External Frontend [x]:
Touchstone file insuffi-
cient frequency range 350, "Touchstone

Correct the file.

Correct the path and filename and make sure that
the file is stored on the instrument under
C:\R_S\INSTR\USER\external_frontends\

Touchstone file errors
Some errors concerning
.s2p
correction files do not cause warnings in the status bar
and do not provide results in the system error queue, but do display messages or
return errors in remote control.
Problems with connection
If you cannot connect to the external frontend, check the status bar or error queue of
the R&S
FSV/A for error messages (see also "Error messages" on page 437).
If no messages are available, check the "LAN" and "POWER" status LEDs on the
external 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 service, as described in Chap-
ter 13.7, "Contacting customer support" , on page 1435.
Problems during operation
Problem: I cannot set the analysis bandwidth to values up to 1 GHz despite an instal-
led B1000 option
......................................................................................................... 439
Problem: The analyzer does not show the signal sent by a signal generator using the
same external frontend
............................................................................................... 440
Problem: I cannot set the analysis bandwidth to values up to 1 GHz despite an
installed B1000 option
Possible Solution:
The B1000 option is only available for input frequencies starting at
7.5 GHz. Thus, to use the extended analysis bandwidth, the external frontend must
downconvert all RF input signals to an IF frequency above 7.5 GHz.
Note: Therefore, you must set the Frequency Band Configuration to "IF High" in the
Frontend configuration settings .
