All Input Ports
To specify measurement properties for all input ports of a Clock card, the command
format is:
ED-EQPT[-TSG]:[<tid>]:CLK0&&a:<ctag>:::<montype>=THR-a&RPT-a&PM-
a&GOOD-a;
a = 4 if Clock card is 555xx-01 (5 input)
or
a = 8 if Clock card is 555xx-02 (9 input)
Command Example:
ED-SYNC::CLK-0&&8:SC3:::TDEV-1s=THR-10;
Response Example:
SYMMBITS 01-06-01 10:25:04
M SC3 COMPLD
;

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
RPT-a a = Y or N Indicates if an event is generated (Y) or not
generated (N) when a threshold is crossed
