BEAM SEQUENCER TAB

The Beam Sequencer tab (see Figure 16) contains a script to
automatically step through a range of memory locations, each
of which contains the gain and phase setting of all four transmit
or receive channels in the device.
Click Select File to select a user file containing a list of memory
locations and values, and click Load File to load values into
beam memory. Each line of the beam position file contains two
values, separated by a comma. The first entry is the decimal
equivalent value, and the second entry is the hexadecimal value.
These two values make the string, which is formed by joining
together the memory address and data for each memory location.
Typical entries in a beam position file are the following:
•
1573119, 0x1800FF
•
1573174, 0x180136
•
1573429, 0x180235
The starting and ending memory locations (Start Point and
End Point, respectively), as well as the time delay between steps
(Time Delay), is entered into the corresponding fields. The
stepping operation is controlled by Start and Stop.

PHASE LOOP TAB

The Phase Loop tab (see Figure 17) provides control to increase
the phase setting of a channel with a predefined step size (Phase
Step) while dwelling at each step for a specified time (Dwell Time).
The ADI Logo Loop moves the phase in a triangular manner
around the circle, as displayed on a network analyzer.
