14​5G Rapid Prototype Phased Array Antenna – Option 360

Option 360 measures signals at the SA RF Input Port 2 connector.

Option 360 requires the FieldFox to have SA mode (Option 233 on combination analyzers), and GPS (Option 307) installed.

—​Attenuator set to 0 dB

—​Preamplifier set to ON

—​Correct Band, Channel, and Center Frequency entered

—​GNSS set to Internal

—​Frequency Ref set to GPS

—​ADC errors: Use Scale/Amptd > Range to adjust the absolute power level (dBm).

For some data views, you need to press More to view the Range softkey.

—​No data displayed: Press Meas Setup 4 then

——Verify the correct Antenna Settings have been entered.

—​The FieldFox’s displayed annotation indicates "Check LAN connection. Check IP address." during pinging.

Verify:

——The LAN address for first 3 fields matches the Static IP address of FieldFox. For example, if the Ball Antenna IP address is 192.168.1.10, set FieldFox Static IP address to 192.168.1.xx. “xx” must be different number than shown in the last field of the for Ball Antenna. Refer to Figure 14-15 on page 465.

——Power is connected to the PAA. If the power is not connected indicator is flashing () on the left side of the FieldFox display, verify your connections.
