When tuning, the SY3 System uses 3 separate components:
1.
The SY3 Antenna
2.
The Mini
-
Bicon Receive Antenna
3.
The analytics tower and cables
The SY3 Antenna
The SY3 Antenna should be placed
1 meter
from the EUT, as described in MIL
-
STD 461
-
G.
This measurement should be taken from the center of the front element tube.
In the Horizontal Polarization, the center of the front element tube should be
57"
from the ground of the cham-
ber. This height adjustement can be made using the handwheel on the stand. The antenna can then be lev-
elled side to side using the handwheel on the PanaVise attachment. The antenna can be levelled front to
back using the adjustable feet on the stand.
In the Vertical Polarization, the center of the front element tube should ideally be at least
17"
from the floor
and ceiling of the chamber, and must be
at least 10"
from the floor and ceiling of the chamber to avoid perfor-
mance loss.
The Receive Antenna
The Mini
-
Bicon Receive Antenna should be placed
12"
above the EUT, as measured from the center body of
the Biconical antenna, in horizontal and vertical polarization.
The polarization of the Receive Antenna should match the polarization of the SY3 Antenna
We recommend that the Receive antenna should also be positioned 24" to the right of the SY3 Antenna.
After extensive testing, we found that this placement yielded best results in our test chambers
The Analytics Tower
The Analytics Tower connects to the SY3 antenna using the N
-
Type to N
-
Type LMR
-
400 low loss coaxial ca-
ble and the DB
-
25 Control Cable. The Analytics Tower connects to the Receive Antenna using the BNC to N
-
Type LMR
-
400 low loss coaxial cable.
The Receive Antenna must be connected to the
“
PROBE
”
connection on the OptimizIR EMC, and
the SY3 Antenna must be connected to the
“
ANTENNA
”
connection on the OptimizIR EMC. Double
check these connections!
If the SY3 is being used in a new location, it is necessary to create an Antenna Configuration for
both the Horizontal and Vertical Polarization.
