Running the Pixel Error test
If your source device does not have the Quantum Data BCM pseudo-random noise
algorithm you can test the signal quality with the Pixel Error test. During the Pixel Error
test, the Analyzer captures an external, still-frame image (reference frame) typically from
the device under test and verifies that all pixels match over a user-specified number of
successive frames. The results are output to the generator’s display and can be issued as
a report.
You can also capture a reference frame from another device (i.e. other than the device
under test) and use that to compare with the frames from the device under test. This
enables you to obtain valid results if you suspect that the device under test cannot produce
an error-free reference frame. By using a reference frame from a known good source you
are assured that the test results are viable.
