The measurement is making 100 averages, which requires approximately three minutes to stabilize the noise level. After completion, stop the measurement and note the levels.

Passing the test

You have passed the test if the average noise level is below –122 dBm. If your system is equipped with a navigator, perform the tests in “Test 4 - GPS receiver testing" on page 116. If you experience problems in setting up the test, refer to “Troubleshooting your E6474A system" on page 102.

Test 4 - GPS receiver testing

If you have an Agilent digital receiver, make sure that you have tested the receiver using either method 1 (page 106), method 2 (page 112), or method 3 (page 114) described earlier in this chapter. It is recommended that you know the GPS position, the longitude and latitude, of where you do the test.
