M1135A Terminating Power Standard

Brand: Tegam

The TEGAM M1135A 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 wherever an accurate RF power measurement is required.

The Model M1135A is a terminating thermistor Reference Standard.

It is designed to be calibrated directly by a national standards agency such as NIST.

The M1135A is used for the calibration of feedthrough devices such as bolometer mount-coupler and bolometer mount-splitter RF standards.

It is also used in other applications requiring direct measurement of RF power.
