GNSS (GPS+) and GPS
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 3.3 VDC
bias voltage which is switched ON when GPS is set to Internal. This system
is designed for use with an active antenna such as the Keysight
N9910X-825.
Delete All CFG Options is to be used by Service Personnel ONLY.
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.
