GNSS (GPS+) and GPS
IMPORTANT! The FieldFox may display "Ant OPEN", even when a GPS
antenna is connected to the FieldFox. If the GPS antenna is powered by
another power supply and has a DC blocking capacitor where the feed is
connected to FieldFox, then minimal amounts of current will be drawn
from the FieldFox, so the instrument will display "Ant OPEN". The
threshold to detect the presence of an antenna is approximately 1.6 mA.
GPS (Global Positioning System) allows you to 'stamp' each data trace with
your physical position in latitude/longitude/elevation format. This can be
useful when making measurements on cell towers or other antennas at remote
locations.
— With Option 307, GPS is available with the built-in receiver accessed

through the top-panel SMA (f) connector. This connector has a settable 3.3
VDC or 5 VDC bias voltage which is switched ON when GPS is set to
