BEAM SEQUENCER TAB
The
Beam Sequencer
tab (see Figure 35) 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 choose 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 value is the decimal
equivalent value, and the second value is the hexadecimal value.
For the hexadecimal value string, the memory address is the four
most significant digits, and the data for each memory location is
the two least significant digits. Typical entries in a beam position
file include 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 (ms)
), is entered into the corresponding fields.
The stepping operation is controlled by
Start
and
Stop
.
PHASE LOOP TAB
The
Phase Loop
tab (see Figure 36) 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 (ms))
.
The
ADI Logo Loop
section moves the phase in a triangular
manner around the circle of a polar plot.
