I just bought a E4401B Spectrum analyzer. The previous owner said me that the 1DR option was present. But nothing is shown in the system menu.
Is it possible to confirm that the 1DR option license has been issued for this equipment? If yes can you give me the license activation key.
Product Number: E4401B
Serial Number: US41061605
Host ID: 2D70905E
Thank you for your help.
