The Keysight 44465A is a 6.5-digit benchtop digital multimeter built on Truevolt technology, delivering precision measurement across voltage, current, resistance, frequency, capacitance, and temperature with acquisition rates to 50,000 readings/second. Its 4.3-inch color graphical display supports real-time trend analysis, histograms, and bar charts, while patented analog-to-digital conversion eliminates noise and injected current errors. The instrument captures transient events in digitizing mode and performs low-µA current measurements with picoampere resolution—ideal for power-conscious device characterization.
