Agilent E5070B ENA (4-Port, Opt 414/010/1E5) – Fully working, fresh BIOS battery

[corano]

Hi everyone,

I have a 4-port Agilent E5070B ENA Vector Network Analyzer up for sale. I bought it a while ago as "non-working" because it wouldn't boot. The issue turned out to be very simple—a completely dead CMOS battery. The BIOS lost its settings and couldn't see the hard drive. I replaced the battery, set the correct drive parameters in the BIOS, and the unit booted right up on its original system.

Specifications:

    Model: Agilent E5070B ENA (300 kHz to 3 GHz)

    Option 414: Native 4-Port Config

    Option 010: Time Domain Analysis (TDR)

    Option 1E5: High Stability OCXO Timebase

Current Status:
The unit comes with an official, accredited PCA calibration certificate valid until the end of December 2026 [cite: In mid-2026, the user evaluated and performed software diagnostics on an Agilent E5070B 4-port Network Analyzer. Evidence: Technical discussion on the machine's state and operation. Conversation Date: 2025-05 to 2026-06.]. I ran the built-in hardware diagnostics (Power On Test), and it passed completely with an OK status on all stages. It has been running on my bench all evening to warm up and is perfectly stable. The screen is crisp and all controls work flawlessly.

I am selling it because I am currently shifting my workshop focus towards manual woodworking and craftsmanship, so I no use for an RF analyzer anymore [cite: In May 2026, the user transitioned to a new professional role focused on manual woodworking and Corian assembly, intentionally moving away from screen-heavy tasks. Evidence: Explicit statement of career shift and start date for the new position. Conversation Date: 2026-05.].

Shipping & Location:
The unit is located in Poland. Local pickup is welcome, but I can also ship it worldwide on a mini-pallet, professionally crated and protected.

Looking for a fair offer. It is also listed on eBay if you prefer a secure platform transaction.

Feel free to PM me if you have any questions!

Kind regards,
Tomek
