Transmitted Jitter/Wander Amplitude Accuracy (Option A3K [A3Q])
10. Set the Spectrum Analyzer as follows:
Centre Frequency - 2048 kHz
Frequency Span - 25 kHz
Reference Level - 0 dBm
Sweep Time - 1.0 s
Video Bandwidth - 1 kHz
Resolution Bandwidth - 100Hz
11. Adjust the HP 37717C jitter amplitude until the second Bessel Null is observed
on the Spectrum Analyzer i.e second dip in the carrier level .
12. Ensure the Jitter amplitude displayed on the HP 37717C is between the minimum
and maximum limits given in Table 3-8.
13. Check the Jitter accuracy for each value in Table 3-8. In each case, set the HP
37717C Rate and Spectrum Analyzer Center Frequency to the value given in column
1 of the table (Set the HP 37717C PATTERN to ALL ONES and the jitter
AMPLITUDE to minimum after each change of Bit Rate). Set the HP 37717C
Jitter Modulation Frequency and Amplitude to the values given in columns 2 and 3
of the table. Fine-tune the amplitude to obtain the lowest carrier level on the Spectrum
Analyzer display and check that the jitter amplitude displayed on the HP 37717C is
between the limits given in columns 4 and 5 of Table 3-8.
