N8995A for Stimulus/Response Measurement Suite. The option
must be enclosed in quotes.
The <LicenseKey> is a 12-character hexadecimal string. The

The License key is unique to a specific combination of option and
host ID. The host ID can be obtained remotely be using
the :SYSTem:LKEY? <Option> query or manually by pressing
System, Option Manager, and Install Info.
The query returns a string that contains the license key for a
specified application or option that is already installed in the

application is not currently in memory, but had been installed at
some previous time. The license key is unique to a specific option
and host ID.
SCPI Example SYST:LKEY “271”, “B043920A51CA”
SYST:LKEY? “271”

If the instrument does not have a license key for that option, the
query would return “ “.
