The Agilent HP 5386A Frequency Counter offers prescaled measurements to 3 GHz based on gallium arsenide (GaAs) technology. The GaAs prescaler and attenuator circuitry are integrated on a hybrid substrate. Bipolar technology permits the integration of reciprocal counting and interpolation techniques on a single integrated circuit. The tightly-integrated design achieves overall high performance, excellent reliability, and low cost of ownership. The Agilent HP 5386A incorporates a 12-character display, accessible remotely via HP-IB. The liquid crystal display (LCD) can be read in direct sunlight, and has large characters that can be seen from the end of a bench or mounted high in a test rack. The 5386A can be easily carried to remote locations for service and calibration applications. * Measurements displayed in meaningful units * Reduced switching requirements * Measurements to 3 GHz with -23.5 dBm sensitivity, a 30.5 dB dynamic range, and a damage level of +25 dBm * Half-rack width saves rack space * Optional high-stability ovenized oscillator offers greater accuracy * Measurements Displayed * Controlled via HP-IB, the display can be used for messages and operator prompts, or even blanked for security. * Measurements are displayed in your choice of units. The number of digits displayed can be varied from the front panel or HP-IB. * Reduced Switching * Frequency measurements from 10 Hz to 3 GHz are made with two input ports, instead of three, for reduced switching. |
