Feedthrough Power Standard 10 MHz to 26.5 GHz The TEGAM F1135B Temperature Controlled Coaxial RF Power Transfer Standard enables the precise measurement of microwave power in the 10 MHz to 26.5 GHz frequency range. These units are extremely rugged, highly accurate, and stable with time and temperature. They are ideal for use as standards for the transfer of calibration factors to RF power sensors. Units are supplied with A2LA Accredited ISO/IEC 17025 Compliant Calibration. These models are designed for use with DC self-balancing bridges such as the TEGAM Model 1806B and 1804 or the 1830A which is Direct Reading Thermistor Power Meter. The Model F1135B is a feedthrough Thermistor Standard and Power Splitter combination used for the calibration of thermistor, thermocouple, and diode power sensors. Technical Specifications Used to calibrate RF Power Sensors in the 10 MHz to 26.5 GHz frequency range Standards are directly traceable to NIST Thermistor Standards are temperature controlled A2LA Accredited ISO/IEC 17025 Compliant Calibration Included NSN: 6625-01-536-3693 3 year warranty Made in USA
