratory Grade connector is typically higher than that of a Precision Grade connector and significantly higher than that of a Standard Grade connector. For example, a Laboratory Grade SMA connector might have a maximum operating frequency of 40 GHz, while a Precision Grade SMA connector might have a maximum operating frequency of 18 GHz and a Standard Grade SMA connector might have a maximum operating frequency of 4 GHz.
- Tolerances: Laboratory Grade connectors have the tightest tolerances of any type of coaxial connector, ensuring that the physical dimensions and electrical specifications of the connectors are held to the highest standards. For example, Laboratory Grade connectors might have tighter specifications for connector impedance, insertion loss, and return loss compared to Precision Grade or Standard Grade connectors.
- Durability: Laboratory Grade connectors are typically designed to be highly durable and reliable, as they are intended for use in demanding laboratory and testing environments where consistent performance is critical.
