Maximum Relative Time Interval Error
This measurement is displayed in ns 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 which will be 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)
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

type, where a is the observation time
interval (refer to Table H for details).
Variable a can also be appended to
MRTIE in RTRV-PM to obtain a response
for only that measurement time
