Demodulator Status 
On CLI diag page 7.0 (Demodulator Status), verify that the applicable demodulators 
are locked and that the RS uncor Blks count is not incrementing. The following 
illustration shows demodulators 0-9 locked. 
 
Note: You must refresh the diag page manually to check for incrementing counters. 
If a demodulator is unlocked, verify that the output of Port 3 has the digital tier (564-
1002 MHz) set -6 dB from Channel 2. 
Important: Do not use the PwrLvl column on this page for absolute power 
measurements of any kind. Engineering has noted that a reading of < 29 dBmV 
indicates that an issue is present. 
Note: For additional information, see the CLI Diagnostics chapter of the Cisco DSAN
