Performance Tests
Transmitted Jitter Amplitude Accuracy (Option UHK)
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 3-6.
