CHAPTER 8

Advanced Use of the Analyzer – Tips and Tricks

Data from the weather station is automatically obtained during the measurement and saved on

data – see measurement parameters in Appendix B. The measured data can be displayed as

parameters from the Weather group.

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).
