can be carried out to compensate for the effects of the test setup (e.g. frequency
response of connecting cables).

Reflection Measurement
Scalar reflection measurements can be carried out using a reflection-coefficient mea-
surement bridge.

Generated signal input
In order to use the functions of the external generator, an appropriate generator must
be connected and configured correctly. In particular, the generator output must be con-
nected to the RF input of the R&S
FSW.
External reference frequency
In order to enhance measurement accuracy, a common reference frequency should be
used for both the R&S
FSW and the generator. If no independent 10
MHz reference
frequency is available, it is recommended that you connect the reference output of the
generator with the reference input of the R&S
FSW and that you enable usage of the
external reference on the R&S
FSW via "SETUP" > "Reference" > "External Refer-
ence".
For more information on external references see
Chapter 12.5, "Reference Frequency
Connection errors
If no external generator is connected, if the connection address is not correct, or the
generator is not ready for operation, an error message is displayed (e.g."Ext. Genera-
tor TCPIP Handshake Error!", see
