Request for help with codes for the E4404B spectrum analyzer
« on: September 24, 2026, 09:33:30 pm »

Hello,

I have an older spectrum analyzer, model E4404B. The firmware version currently installed is A.09.01.

Serial Number: MY41440451
Host ID: D7D2A47A

I am looking for the license codes for the following options:

226, 219, J35/J36, 225, 228, 229, 1DR, 1DS, 1D6, 231, 202.

I would greatly appreciate it if anyone could help me obtain these license codes.

Thank you very much in advance for your time and assistance.
