License Key – Install Application/Option
:SYSTem:LKEY <"option">, <"license key">
:SYSTem:LKEY? <"option">
This command enters the license key required for installing the
specified new application or option. The query returns a string that
contains the license key for a specified application or option that is
already installed in the instrument. The license key will also be
returned if the application is not currently in memory, but had been
installed at some previous time.
Example:
:SYST:LKEY "BAC", "123A456B789C"
Remarks: An option is a three character string that specifies the
option or application that is to be installed, as found in
the Ordering Guide (for example, BAH for GSM
Measurement Personality). The option name must be
enclosed in quotes.
A license key is a 12-character hexadecimal string
given with the option. The license key is unique to a
specific option installed in the instrument with a
specific host ID, as returned by :SYST:HID?. The
license key must be enclosed in quotes.
