Agilent Technologies E4411B Cable TV Service and Installation Analyzer

The Agilent Technologies E4411B Cable TV Service and Installation Analyzer is a spectrum analyzer designed for CATV service work and installation tasks, covering frequencies from 9 kHz up to 1.5 GHz. Input options include a 50 Ω Type-N input and an optional 75 Ω input via Option 1DP (BNC), while RF output can be 50 Ω (Option 1DN) or 75 Ω (Option 1DQ) depending on configuration. It provides an internal amplitude reference and a 50 Ω amplitude measurement path with documented accuracy tied to reference level and attenuator settings, along with a frequency reference and related stability characteristics. Typical applications include evaluating coaxial cable loss and isolation, measuring channel power and signal quality, and diagnosing CATV installation issues in headend and customer premises environments.
