Agilent Technologies 4284A, Operation Manual

Page: 331 / 460

*LRN?
The *LRN? query (learn device setup query) tells the 4284A to send a
resp onse that con tains all the necessary commands to set the 4284A
to its presen t state. The resp onse can later b e sen t bac k to the
4284A to place it in this state. This pro vides the user with a means
of setting up a device man ually and then reading the device setting
and storing the information for later use.
