Field-use instruments check phone base stations

Article Abstract:

Kikusui Electronics Corp.'s CPM20 and CPM46 multiple-function measuring devices are used for constructing and maintaining mobile phone base stations as well as commercial microwave stations. The lightweight instruments integrate a microwave frequency counter, a power meter and a digital DC voltmeter for determining automatic gain control voltage. The CPM20, which is priced at $10,423, works at 10 to 20 GHz, whereas the $13,944-worth CPM46 device functions at 10 to 46 GHz. Another feature is the reference oscillator that does not need pre-heating, thus enhancing efficiency and lessens battery consumption.
