Press this submenu key to display the current GPS information. Refer to GPS Info.
GPS Voltage
Press this submenu key to set the source voltage to be either 3.3 V or 5 V depending on the GPS receiver being used. GPS antenna voltage is set to 3.3 V by default to prevent accidental damage to lower‑voltage GPS antennas.
5 V is the recommended setting for Anritsu GPS antennas.
Reset
Press this submenu key to set the number of tracked satellites to 0 and to erase any almanac data, along with saved coordinates. The process of searching for and reacquiring satellites begins again.

GPS Info
• Tracked Satellites
Shows the number of tracked satellites (three are required to retrieve latitude and longitude, four are required to resolve altitude). Generally, the larger number of satellites tracked, the more accurate the information.
• Latitude and Longitude
Shows location in degrees, minutes, and seconds.
• Altitude
Shows altitude information in meters.
• UTC
Coordinated universal time.
• Fix Available
The cold start search sets are established to ensure that at least three satellites are acquired within the first couple of minutes. When three satellites are found, the receiver computes an initial fix (typically in less than two minutes). Fix Not Available means that the initial position has not been established.
• Almanac Complete
The system Almanac contains information about the satellites in the constellation, ionospheric data, and special system messages. In a cold start, the GPS receiver does not have any navigation data so the receiver does not have a current almanac. A complete system almanac is not required to achieve a first position fix. The availability of the almanac, however, can significantly reduce the time to first fix.
• Antenna Status
OK
Antenna is connected properly and antenna is working properly
Short/Open
A short or open exists between the antenna and the connection. If this message is displayed, then remove and replace the GPS antenna. If the message persists, then try another Anritsu GPS antenna. If the message persists, contact your nearest Anritsu Service Center.
• Receiver Status
Current status of the receiver.
• GPS Antenna Voltage and Current
Shows the voltage and current for the GPS antenna.
