9.4 Advanced remote control using fast socket

Fast settings
The socket interface can be utilized not only to transfer text messages, e.g., SCPI
commands 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
protocol which does not support routing. Therefore a controller PC can only control
devices within its own network segment using the fast socket method.
To use the advantage of the fast settings, the following prerequisites must be fulfilled:
●
On Windows operating systems, the fast socket driver must be installed.
●
The application program must be run with root/administrator rights.
●
The fast settings must be enabled with the function rssgt_useFastSettings
(see also
The instrument driver uses the fast settings method whenever possible. Fast settings
apply for the parameters frequency, level, RF state, I/Q modulator state, IQ wideband
state, digital attenuation, frequency offset, phase offset, trigger, segment trigger, next
segment index. In all other cases, SCPI messages are sent.
