Generating Signals With Extended Bandwidth - R&S SMW-K555 User Manual

R&S SMW-K555
The alignment procedure applies corrections to the local oscillator (LO) phase. If
the alignment runs correctly, the "Bw Ext" softkey displays no errors.
If you change parameters of the RF output signal at the R&S SMW, the RF ports are
not aligned anymore. For example, if you change the frequency or the level of the RF
output signal. Also, RF ports are not aligned if you change the bandwidth extension
setup file.
Align the RF ports again.

3.4 Generating signals with extended bandwidth

This chapter provides an overview on how to generate signals with extended band-
width at the R&S SMW. It covers the following topics:
●
"To activate a bandwidth extension setup"
●
"To generate an ARB signal with extended bandwidth"
To activate a bandwidth extension setup
The R&S SMW is configured and aligned for bandwidth extension, see
"Configuring the R&S
1. Select "System Configuration" > "Multi Instrument" > Bandwidth Extension".
2. Select "State > On".
The block diagram of the R&S SMW adjusts automatically for a bandwidth exten-
sion setup.
