Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4431B #9167574 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4431B is an advanced digital signal generator used for precise test and measurement of frequency response, modulation, distortion, noise and a variety of other parameters. With a frequency range of 9 kHz to 3 GHz, HP E4431B provides both single tone output and multi-tone output capability as well as the ability to generate both analog and digitally modulated signals. AGILENT E4431B is well-suited to both general-purpose measurements and specific tests such as evaluating wireless communication signals. The unit features a color LCD display that provides clear waveform and modulation visualization, and an integrated signal conditioning and control system which allows the user precise control over frequency, amplitude, modulation, pulse and signal shape settings. While the unit can be operated manually, an optional GPIB interface is available to fully automate signal generation by allowing remote control from a PC or other device. HEWLETT-PACKARD E4431B's three RF outputs can be combined to generate a wide range of signal patterns, such as multi-carrier waveforms, double sideband signals and multi-tone signals. The built-in signal conditioning system can also be used to quickly adjust amplitude and other parameters for fast signal optimization. The unit is compatible with GPS, CDMA, TDMA, and WCDMA standards, allowing it to be used to test current wireless devices. In terms of system performance, KEYSIGHT E4431B provides excellent harmonic distortion (HD3 -65 dBc) and spurious free dynamic range (SFDR) (80 dBc) to allow precise signal characterization. Low phase noise (1 Hz offsets from the carrier as low as -85 dBc/Hz) ensures minimal signal drift and prevents unwanted spectral regrowth, allowing the user to make more accurate measurements. E4431B also offers a wide range of modulation capabilities, including AM, FM and VSB. Additionally, the unit comes with an internal AM/FM modulator and digital burst modulator, allowing users to easily generate digitally modulated signals. Overall, AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4431B is a versatile electronic test equipment that packs a great combination of features into a flexible, feature-rich design. It provides excellent performance while allowing for quick and easy automated signal generation and optimization.
