In the Channel Output Config window (Figure 43), Channel 0 has a frequency output of 3 MHz (Frequency 00 box). When this setup
file is loaded, Profile Pin P1 and Profile Pin P3 are pressed as shown in Profile and RURD Pin Control. In 16-level modulation, P3 is the
LSB and P0 is the MSB. This explains why when this setup file is loaded, an output of 18 MHz is shown because 0101 binary = 5, and
Profile Register 05 contains 18 MHz as its output. If no profile pins are selected, the output frequency is equivalent to the value entered
in the Frequency 00 box (3 MHz in this setup). If all profile pins are pressed, the output frequency is equal to 48 MHz, the contents of
Profile Register 15 (1111 binary).
Linear Sweep Mode
Open the Linear Sweep Mode folder to access the linear sweep mode of operation example setup files. Once this folder is opened you are
presented with the window shown in Figure 44.
For a frequency sweep, open the Frequency folder; for a phase sweep, open the Phase folder; and for an amplitude sweep, open the
Amplitude folder. This section discusses the Both Channels@10MHz_half to full scale.stp file found in the Amplitude folder.
