Frequently Asked Questions
How is this option activated?
The option is enabled by a software license keyed to the spectrum analyzer's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the spectrum analyzer from a USB drive through the option-install menu. Refer to the spectrum analyzer's user manual for the step-by-step procedure.
Is the license permanent, or does it require renewal?
The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
