KEYSIGHT's N9935A-307 option 307 adds a built-in GPS receiver to the FieldFox analyzer. The built-in GPS receiver provides geolocation tags to measurements. The geo data—time, latitude, longitude, and elevation—can be displayed and saved in data files. In addition to location information, the GPS provides an accurate frequency reference to improve accuracy.Without locking to GPS, the frequency reference accuracy is +/- 0.7 ppm +…KEYSIGHT's N9935A-307 option 307 adds a built-in GPS receiver to the FieldFox analyzer. The built-in GPS receiver provides geolocation tags to measurements. The geo data—time, latitude, longitude, and elevation—can be displayed and saved in data files. In addition to location information, the GPS provides an accurate frequency reference to improve accuracy.Without locking to GPS, the frequency reference accuracy is +/- 0.7 ppm + aging. When locked to GPS, the accuracy improves to +/- 0.010 ppm.When the GPS antenna is disconnected, FieldFox can maintain an accuracy of +/- 0.2 ppm. This is the maximum drift expected in the frequency reference when the ambient temperature changes +/- 5 deg. C from the temperature when the GPS signal was last connected. There is no specific time limit regarding frequency accuracy and GPS, temperature is the main driver. The frequency accuracy can easily be maintained for a week, if the temperature is stable. Over the long run, the aging rate will apply.In order to have GPS information, you will need: option 307 on the FieldFox, a GPS antenna such as N9910X-825 (other GPS antennas can also be used, the GPS connector on the instrument is SMA Female)*This factory-installed option is for quoting purposes only. Only available with the purchase of a new main unit. Please contact a Tessco representative for a customized SKU. Read More
