16​Indoor and Outdoor Mapping – Option 352 (Requires Spectrum Analyzer Mode (Option 233), and GPS Receiver (Option 307))

Option 352 maps signals that were measured using the SA RF Input Port 2 connector.

The FieldFox requires Option 352 for outdoor mapping and GPS (Option 307) installed. And, one of the following, an Over–the–air (OTA) mode (LTE FDD Option 370, or 5G NR / 5G NR EVM Conducted / 5G TF Option 378), or Channel Scanner mode (Option 312). Also, requires browser that supports HTML5 (i.e., web browsers not supported: IE6, IE7, and IE8).

Recommended, but not required, preamplifier (Option 235) to improve receiver sensitivity.

Keysight's FieldFox handheld analyzer (with Option 352) combined with a USB triaxial antenna (p/o EMF Measurements – Option 358) provides a unique, portable solution for indoor and outdoor mappings in the field. Option 352 adds indoor and outdoor mapping capability to FieldFox analyzers, so that FieldFox can import maps from OpenStreetMap (OSM) for data collection and data plotting to the map directly on the FieldFox instrument display. The FieldFox Map Explorer resides at the System level and enables you to download, import/export, and view outdoor maps. All of the other data logging, record/playback, plotting data on indoor/outdoor maps can be enabled within the following modes:

—​Channel Scanner (Option 312)

—​Over-the-Air (OTA) LTE FDD (Option 370)

—​Over-the-Air (OTA) LTE TDD (Option 372)

—​Over-the-Air (OTA) 5G NR / 5G TF (Option 378)

Using a direct wired LAN connection with access to a network and the internet, FieldFox will automatically access OSM once location coordinates (latitude and longitude) and zoom levels are entered the Map Explorer menu. If using the FieldFox Map Support Tool, OSM map files can be downloaded to a *.zip file and imported to FieldFox internal memory. If the FieldFox GPS receiver is enabled and OSM maps have been previously saved to FieldFox with those GPS coordinates, FieldFox will automatically load the corresponding map to match the GPS coordinates.

—​Then Add Point – adds a new bearing location then:

—​Press Direction Line OFF ON – Enables/disables the line of bearing (default = OFF).

—​Press Adjust Angle – Enters the angle of the current point’s line. Rotate the line about the current point (your current location) to point towards the highest signal strength seen by your directional antenna. You can rotate the knob to rotate the line, or you can type an angle into the active entry directly.

—​Press Line Length – Enters a value for the line’s length. Adjusts the length of the line of bearing to extend it far enough to allow other points to cross, indicating a possible emitter location.

—​Press Accept Point or Back – verifies the new point is to be added and returns to the previous menu.

—​Then Edit Points – Opens up menu of bearing point editing softkeys. Choose from:

—​Press Select Point – Enter the point you want to edit. Then you can directly enter a new angle or line length or use the arrows, or the rotary knob to edit these values.

—​Press Direction Line OFF ON – Enables/disables the direction line (default = OFF).

General Troubleshooting

If your Mapping setup is not behaving as expected:

—​Verify setup is correct by referring to “How to Set Up Mapping Settings” on page 512.

—​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.
