The Agilent/HP 53132A is a 3 GHz universal frequency counter delivering high-resolution measurements across RF, microwave, and electronic development applications. It measures frequency, period, ratio, time interval, pulse width, rise/fall time, phase angle, duty cycle, and peak voltage with 12-digit resolution and 150 picosecond time interval accuracy. The instrument executes up to 200 measurements per second and includes built-in statistics (min, max, average, standard deviation), math functions, and automated limit testing with visual and signal output indicators.
