Performance Monitoring
Measurements
Table 4-3 lists LMRTIE measurements and the measurement time period for an
input port.
Command Example:
RTRV-PM::CLK-4:SC1::LMRTIE;
The response to the command in this example displays LMRTIE information about
input port 4.
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
LMRTIE-a a = 1S, 1M, 15M, 30M, 1H,
2H, 8H, 24H
Performance monitoring measurement type, where a is the
observation time interval (refer to Table 4-3 for details).
Variable a can also be appended to LMRTIE 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
<meas time> Measurement time in which data was collected. Once the measurement time reaches
24 h, data older than 24 h are lost as new data are collected.
