When tuning, the SY3 System uses 3 separate components:
1.
The SY3 Antenna
2.
The Analytics Tower and cables
3.
EMC Field Probes
The SY3 Antenna
The SY3 antenna should be in the same location and polarization as the antenna configuration that it is using.
Moving the antenna to another location and polarization may cause an increase in VSWR and
antenna performance.
The Analytics Tower
The Analytics tower should only have the DB
-
25 control connected during testing. This cable is necessary for
controlling the SY3 Antenna element lengths.
To prevent damage while testing, disconnect all coaxial cables from the OptimizIR EMC while
testing
EMC Field Probes
Optimal placement of field probes will vary depending on the frequency and polarization of the SY3 Antenna.
We recommend the use of multiple field probes to accurately map the field generated by the SY3 Antenna, if
possible.
In Horizontal Polarization:
We recommend positioning the field probe(s) up to
48”
to the right or left of the SY3 Antenna from
30
MHz—
75
MHz
.
We recommend positioning the field probe(s)
18”
to the right or left of the SY3 Antenna from
75
MHz—
200
Mhz
.
In Vertical Polarization:
We recommend positioning the field probe(s)
6”
to the right or left of the SY3 Antenna from
30 MHz —
200 MHz
.
Optimal field probe position will depend on the chamber geometry and resulting SY3 antenna configura-
tions. Your experience may vary.
