Performance Monitoring
Measurement Properties
Changing
Measurement properties can be specified for all input ports of a Clock card or a
single input port of a Clock card.
<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 type
a = 0 ns to 800,000 ns Threshold value, in nanoseconds, for TDEV
monitored type
CRI-a a = Y or N Indicates if an input port is qualified (Y) or
disqualified (N). Does not apply to SPRD
monitored type
RPT-a a = Y or N Indicates if an event is generated (Y) or not
generated (N) when a threshold is crossed
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
