This test checks the SD PIX MON output level into 75 8load.
Performance Requirement. This test verifies performance characteristics and is
listed in the test record.
1. Connect the SD video generator to INPUT B using a 75 8cable.
2. Set the SD video generator for a 525-format 100% color bars signal.
3. Connect the SD PIX MON output to the 75 8input of the test oscilloscope
using a 75 8cable. Use a 75 8-to-50 8adapter on the input of the test
oscilloscope if necessary.
4. Press the INPUT button and select Input B.
NOTE. A WFM7HD will report
I
unsupported standard
I
. This will not affect the
results of this check.
5. Measure the signal amplitude on the test oscilloscope. The following
substeps will help obtain a measurable display on the test oscilloscope. Note
this measurement.
a. Ensure that the termination is correct on the test oscilloscope. Use a
converter if necessary.
