Phases are specified in degrees and can be set from 0.0 to 365.0 degrees. The
registers shown on the front panel range from 0 at the top down to 15 at the bottom, but
the number of phase registers available vary depending on the board. See your board
manual for the number of output phase registers available. The specific phase registers
must be set in the register bank in order to be used in an instruction as described above. If
the register box is white, then it will be programmed to the board and can be used. If it is
grayed out, it will not be programmed and therefore cannot be used in an instruction. To
make a grayed out register box white, simply click inside the box and type the value you
want. To gray out a white register box, right-click on the box, select “Data Operations”, and
then select “Delete Element.” The register chosen by the “DDS0 Phase Register Selects”
instruction from Figure 3 corresponds to the phase registers under the heading, “DDS0
Registers” in Figure 5. Similarly the “DDS1 Phase Register Selects” instruction
corresponds to the phase registers under the heading, “DDS1 Registers”.
Amplitudes are specified as a percentage of full power and ranges from 0.0 to 1.0.
The registers shown on the front panel range from 0 at the top down to 3 at the bottom.
There are only 4 amplitude registers available. The specific frequency registers must be
set in the register bank in order to be used in an instruction as described above. If the
register box is white, then it will be programmed to the board and can be used. If it is
grayed out, it will not be programmed and therefore cannot be used in an instruction. To
make a grayed out register box white, simply click inside the box and type the value you
want. To gray out a white register box, right-click on the box, select “Data Operations”, and
then select “Delete Element.” The register chosen by the “DDS0 Amplitude Register
Selects” instruction from Figure 3 corresponds to the amplitude registers under the
heading, “DDS0 Registers” in Figure 5. Similarly the “DDS1 Amplitude Register Selects”
instruction corresponds to the amplitude registers under the heading, “DDS1 Registers”.
