Performance Monitoring
Measurements
The command format is:
RTRV-PM[-TSG]:[<tid>]:CLK-a:<ctag>::TIE;
Response Format:
<sid> <date> <time>
M <ctag> COMPLD
"CLK a-b:TIE-a,<monval>,<status>"...
;
The parameters displayed in the response are listed below.
Table 4-6 lists TIE measurements and the measurement time period for an input
port.
Parameter Value Description
CLK-a a = 0 to 4 Input port number of active Clock card 555xx-01 (5 input)
a = 0 to 8 Input port number of active Clock card 555xx-02 (9 input)
Parameter Value Description
CLK a-b a = 1 or 2 Clock card from which data was collected
b = 1 to 4 Input port number of Clock card from which data was
collected
TIE-a a = 1S, 1M, 15M, 30M,
1H, 2H, 8H, 24H
Performance monitoring measurement type, where a is the
observation time interval (refer to Table 4-6 for details).
Variable a can also be appended to TDEV in RTRV-PM to
obtain a response for only that measurement time
<monval> Calculated values for maximum phase variation of the input signal in nanoseconds
<status> COMPL Observation time calculation was completed
NA,NA Observation time calculation is not yet available
