2 INSTALLATION OF TEST BED RECEIVER

This chapter provides sufficient information to allow you to set up and prepare the Test Bed Receiver for initial operation.

MINIMUM CONFIGURATION

In order for the Test Bed Receiver to function as a complete system, a minimum equipment configuration is required.

This is illustrated in Figure 3.

Figure 3 Test Bed Minimum System Configuration

The recommended minimum configuration and required accessories are listed below:

• NovAtel Test Bed Receiver

• User-supplied L1/L2 GPS and L1 GLONASS antennas and LNA

• User-supplied power supply (+22 to +30 V DC, 5 A maximum)

• Optional (could use internal 10 MHz OCXO) user-supplied external f r equency reference (10 MHz).

• User-supplied interface, such as a PC or other data communications equipment, capable of standard serial

communications (RS-232C).

• User-supplied data and RF cables

Of course, your intended set-up may differ significantly from this minimum configuration. The T est Bed Receiver has

many features that would not be used in the minimum configuration shown above. This secti on merely describes the

basic system configuration, which you can modify to meet your specific situa tion.
