    Connect the Antenna Correctly When connecting the SY3 Antenna to the SY3 Analytics Tower, ensure that all connections are fastened se- curely. Utilize both screws on the DB-25 connecter to prevent accidental disconnection of the cable during use.
  • Page 4 Observe Antenna Power Ratings The SY3 antenna is rated to 2500 Watts at 2.5 : 1 VSWR. Operating at higher RF power or higher VSWR values can result in damage to the system. Burn Prevention The SY3 Antenna enclosure underside surface may be hot during and immediately after transmitting.

    Section 1: The SY3 Stand allows for quick levelling and adjustments of the SY3 Antenna. It uses a PanaVise head to tilt the SY3 Antenna between horizontal and vertical polarizations, as well as four leveling feet for fine tuned con- trol.
  • Page 6 SY3 SYSTEM ASSEMBLY: SY3 STAND Using a 3/16” hex (Allen) key, secure the four legs by tightening the set screws as shown in Figure 2. Ensure that the leveling feet are facing the ground as shown in Figure 1 on the previous page before tightening.

    SY3 SYSTEM ASSEMBLY: RECEIVE ANTENNA AND STAND Section 3: The SY3 System uses a 0.03—1 GHz Biconical Antenna and non-conductive stand to measure and optimize for signal strength while tuning. Figure 8 demonstrates how the non-conductive stand is assembled Figure 8 13406 SE 32nd St, BELLEVUE WA, 98005 WWW.STEPPIR.COM...

    3. The analytics tower and cables The SY3 Antenna The SY3 Antenna should be placed inside of the EMC chamber 90cm from the edge of the bench, and cen- tered on the bench, as described in MIL-STD-461G, RS 103. This measurement should be taken from the center of the front element fiberglass support tube.
  • Page 15 Antenna as shown in Figure 14. We recommend that the Receive Antenna should also be positioned 61cm (24") to the right of the centerline of the SY3 Antenna when in horizontal polarization as shown in Figure 15 on the next page. In vertical polarization the Receive Antenna should be positioned on the centerline of the SY3 Antenna as shown in Figure 14.

If the SY3 Antenna is being used in a new location, it is necessary to create a new “Antenna Configu- ration” for both the Horizontal and Vertical Polarization.

    103 test. They are not rated to the 2500W power limit of the system. It is the customers responsibility to use a coaxial cable for the SY3 Antenna during the RS 103 test that is suitable for at least 2500W in the 30-200MHz frequency range.

  • Page 21: Section 9: Manually Testing

    Section 9: If you do not have the SY3 system integrated with TILE! or your own proprietary testing software, you will need to perform the test manually. In order to perform the test manually you will need to send the antenna to a test frequency, apply RF power to the antenna at the correct frequency, measure the E-field, turn off RF power to the antenna, then send the antenna to the next test frequency, and repeat.
  • Page 22 SY3 SYSTEM USER GUIDE: MANUALLY TESTING Select the appropriate frequency using the dropdown shown in Figure 21. You can also change frequencies by clicking the “<<“ or “>>“ buttons shown below. Move down one frequency Move up one frequency Figure 21 13406 SE 32nd St, BELLEVUE WA, 98005 WWW.STEPPIR.COM...
  • Page 23 “Retracted”. Figure 22 When “SEND TO ANTENNA” is clicked, the interface will show that the SY3 Antenna is adjusting (Figure 23), then will show the new Configuration and Frequency on the Status Menu when done (Figure 24). The Status Menu can only track the SY3 Antenna element lengths while the OptimizIR EMC is pow- ered on.
