New IEEE Standard – Inactive – Withdrawn. Withdrawn Standard. Withdrawn Date: Dec 06, 1990. This standard applies to bolometric power meters as complete instruments and to their constituent parts: bolometric detectors, bolometer units, and bolometer elements. Bolometer power measurement instrumentation is generally used to measure, below 100 mW and above 10 MHz, the average power of electromagnetic waves propogating in a single mode in waveguide or coaxial transmission lines. The power range can be extended by the use of attenuators or directional couplers, or both.<\/p>\n
