Transmitted Jitter Amplitude Accuracy (Option UHK)
2. Select TRANSMITTER OUTPUT
SETTINGS [JITTER] and setup the
display as shown opposite.
3. 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
4. Connect up the equipment as shown in Figure 3-44.

5. Adjust the HP 37717C jitter amplitude until the first Bessel Null is observed on
the Spectrum Analyzer i.e first dip in the carrier level. (As an example, Figure 3-45
shows the first Bessell Null for 34MHz.)
6. Ensure the Jitter amplitude displayed on the HP 37717C is between the minimum
and maximum limits given in Table 3-5.
