AD9958/PCB
In the Channel Output Config window (Figure 47), both channels (Channel 0 and 1) have an output frequency of 10 MHz (Frequency
00 box). The Enable ASF check box is deselected because a linear amplitude sweep is being performed. The amplitude scalar factor (ASF)
is set to 0.5 (half scale), denoting that the sweep begins at half scale and sweeps up to full scale (Amplitude 01-ending point of sweep). In
Linear Sweep Setup, the rising/falling step size and step intervals of the sweep are equal, indicating the sweep rises and falls at the same
rate. P2 controls Channel 0 and P3 controls Channel 1. To sweep up to full scale, press the profile pin associated with the channel’s
output. To return to half scale, unselect the profile pin.
