Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 438A #9103888 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 438A is an analog voltage and current source measurement equipment designed for signal characterization and debugging of electronic designs. HP 438A provides high accuracy performance with dc, AC, pulse, and resistance measurements. AGILENT 438A is a single box instrument that combines the functions of a signal generator and a volume-operated preamplifier with a precision measurement engine. It delivers a wide range of output levels, from 1 mV to 10 V in 0.1 mV steps, with high resolution and stability. The system includes two primary units - the mainframe and a power module. The mainframe contains the amplifier, a built-in signal generator, attenuator, local oscillator, trigger circuit, waveform generation, digital-to-analog converters (DACs), and digital I/O circuits. All of these features facilitate the use of the unit with any voltage and current source, including AC, DC, and pulse sources. The power module allows users to control output voltage and current levels directly from the mainframe. On the top of the power module, users can control four output levels in either AC or DC mode. The power module also permits the user to select from four voltage ranges up to 10V, and either AC or DC operation. 438A machine is designed with user-friendly controls and interfaces. Its control panel is easy to access and provides an intuitive representation of the signal path. Its PC interface facilitates connection to a PC for remote data acquisition. The tool has enhanced safety features to protect against overloading, as well as extensive measurement accuracy assurance. Overall, HEWLETT-PACKARD 438A is a reliable and well-built apparatus for characterizing and debugging electronic designs. Its advanced features are cost-effective and offer flexible operation and measurement options. Thanks to its precise measurement capabilities and intuitive user interface, it is an excellent choice for any type of electronic design, testing, and measurement.
