AD9959/PCB
The Chip Level Control window (Figure 41) from this particular setup shows that a 500 MHz System Clock is running, and that a 16-
level modulation-no RU/RD is being performed. Notice the Level box located in the Modulation Configuration section. The PPC Bit
pattern in the Profile Pin Config subsection of the Modulation Configuration is <010>. Referring to the table in the 16-Level
Modulation-No RU/RD section of the AD9959 data sheet, we see that this bit pattern sets up 16-level modulation on Channel 2.
In the Channel Control window (Figure 42), Channel 2 has Frequency selected as its modulation output as shown in the Modulation
Output Type box. As discussed in the Channel Constraint Guidelines section of the AD9959 data sheet, when performing 16-level
modulation on a selected channel, all other channels are available only for the single tone mode of operation.
