Precision 7 mm Connectors

Performance Test

Except for Option 13, the 281B model adapter has a APC-7 precision 7-mm coaxial connector. These connectors rely on uniform end-to end contact of both conductors for electrical continuity. Consequently, the condition of the contacting surfaces is critical: they should be kept clean and smooth. To prevent damage when the adapter is not in use, the connector’s threaded sleeve should be fully extended.

The maximum SWR for the Adapters are listed in Table 1. When making these measurements, the test results must be less than those listed in Table 1 plus the measurement uncertainty of the measurement system. Measurement may be made using a standard reflectometer setup. To ensure satisfactory performance, make sure flanges and coaxial connectors are not damaged or worn.
