Touchstone file errors
Some errors concerning
.s2p
correction files do not cause warnings in the status bar.
Also, they do not provide results in the system error queue, but do display messages
or return errors in remote control.
Network connection errors
If you cannot connect to the external frontend, check the status bar or error queue of
the R&S
SMW for error messages. See Table 5-1
If no messages are available, check the "LAN" and "Power" status LEDs on the exter-
nal frontend. Permanent red lights indicate an error, usually hardware problems, e.g. if
the fans are off. In this case, the instrument is automatically put in a safe (error) state
to avoid damage. A LAN connection is no longer possible. Try switching the external
frontend off and on again.
If the problem persists, contact Rohde & Schwarz, see chapter "Contacting Customer
Support" in the R&S
SMW user manual.
