searchRx.antenna.switchCmnd
Syntax
searchRx1.antenna(1..16).switchCmnd:
integer
Description
This command is used to program the RF switch. The value is logically compared with
searchRx.antenna.switchMask (page 148)
to determine which switches must be changed
such that only those are changed when the antenna selection changes. This approach is used
to minimize relay activity and maximize switch contact life. The parameter value may be
given either as an integer or hexadecimal. The hexadecimal value should be preceded with
“0x” as shown in the figure and example.
Figure 50.
Antenna switch
command
translation
This hexadecimal number uses one digit to define a connection for each of the six banks in
the switch. Valid values for a single hex digit are 0, 1, 2, 4, or 8 (0 = don't change). See
.
Example
The hex value to specify using connection 13, and 41 is 0x020080:
- bank 1 is 2
nd
place from right, 8 here selects connection 13
- bank 4 is 5
th
place from right, 2 here selects connection 41
The integer (decimal) equivalent value of 0x020080 is 131,200.
Each antenna must have a switchCmnd and switchMask as shown for antennas 1, 2, and 8 in
the following example:
searchRx1.antenna1.switchCmnd
:
0x00000000
searchRx1.antenna1.switchMask: 0x0000F00F
searchRx1.antenna2.switchCmnd
:
0x00000002
searchRx1.antenna2.switchMask: 0x0000F00F
searchRx1.antenna8.switchCmnd
:
0x00002080
searchRx1.antenna8.switchMask: 0x0000F0F0

To define the switch command to select antenna 8,
banks 1 and 4 are relevant as shown below.
Switch settings to pick antenna 8:
- bank 1, position 3 (13) (bank 1 = 2 place digit)
- bank 4, position 1 (41) (bank 4 = 5 place digit)
hex value 1 selects bank connector 0
hex value 2 selects bank connector 1
hex value 4 selects bank connector 2
hex value 8 selects bank connector 3
hex value 0 means no change
