V 86
Set Linearizer
.
(see note 3)
To command the linearizer, send gain, phase, and
amplitude setting in the form NNN NNN NNN (each setting is separated by a
space) after V. To lock this setting in, see command X. Set Example: {AV123
211 012} where A is the address.
W 87
Query Linearizer
.
(see note 3)
To query the linearizer, send W with no argument.
The response will be in the form NNN NNN NNN (gain, phase, amplitude).
X 88
Lock Linearizer Settings.
(see note 3)
Send this command to lock in (save to non-
volatile memory) linearizer settings. This command should be sent after the
desired linearizer settings have been achieved.
