   The Model 81001-A Wattmeter, identical to the Model 821-A, has the added feature of an A/B switchable DC input, providing the option of single meter measurement of several power sources. Line sections are permanently installed at these measurement points, with Model 81001-A connected to each as needed (10 foot cable is normally supplied). The DC signal is coupled from the line section to the switchable DC input to provide the same measuring capabilities as the basic Model 821-A. The Model 81001-A Wattmeter ... now you can measure RF Power in 50-Ohm coaxial cable and transmission lines, and accept plug-in elements in the range of 100 mW to 10 kW full scale, and from 0.45 to 2300 MHz. Complete with a built-in line section, our Quick Match RF connectors for 50-Ohm cables and transmission lines offer the speed and reliability you expect from Coaxial Dynamics. The 81001-A is easy to use. Simply connect the Wattmeter between the power source and antenna or dummy load, plug in the appropriate measuring element and select forward or reflected direction. The RF power is directly displayed on the 4-1/2" triple scale meter. Versatile and strong, the Model 81001-A can be used with accessory cables up to 200 feet from the meter and is protected by a rugged, virtually indestructible shock-proof housing. For added convenience, two sockets for storage of additional elements are located on the back of the unit. The use of a rugged shock mounted meter with a mirror-backed scale along with superior taut band technology, provides reliable and accurate readings, and also satisfies both the US Navy and Canadian standards for bounce and vibration. This is your assurance of complete accuracy. Your confidence in the quality and dependability of the Model 81001-A Wattmeter is assured with the Coaxial Dynamics Two Year Limited Warranty.
