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
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 117. If you experience
problems in setting up the tests, refer to “Solving Problems with
Your System" on page 130.
NOTE
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.
