CHAPTER 8

Advanced Use of Your Analyzer – Tips and Tricks

8.6.2 GPS Receivers

The analyzer can be connected to the following GPS receivers:

• GPS Receiver ZZ-0249 – for measurement of latitude, longitude, altitude and position error

Please refer to the user manual for Noise Monitoring Terminal Type 3639-A, B and C

(BE 1818) for details on how to mount and connect the GPS receiver using Utility Unit

ZH-0689.

• ND-100S GPS USB Dongle from Globalsat (www.globalsat.com.tw) – for measurement

of latitude, longitude and altitude

• BU-353 Cable GPS with USB Interface from Globalsat – for measurement of latitude,

longitude and altitude

The GPS receivers with USB interface can be connected directly to the USB port on analyzers

with hardware version 4. On hardware versions 1 – 3, the GPS receivers can be connected

using USB Adaptor AO-0657.

The first time you connect the GPS receiver to the analyzer (or if it has been several days since

you last connected them), be sure to be in an open area with a clear view to the sky (such as a

park or empty field). Wait for GPS initialization to complete. This may take a few minutes

depending on factors such as the distance from the previous coordinates, GPS signal strength

and surrounding terrain (tall trees and buildings can block the satellite signals).

Once the Latitude and Longitude (from the Special parameter group) display data, a fix has

been initialized (the LED on the GlobalSat GPS will also start to flash).

In some cases initialization can take up to several minutes depending on the conditions

mentioned above before complete GPS data are displayed on the screen. The GPS may get a

faster fix if connected through a small USB cable (delivered together with the GPS).

If a GPS receiver is connected when data is saved in a project, a GPS note is automatically

created as an annotation with the GPS information.

See more details on GPS notes in section 3.5.
