Data Sheet
Frequency Response Measurement Input Selections (Option SD and HD)
Noise Spectrum Display (Option SD and HD)
V Sync Display (Option SD and HD)
H Sync Jitter and Wander Display (Option SD and HD)
Spatial Distortion Display (Option SD and HD)
New Measurements on V3.X – Options for SD and HD on V3.X offer the
three new measurements. The V Sync measurement will support the
complete video timing measurement along with the H Sync measurement.
The H Sync Jitter measurement measures the RMS Jitter and Frequency
Offset and Frequency Drift Rate for wander measurement that support IEEE
1521-2003. The user-definable demarcation frequency and Probability/Jitter
readout help to search for the root cause during debugging. The spatial
distortion measurement measures the size of the video image and detects if
any offset or cropping has occurred to the image. This is useful for design
engineers to ensure that their video processing is not deforming the picture.
This is also good for verifying video aspect ratio mixes such as letterbox
or side-panel modes.
