Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4957A #9165384 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4957A is a general-purpose electronic test (ET) equipment designed to measure electrical signals. It can measure a variety of features such as frequency, resistance, current, capacitance, and inductance. It includes an input and output connector for interfacing outside circuits as well as power supply and signal generators for driving and controlling the measurement systems. HP 4957A features a four-channel multiplexer allowing multiple electrical components to be measured at the same time. The four channels are independently adjustable and can be used to measure both linear and logarithmic characteristics of the signal. The multiplexer also allows the measurement of small signal waveforms with small differential delay between input and output signals. AGILENT 4957A is capable of standard measurements such as DC voltage, AC voltage, DC current, AC current, temperature, resistance, diode forward and reverse characteristics, and power factor. It also allows for frequency response measurements from a few Hertz to 1MHz and harmonic distortion measurements up to the third harmonic. The instrument offers a wide range of mathematical calculations that can be used to characterize input signals such as the RMS value, phase angle, maximum value, minimum value, and integration and differentiation functions. The user interface on HEWLETT-PACKARD 4957A consists of a LED display and ten key numerical keyboard. The LCD is useful for viewing and adjusting data and the ten key numerical keyboard can be used to enter measurement values. The interface allows operators to quickly adjust measurement parameters or select specialized functions. KEYSIGHT 4957A has several protection features including thermal protection and over-voltage/current limiting which helps to protect and extend the life of the unit. It is a low noise instrument and includes a variety of filters that can be used to remove unwanted noise from the output signal. 4957A is a versatile and reliable ETE instrument suitable for a variety of uses in the electronics industry. Its features and protection capabilities make it ideal for use in development and production applications.
