R&S SGT100A
The function records all sent commands, received responses and messages, and
stores them in an internal database. If "live mode" is disabled, you can display the
recent traces upon request, using the "refresh" button. You can also store the log in
a file.
9.7 Monitoring remote control operation with R&S SGMA-
GUI
The R&S SGMA-GUI can be used to monitor the behavior of one or more instruments
while they are remote controlled.
A typical configuration consists of one monitor, controllers and instruments. The moni-
tor is the remote PC on which the R&S SGMA-GUI is installed and the controller is the
remote PC on which the application program runs.
Simultaneous control of an instrument from a controller and a monitor can lead to colli-
sions whenever both the controller and the monitor utilize the same remote channel.
These collisions are indicated by an error message in the "Info" line, e.g. "Query inter-
rupted" or "Resource locked". Simultaneous monitoring and control over the same
remote channel is only possible, if the used protocols support
viLock()/viUnlock() and the remote program use these functions.
The
nation of remote channels is possible or not and if there are any restrictions.

Where:
●
OK: communication possible, no collisions
*) the R&S SGMA-GUI always uses the LAN device name instr1, see also
ter 9.1.2.3, "VXI-11
●
X: communication is not possible without collisions
●
viLock/viUnlock: communication is only possible, if the remote control com-
mands are enclosed in a viLock () - viUnlock() pair.
The R&S SGMA-GUI uses the viLock()/viUnlock() functions.
