This test is to verify the CableCARD under test and “vendor XXX” hosts can successfully tune in the lowest EIA QAM channel requirement of 54MHz.
Refer to the NDS/Harmonic channel map for low frequency QAM channel.
Note: NDS/Harmonic configuration does not support low frequency QAM channel.
12.3.4.1Verify the ability of CableCARD under test, “vendor XXX” host combination to tune unencrypted QAM64.Tuning “vendor XXX” host to QAM64 multiplex and verify audio and video on TV.
12.3.5Upper Frequency Interoperability Test
This test is to verify the CableCARD under test and “vendor XXX” hosts can successfully tune in the upper most EIA QAM channel requirement of 860MHz. Refer to NDS/Harmonic channel map.
Note: NDS/Harmonic head-end configuration does not support upper frequency QAM channel.
12.3.5.1Verify the ability of CableCARD under test, “vendor XXX” host combination to tune unencrypted QAM64.Tuning “vendor XXX” host to QAM64 multiplex and verify audio and video on TV.
All tests in this section are to be performed with the assumption that the SCM/NDS CableCARD is being used to test interoperability with “vendor XXX” hosts on the Harmonic head-end network.
12.3.6.1Verify power level of the FDC channel between –15dBmV and +15dBmV. Set the FDC channel frequency between low FDC frequency range. (70MHz - 90MHz.) Verify FDC channel frequency on sprectrum analyzer.
12.3.6.2Authorize a SCM/NDS CableCARD “vendor XXX” host combination for an encrypted digital service through the Harmonic HE system. Verify the host can display the encrypted digital service.
12.3.6.3De-authorize a SCM/NDS CableCARD “vendor XXX” host combination for an encrypted digital service through the HARMONIC HE SYSTEM. Verify the host cannot display the encrypted digital service.
12.3.6.4Tune the SCM/NDS CableCARD, “vendor XXX” host combination to analog service. Send an EAS message from the Harmonic HE system and verify EAS message is displayed correctly on a TV.
12.3.6.5Tune the SCM/NDS CableCARD, “vendor XXX” host combination to unencrypted digital service. Send an EAS message from the Harmonic HE system and verify EAS message is displayed correctly on a TV.
12.3.6.6Change the FDC channel frequency between middle FDC frequency range. (90MHz - 110MHz.) Verify FDC channel frequency and power level on a spectrum analyzer. 12.3.6.7Authorize a SCM/NDS CableCARD “vendor XXX” host combination for an encrypted digital service through the HARMONIC HE SYSTEM. Verify the host can display the encrypted digital service.
12.3.6.8De-authorize a SCM/NDS CableCARD “vendor XXX” host combination for an encrypted digital service through the HARMONIC HE SYSTEM. Verify the host cannot display the encrypted digital service.
