Response Example:
SYMMBITS 01-05-31 10:57:58
M SC1 COMPLD
"CLK-4:LMRTIE-1S,2.000000,COMPL,,,75-MIN"
"CLK-4:LMRTIE-1M,2.000000,COMPL,,,75-MIN"
"CLK-4:LMRTIE-15M,2.000000,COMPL,,,75-MIN"
"CLK-4:LMRTIE-30M,2.000000,COMPL,,,75-MIN"
"CLK-4:LMRTIE-1H,2.000000,COMPL,,,75-MIN"
"CLK-4:LMRTIE-2H,NA,NA,,,75-MIN"
"CLK-4:LMRTIE-8H,NA,NA,,,75-MIN"
"CLK-4:LMRTIE-24H,NA,NA,,,75-MIN"
;
The response in this example shows that LMRTIE data was collected over the past
75 minutes (known as measurement time) and LMRTIE values have been
calculated for observation times of 1 second, 1 minute, 15 minutes, 30 minutes, and
1 hour. The values for observation times 2, 8, and 24 hours are not yet available
because the system has not been running long enough to collect that data. They do
become available as the system continues to collect data.
Maximum Relative Time Interval Error
This measurement is displayed in nanoseconds and measures an input port’s
Maximum Relative Time Interval Error (MRTIE) at specific observation time
intervals. MRTIE is based on the maximum phase deviation over an interval of time.
MRTIE values from 1 second to 24 hour observation times are available every
15 minutes. The command format is:
RTRV-PM[-TSG]:[<tid>]:CLK-a:<ctag>::MRTIE;
Response Format:
<sid> <date> <time>
M <ctag> COMPLD
"CLK a-b:MRTIE-a,<monval>,<status>,,,<meas time>"...
;
The parameters displayed in the response are listed below.
Parameter Value Description
CLK-a a = 0 to 4 Input port number of Clock active card 555xx-01 (5 input)
a = 0 to 8 Input port number of Clock active card 555xx-02 (9 input)
