Performance Monitoring
Measurement Properties
Individual Input Ports
To specify measurement properties for a single input port of a Clock card, the
command format is:
ED-SYNC[-TSG]:[<tid>]:CLK-a:<ctag>:::
<montype>=THR-a&CRI-a&RPT-a&PM-a&GOOD-a;
PM-a a = Y or N Automatically displays (Y) or does not
automatically display (N) each new
measurement as it occurs
GOOD-a a = 1 to 15 Number of consecutive good measurements that
must occur following a bad measurement before
an input signal can be qualified and for the
INMEAS event to be cleared
Parameter Value Variables Description
CLK-a a = 1 to 4 Input port number of Clock card. Applies to
monitored types other than SPRD.
<montype> FFOFF-a a = 3S, 12S, 48S,
192S, 768S, 3072S
FFOFF monitored type, where a is the averaging
time interval in seconds
LMRTIE-a a = 1S, 1M, 15M, 30M,
1H, 2H, 8H, 24H
LMRTIE monitored type, where a is the
observation time interval in seconds (S), minutes
(M), or hours (H)
MRTIE-a a = 1S, 1M, 15M, 30M,
1H, 2H, 8H, 24H
MRTIE monitored type, where a is the
observation time interval in seconds (S), minutes
(M), or hours (H)
SPRD-a a = 3S, 12S, 48S,
192S, 768S, 3072S
SPRD monitored type, where a is the averaging
time interval in seconds
TDEV-a a = 1S, 4S, 16S, 64S,
256S, 1024S
TDEV monitored type, where a is the averaging
time interval in seconds
TIE-a a = 1S, 1M, 15M, 30M,
1H, 2H, 8H, 24H
TIE monitored type, where a is the observation
time interval in seconds (S), minutes (M), or
hours (H)
THR-a a = 0 ns to 1,900,000,000 ns Threshold value, in nanoseconds, for LMRTIE
and MRTIE monitored types
a = 0 ppm to 7,300,000 ppm Threshold value, in ppm, for SPRD and FFOFF
monitored types
a = 0 ns to 800,000 ns Threshold value, in nanoseconds, for TDEV
monitored type
