SSMPRI (SSM Priority Grouping)
When in SSM mode, this keyword provides a means to select between different
inputs that all have the same SSM value. If multiple inputs have an identical SSM
value that is the lowest (numerically) and are equally qualified in SSM terms to be
the input, the SSMPRI provides a means to select one input over another.
The SSM selection process will always choose an input of the lowest valued
SSMPRI, but will not revert within the same SSMPRI value.
For example, the system would choose input 1 under the following conditions:
• inputs 1–4 are all qualified at CURRSSM=4,
• input 1 has SSMPRI of 2,
• inputs 2 and 3 have SSMPRI of 5, and
• input 4 has SSMPRI of 7.
If input 1 becomes disqualified, the system must select 2 or 3. If they are the same
and neither is the current input, the system selects the one with the lowest
PRIORITY value.
If input 2 also becomes disqualified, the system uses input 3. If input 2 becomes
requalified, the system remains on input 3 because inputs 2 and 3 have the same
SSMPRI. If input 1 becomes requalified, the system uses input 1 because it has a
lower SSMPRI.
The keyword format is:
SSMPRI=<value>
Command Example:
RTRV-SYNC::CLK-0:SC1643:::PARAMETER=SSMPRI;
Response Example:
SYMMBITS 00-06-18 12:05:43
M SC1643 COMPLD
"CLK-0::SSMPRI = 8"
;
Parameter Value Description
<value> 0 to 8 SSM priority
