Measurements
Table 4-4 lists MRTIE measurements and the measurement time period for an input
port.
Command Example:
RTRV-PM::CLK-4:SC1::MRTIE;
The response to the command in this example displays MRTIE 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
MRTIE-a a = 1S, 1M, 15M, 30M, 1H,
2H, 8H, 24H
Performance monitoring measurement type, where a is
the observation time interval (refer to Table 4-4 for
details). Variable a can also be appended to MRTIE 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 Averaging time calculation was completed
NA,NA Averaging 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.
