Jitter - SDI in A [SDI Modes]
[PHQX01E / PHQX01E-IP / PHQXM-01E]
The jitter toolset is available on the ‘SDI In A’ BNC (the one with the red nut).
The jitter instrument shows automated measurements to SMPTE standards.
Readings for each of the filters are displayed as an overlay on the right hand side of the instrument.
Any red text displayed indicates an out of specification reading.
As with the Eye instrument, a submenu is available using the right-click on the mouse control:
l Scale > [sliding scale: Y graticule adjustment from +/- 0.2 UI to +/-8UI]
l Trigger > [None, Single Line, Two Lines, Single Field, Frame]
l Eye and jitter filter > [10Hz, 100Hz, 1kHz, 10kHz, 100kHz]
l Infinite Mode > [Enabled, Disabled]
l Jitter Color > Waveform color selection
Color selection is via a HSV tool providing two cursors. The left hand color rectangle allows
selection of hue (horizontal) and saturation (vertical). The right hand vertical bar selects color
lightness.
l Show jitter for unsupported rates > [Enabled, Disabled]
Trigger modes are useful for correlating jitter content to line and frame rate frequencies.
