Connect RF of the R&S SMA100B to a signal analyzer, for example R&S
®
FSW, to dis-
play the generated signal.
For the required settings of the signal analyzer, refer to its user manual or its online
help.
2.3.2 Generating an RF Frequency Sweep Signal
The "Sweep" operating mode allows you to generate an RF signal with periodically
varying frequencies or amplitudes.
This example deals with an RF signal with varying frequency and constant level. To
configure the sweep, you need to determine a defined start and end frequency with
constant time intervals between the frequency steps.
The sweep function does not require specific options.
1. On the front panel, press the [Preset] key to set a defined initial instrument state.
2. Set the signal output level, if required, e.g. set "Level > -25 dBm".
3. In the tile diagram, select "Sweep" > "Frequency Sweep".
4. In the "General" tab:
a) Select "Mode > Auto" to run the sweep continuously.
b) Select "Shape > Sawtooth" to set the waveform shape of the sweep signal.
c) Select "Spacing > Linear", to determine the calculation method for the fre-
quency shift of a step.
d) Set "Dwell Time > 15.0 ms", to determine the time interval of the sweep steps.
5. Select the "Frequency Range" tab.
