Example:
●
"Data Source > External"
●
Modulation with 3 bits per symbol
●
"Symbol Clock Slope > Positive", i.e. the active edge of the symbol clock is the ris-
ing edge
●
Clock active edge falls at the center of the first bit of each symbol
Figure 5-13: Throughput delay (symbols indicated by different colors)
The throughput delay is the time between center points: The center of the modulation
symbol at the RF output and the center of the first bit in each symbol in the external
data.

5.6.3.4 Modulation Settings
Access:
► Select "Baseband > Custom Digital Mod > Modulation".
This tab provides access to the modulation settings, e.g modulation type, FSK devia-
tion, or modulation depth. The dialog shows the theoretical constellation diagram of the
selected modulation.
