In the Channel Output Config window (Figure 43), Channel 2 has a frequency output of 3 MHz (Frequency 00 box). When this setup file
is loaded, profile pins P1 and P3 are pressed as shown in the Profile and RURD Pin Control Section. 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, then 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 will
be 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 All Channels@10 MHz_half to full scale.stp file found in the Amplitude folder.
