8596E, 8595E, 8594E, 8593E, 8591E specifications

Agilent Technologies, a leader in test and measurement solutions, introduced the E-series spectrum analyzers—specifically the 8593E, 8594E, 8591E, 8595E, and 8596E models—designed to meet a wide range of frequency analysis needs. These models are part of Agilent's legacy of portable bench instruments that provide high performance in a compact form factor.

The Agilent 8593E is a versatile spectrum analyzer that covers frequencies from 9 kHz to 3 GHz. It features a high-resolution display and features like amplitude and frequency accuracy that make it ideal for troubleshooting and evaluating RF components. The 8594E extends the frequency range to 6 GHz, making it suitable for work in industries involving advanced telecommunications and broadcasting applications.

The 8591E is a more economical option in the lineup, operating in the same frequency range as the 8593E. It is designed for basic spectrum analysis tasks, emphasizing ease of use and practicality. In contrast, the 8595E caters to more demanding applications, offering frequency coverage up to 13.2 GHz, making it an ideal choice for emerging technologies such as 5G.

On the higher end, the 8596E model presents an extended bandwidth, covering frequencies from 9 kHz up to 22 GHz. This model includes advanced features such as built-in preamplifiers, which enhance its sensitivity, and a wide range of analysis capabilities. This allows engineers to carry out thorough investigations of both linear and non-linear devices in a single setup.

Key technologies across these models include Agilent's patented digital signal processing, which increases the accuracy and speed of frequency sweeps while minimizing noise. The instruments also boast features such as an integrated tracking generator, Applicator Simulator, and a variety of measurement applications that cater to both basic and complex analysis tasks.

In essence, the Agilent E-series spectrum analyzers are defined by their precision, versatility, and cutting-edge technology, thereby establishing themselves as essential tools for engineers and technicians across telecommunications, electronics testing, and regulatory compliance testing. Whether for fieldwork or lab environments, these analyzers are built to deliver reliable performance.
