The Tektronix PSM4110 is a USB-connected RF power sensor delivering accurate measurements across 10 MHz to 8 GHz without requiring a separate mainframe. This PSM4000 series instrument characterizes average, peak, and pulse power signals with measurement uncertainty as low as 2.6% and dynamic range spanning -60 dBm to +20 dBm. Calibrated across its full operating temperature range, the sensor eliminates recalibration requirements and connects directly to a host computer via USB 2.0, providing plug-and-play operation with integrated Windows-based software for data logging and analysis.
