Jitter insertion

The pattern generator can be ordered with built-in jitter options. The PPG3200 series are available with Option LFJIT and Option HFJIT; the PPG1600 and PPG3000 series are available with Option HFJIT only. The jitter insertion is the delay modulation of the data channels. Option HFJIT applies to each channel individually; Option LFJIT applies equally to clock and data.

The specifications below apply when the data rate equals the internal clock rate frequency of 20 to 40 GHz. For each frequency octave below, the internal clock rate, the specifications below will be reduced by half. For example, when the data rate is 8 to 15.99999 Gb/s, the values below will be divided by 2. When the data rate is 4 to 7.99999 Gb/s, the values will be divided by 4.
