signals and marker signals specific to the firmware option. With suitable marker set-
tings for instance, you can mark slot or frame boundaries or mark the start of a particu-
lar modulation symbol.
This example extends further the configurations performed in Chapter 2.3.2, "Generat-
ing a Digitally Modulated Signal", on page 53. We assume a default connector map-
ping (see Figure 2-8).
This test setup requires one oscilloscope, like the R&S
®
RTO, as additional equipment.
1. In the block diagram, select "Block Diagram > Baseband > Misc > Custom Digital
Mod > Marker" tab.
2. Select "Marker Mode > Marker 1 > Pulse" and "Divider = 32".
Generated is a periodic marker with marker frequency of 120 KHz. The signal is
output at the User 1 connector of the R&S SMBV100B (see Figure 2-8).
3. Use a suitable cable to connect the User 1 connector of the R&S SMBV100B to the
monitoring instrument, for example oscilloscope like R&S
®
RTO. See Figure 2-10.

4. Use a suitable cable to connect the I OUT connector of the R&S SMBV100B to the
monitoring instrument.

nals", on page 94.
2.3.5 Verifying the Generated Signal with the Graphics Display
It is often useful to check the spectra of the configured signals, before you enable the
RF output of the instrument.
