Con fi gure the GPS7 Module
When you fi rst receive your GPS7 module, there are a few things you need to do,
and a few things you should know, before putting it into service. This section
includes information about the following:
Performing an internal frequency calibration
Performing a gain calibration
Understanding the GPS antenna system
Understanding signal quality
Understanding time fl ow
Con fi guring module settings
Oven Calibration
Procedures
If you are installing a module into an existing mainframe, you need to set the
internal frequency of the mainframe internal oscillator and characterize the
oscillator frequency as a function of voltage before putting it into service. This
latter calibration can only be performed in factory mode when the instrument
is out of service.
If you have received your GPS7 module already installed in a mainframe, you can
set the internal frequency after putting the module in its operating environment
and allowing it to reach a stable operating condition.
