included in the instru-
ment driver.
Settings for some parameters like level and frequency accelerate.

10.4 Advanced Remote Control Using Fast Socket
Fast settings
The socket interface can be utilized not only to transfer text messages e.g. SCPI com-
mands but also to carry register based remote control messages. The latter mode is
called fast settings mode. The fast socket communication is based on the Ethernet pro-
tocol which does not support routing. Therefore a controller PC can only control devi-
ces within its own network segment using the fast socket method.
