A miniature RF and microwave power meter that extends the frequency limit for available USB power meters up to 26.5GHz has been released by Satori Technology Ltd. The ST265 covers a frequency range of 10MHz to 26.5GHz.

All measurement data and settings are sent via a USB interface to and from a PC or laptop. This gives the experience of using a computer as the user interface in classic microwave power measurement. Each power meters contains a CPU, which controls the sensor, processes the measurement results and operates the USB interface.

Improved features
The ST265 extends the company's existing ST124 and ST185 lines of USB power meters. Extended individual calibration procedures have resulted in improved temperature compensation and better linearity performance with RF frequency. The use of a K-type RF connector gives repeatedly low reflection coefficients up to 26.5GHz.

Satori Technology supplies its own software toolkit, which enables multiple power meters to be operated simultaneously. Drivers are available for Agilent VEE and National Instruments LabVIEW. Measuring 34mm x 43mm x 125mm, the meters weigh 83g.
