Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4405B #156940 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E4405B is a spectrum analyzer designed for testing and measuring signals in the frequency ranges of 9kHz to 7GHz. The instrument performs frequency measurements, displays a spectrum and rapidly characterizes signals. It also has an optimized receiver that offers low distortion, noise, and interference immunity. HP E4405B has a resolution bandwidth of at least 1MHz and dynamic range up to 121dB. It also has an amplitude stability of approximately 1 part in 1000 of the span over the temperature range of -20 to +50°C and has a maximum input power at 16dBm. AGILENT E 4405B supports many measurement functions that can be useful when analyzing radio and wireless products, including time gated spectrum, digital modulation, power and mark measurements, channel power monitoring and channel scan. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT E 4405B also features an internal preamp which can increase wide range maximum power levels from 16dBm to +31dBm when the preamp is installed. It provides excellent sensitivity and noise floor performance for measurements of very low power signals including digital communications, cable TV and wireless signals. KEYSIGHT E4405B also has a 20dB attenuator which can be used to reduce the input signal power. This feature is useful when measuring large amplitude signals that may be too powerful and cause overload in the analyzer. In addition, HEWLETT-PACKARD E4405B has a built-in frequency offset function which allows the operator to set the center frequency as if the analyzer is tracking to a master reference. HEWLETT-PACKARD E 4405B also offers multi-domain measurements, which allow the user to simultaneously measure multiple frequency bands with the same settings. This feature can be useful for measuring radio signals that have multiple carriers, such as those used for cellular and GPS. E 4405B is a powerful, yet easy-to-use test and measurement instrument. It is ideal for any engineer or technician looking to make fast, accurate measurements in the frequency range of 9kHz to 7GHz. The unit has a wide range of features, including a preamp and built-in frequency offset, that make it suitable for a variety of applications.
