Performance Tests
10. Receiver Trace Noise
B/R Trace Noise Phase IF BW = 10 Hz
31.Press .
32.Press . Wait for the sweep to finish as
indicated by the Hld notation on the left side of the display.
33.Press .
34.Write the s. dev (standard deviation) value shown, which appears on the analyzer
display, on the performance test record.
B/R Trace Noise Magnitude IF BW = 10 Hz
35.Press .
36.Press . Wait for the sweep to finish as
indicated by the Hld notation on the left side of the display.
37.Press .
38.Write the s. dev (standard deviation) value shown, which appears on the analyzer
display, on the performance test record.
Option 006:
1. Disconnect the RF cable from input B, and connect it to input A.
2. Press .
3. Go back to “A/R Trace Noise Magnitude IF BW = 10 Hz” on page 2-39, and perform this
entire procedure again, starting with step 6. Record all values in the performance test
record for analyzers with Option 006.
In Case of Difficulty
1. Verify that the 50Ω type-N RF cables are in a good condition. If possible, try to rerun
this test with another set of RF cables.
2. Suspect the A10 digital IF board assembly.
