Coaxial Power Detector
Product Introduction
Coaxial Power Detector is designed to address the demand for real-time, accurate, and stable power measurement of coaxial-transmitted RF/microwave signals. Unlike general-purpose power meters, this detector integrates a high-sensitivity power-sensing module, a coaxial interface adapter, and a digital signal processing unit, enabling direct connection to coaxial transmission lines without additional conversion compon ents. It supports both continuous-wave (CW) and pulsed signal measurement, with frequency ranges typically covering DC to 67GHz and power measurement ranges from -60dBm to +20dBm, meeting the testing needs of low-power signal monitoring and high-power signal detection. The device is available in three main types: benchtop precision type, handheld portable type, and rack-mounted integrated type, adapting to diverse application scenarios.

FAQ
Q: What is the difference between Coaxial Power Detector and a general RF power meter?
A: A general RF power meter usually requires an external power sensor and connecting cables, which may introduce additional insertion loss and measurement errors. Coaxial Power Detector integrates a dedicated coaxial power sensor and interface, enabling direct connection to coaxial lines without extra components—this reduces loss, improves accuracy, and simplifies operation, making it more suitable for scenario-specific coaxial system testing.
Q: How often does Coaxial Power Detector need to be recalibrated?
A: The calibration interval depends on the usage frequency and environment: Benchtop precision models require recalibration every 6 months; Handheld and rack-mounted models can be recalibrated every 12 months. If the device is exposed to severe impact, high humidity, or extreme temperatures, it is recommended to shorten the interval and conduct a pre-use verification with a standard signal source.
