Keysight Agilent E4407B ESA-E Spectrum Analyzer Repair and Functional Test Services (Floppy to USB Upgrade Available)

Simbol Test Systems provides professional in-lab Keysight (Agilent) E4407B ESA-E spectrum analyzer repair and functional test services to help restore reliable performance for your RF and microwave test equipment.

The E4407B ESA-E is a versatile general-purpose spectrum analyzer covering 9 kHz to 26.5 GHz, widely used in laboratory, R&D, and production environments. Despite being discontinued, it remains a trusted platform for RF signal analysis. If the unit exhibits frequency inaccuracies, amplitude errors, display or control issues, communication faults, or general performance degradation, we can evaluate the condition and perform necessary repairs.

We also offer a floppy-to-USB storage upgrade, replacing the legacy floppy disk drive with a modern USB interface to improve usability, data transfer, and long-term reliability.

Following inspection and service, your equipment may be returned with a functional test report documenting the work performed and the operating condition of the analyzer. If additional repair work is required, we can provide a repair quotation for approval before proceeding.

Contact Simbol Test Systems with your model number and a brief description of the issue to request a repair evaluation, functional test service, or upgrade option.
