In the Channel Output Config window
frequency of 20 MHz, Channel 2 an output frequency of 30 MHz, and Channel 3 has a frequency output of 40 MHz. Because the RU/RD
operation is enabled, the Enable ASF and Enable Auto ASF boxes are checked. The amplitude scalar factor (ASF) is set to 1 (full scale).
Therefore, the output signal will be 0 MHz until the correct profile pin is selected to ramp the frequency up to full scale. When this setup file
is loaded, profile pins P0, P1, P2, and P3 are pressed as shown in the Profile and RURD Pin Control Section. P0 controls Channel 0, P1
