Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT EPM-442A #179117 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT EPM-442A is a four-channel, dual-channel and single-channel electronic test and measurement instrument, designed for high-performance measurements with low distortion and high accuracy. The tested signal levels can be as high as +20V/-20V DC and as low as 0.1µV AC into a 50-Ω load. This makes it suitable for accurate research as well as production applications. The four channels on HP EPM-442A provide both single-ended and differential inputs, allowing for the simultaneous measurement of two independent signals. It also provides programmable DC offsets and gains, as well as optional tracking filters. There is also a wide frequency range, up to 33MHz, so it can be used for a broad range of applications. The accuracy is also very high, with a total harmonic distortion of <0.02%. In terms of control, AGILENT EPM-442A offers a range of options. It is possible to control the instrument via RS232 or GPIB, with both local and remote operation as well as automated testing through the use of macros. There is also a built-in Parameter Analyzer for analyzing the common parameters of the signals such as frequency, duty cycle, peak-to-peak values, and more. This can be done with stored parameters such as frequency, duty cycle, peak-to-peak values, and more. EPM-442A also offers a range of safety features. It comes with reverse-polarity protection and isolation between the channels, making it suitable for laboratory use. The instrument is also compliant with a variety of regulations such as ISO 14598, RTCA/DO-160, IEC 61010, FCC, UL, and CE. In conclusion, HEWLETT-PACKARD EPM-442A is a versatile and reliable electronic test and measurement instrument that can be used for a wide range of applications. It provides high accuracy as well as safety features, allowing for reliable readings even in the most demanding of environments. It is also programmable via an intuitive interface and provides automated testing options, making it suitable for both researchers and production applications.
