FAQs

How is the Spectrum Core J0SSAM31 controlled?

The reviewed product data indicates that the device is controlled via a virtual COM port using a USB interface. It features an open API for direct access to measurement functions, allowing for OS-agnostic integration with custom software.

Can this device be used to measure RF field strength?

In general, a spectrum analyzer can be used to measure RF field strength or power density when connected to a receiving antenna via coaxial cable. This process typically involves accounting for antenna factor, cable loss, and other system variables to convert the measured power (in dBm) to field strength (in V/m) or power density (in W/m²). For specific procedures and conversion formulas, consulting technical references on electromagnetic field measurements is recommended. The reviewed product data for the J0SSAM31 does not list an included antenna or specific field strength measurement software.
