Spectrum Analyzer Agilent E4407B

Product Description

The Agilent Technologies E***7B spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several *0s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Agilent Technologies E***7B. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Agilent Technologies E***7B Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Agilent Technologies E***7B spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Agilent Technologies E***7B spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
The E***7 offers leading performance in accuracy with a guaranteed overall amplitude accuracy of less than 1.0 dB error (< 3 GHz ) based on traceable and warranted specifications. Other mid-range analyzers may specify only typical performance levels. The ESA excels in overall amplitude accuracy whether comparing guaranteed specifications or expected levels of performance. The E***7 provides a warranted internal frequency reference that may not be available in other mid-range analyzers. Further, the ESA has excellent frequency readout accuracy, a function of the frequency reference error as well as the span error coefficient, RBW, center frequency, and number of sweep points. The E***7 offers top performance thanks to its optional built in low noise, high gain preamplifier. Achieving a Displayed Average Noise Level (DANL) of better than ¿**7 dBm. A spectrum analyzers dynamic range is a function of both its display average noise level (DANL) performance and its intermodulation distortion performance. The ESA third order intermodulation distortion performance is excellent with a performance level of **6 dBm third order intercept (TOI) (*7.5 for basic analyzer configurations). Combined with the E***7¿s DANL performance of ¿**0 dBm/Hz, the overall dynamic range sets the standard for the medium class analyzer. In addition, the E***7 features a standard 5 dB step attenuator making it easy to optimize the spectrum analyzers mixer level settings to achieve the best dynamic range. The E***7¿s automatic, internal background alignment feature gives consistently accurate results over varying temperatures. This is especially beneficial when operating the ESA outdoors or in varying temperature conditions. Further, the ESA provides guaranteed performance specifications over wide temperature range of 0 to *5 degrees centigrade. The E***7 spectrum analyzer features very fast sweep times. With sweep times as low as 1 ms for an RF sweep and *5 ns for a zero span sweep the ESA has the fastest sweep times for an analyzer in its class. Fast sweep times are particularly useful when searching for low level signals.
