AD9958/PCB
The Chip Level Control window (Figure 45) from this particular setup shows that a 500 MHz System Clock is running with RU/RD
disabled. The Auto Clear Phase Accumulator and Auto Clear Sweep Accumulator check boxes have been selected in All Channel
Accumulator Control to ensure synchronization across channels and reinitialize the starting point once the linear sweep ends.
In the Channel Control window (Figure 46), each channel has Amplitude selected for its modulation output as shown in the
Modulation Output Type list. As discussed earlier in the Linear Sweep Options section, the Enable Linear Sweep check box found in
Linear Sweep Options must be selected in order to configure the part for the linear sweep mode of operation.
