Analyzing a Signal
Analyze Mode may be selected with the Analyze key at any time. In
this mode, the instrument attempts to lock onto the digital video sig-
nal and, if successful, analyzes the status of the various signal char-
acteristics at one instant in time and reports the status to the Review
List. The Review List may be viewed on the OSD (on an attached
video monitor) as well as on the SDA 601 LCD when no menu is
active. The up and down arrow keys scroll through the list of de-
tected “conditions.”
The conditions detected and reported in an SDA 601 analysis are:
Video format TRS (OK/incorrect)
Line standard (625 or 525) ANC Format (OK/incorrect)
Video present or missing Zero length ANC (yes/no)
Video resolution (8 or 10 bits) APCRC changes (yes/no)
EDH packet found/missing FFCRC changes (yes/no)
Audio status (16 channels) APCRC errors (yes/no)
Stuck bits (if any) FFCRC errors (yes/no)
