6 Configuring the RF Signal
The vector signal generator R&S SMBV100B generates RF signals with outstanding
spectral purity within the frequency range from 8 kHz up to 6 GHz and with adjustable
signal level over a wide range.
In addition to these real-time CW signals, you can generate RF signals from predefined
lists and sweep signals that vary according to the frequency or amplitude curves.
You can also apply versatile analog modulation types with definable characteristics.
The variably adjustable output level due to the built-in attenuator, allows you to vary the
RF signal level over the full level range. There are different methods to improve signal
performance and to optimize the signal quality for the particular application, or to
increase the accuracy and reliability of the generated RF signal.
The R&S SMBV100B supports R&S NRP power sensors, e.g. to monitor the output
level of the generator and to determine the level correction values for user correction
lists.
Signal modes and characteristics
The R&S SMBV100B generates unmodulated or analog modulated RF signals. You
can output the signal in fixed mode or as a signal having periodically varying frequen-
cies or amplitudes.
Signal modes for RF signal generation:
●
Unmodulated signal
Generates an unmodulated continuous wave (CW) of constant frequency and
amplitude.
For information on the signal frequency and level settings and example on how to
configure a simple CW signal, see:
– Chapter 6.5, "RF Frequency Settings", on page 289
– Chapter 6.6, "RF Level Settings", on page 292
– Chapter 2.3.1, "Generating an Unmodulated Carrier", on page 52
●
Analog modulated signal
Modulates the signal with an analog signal and generates amplitude, phase, fre-
quency and pulse modulation.
See Chapter 6.11, "Analog Modulations", on page 346.
●
Vector modulated signal
Generates an I/Q vector modulated signal
See Chapter 5, "Applying I/Q Vector Modulation", on page 277.
The R&S SMBV100B allows you to provide the RF signal with constant or varying fre-
quencies and/or amplitudes at the output:
●
Constant frequency and level (CW/Fixed mode)
The RF output signal has the set frequency and level.
●
Varying frequency and/or level
– Sweep mode
