Accuracy

The accuracy is calculated as:

Frequency accuracy = signal generator accuracy + 1 ppm.

Amplitude accuracy = ± (0.5 dB + signal generator accuracy + mismatch error + cable loss).

Assuming the Agilent receiver and Agilent 8648B signal generator specifications, with nominal values of mismatch and cable losses of approximately 1 dB, you can expect:

•Frequency reading, approximately: Frequency selected ±450 kHz

•Amplitude reading, approximately: Amplitude selected ±2.5 dB

You can save the settings of the project (.spf file) at any time. If you experience measurement or configuration problems, you can refer to the settings shown in the corresponding verification test.

Passing the test

If the display shows a single spectral peak, and reports frequency and power levels that match the output of the signal generator, the system has passed the test.

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 tests, refer to “Troubleshooting your E6474A system" on page 102.
