Frequency and frame

timing accuracy test

This procedure checks that the frequency and frame timing are accurate when
locked to GPS or GLONASS.

Frequency accuracy when locked to GPS or GLONASS.

Check that the antenna is connected to both a GPS7 reference module (or other
reference instrument) and the

GPS ANT

connector of the SPG8000 under test.

Figure 23: Setup for frequency accuracy and frame timing accuracy tests

Check that both the reference module and the SPG8000 under test have been
on for 20 minutes to allow the ovens to warm up.

Check the signal quality on the reference module as follows:

Press the

MODULE

button until

GPS7

appears.

Use the up (

▲

) or down (

▼

) arrow button, if needed, to select

STATUS

Check that the top line of the status display shows

Locked

Use the left (

◄

) or right (

►

) arrow button to select

Signal Quality

Check the value on the reference unit. A value of 30 or above is adequate.
