4. Press the CURSOR button to display the measurement cursors.
5. Position the first timing cursor at the left edge of the zero-crossing point of
the Eye waveform. (See Figure 69.)
NOTE.
If necessary, use the Gain and Sweep controls for better vertical and
horizontal resolution. (See page 105, Gain, sweep, and magnification.)
6. Position the second timing cursor at the right edge of the zero-crossing point
of the Eye waveform. (See Figure 69.)
7. Check that the Delta readout is less than the following: (See Figure 69.)
SD Signals (per SMPTE 259M)
Timing jitter (10 Hz filter): 740 ps (0.2 unit intervals).
Alignment jitter (1 kHz filter): 740 ps (0.2 unit intervals).
HD Signals (per SMPTE 292M)
Timing jitter (10 Hz filter): 673 ps (1.0 unit intervals).
Alignment jitter (100 kHz filter): 134 ps (0.2 unit intervals).
3 Gb/s Signals (per SMPTE 425M)
Timing jitter (10 Hz filter): 336 ps (1.0 unit intervals).
Alignment jitter (100 kHz filter): 67 ps (0.2 unit intervals).
