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.
