2. The simplest way to measure jitter 1s to use the jitter readout and jitter thermometer in the Eye display or SDI Status display These are derived from the jitter waveform For more qualitative jitter information use the Eye and Jitter displays to view the presence and magnitude of jitter and its potential for causing data errors as the eye closes The Jitter display provides further analysis information including added time domain information such as the wave shape of the jitter and whether there are jitter components that are synchronous or nearly synchronous to the video line or frame these components appear as stationary or near stationary artifacts in line or field sweeps Looking at jitter in both displays can help you separate jitter sources to determine whether they are within a single circuit on a circuit board or from various pieces of equipment in a system If you are planning a composite D A conversion select the 10 Hz bandwidth filter to measure total broadband jitter Following is an example displaying a signal with a lot of jitter See Figure 55 on page 110 In the top two tiles the high pass filter is set for 10 Hz so that all jitter above 10 Hz is displayed In the lower two tiles the high pass filter is set for 100 Hz removing most of the 30 Hz jitter and leaving the spikes Both Jitter displays are set for two field sweep The upper Eye display shows a fairly even jitter spread which suggests a moderately uniform statist
