For Frequency and MTIE measurements, you can set a threshold and fault mode for
each of three intervals (100, 1000, or 10000 seconds). If you do not define these
limits, they remain at the default values; see
Default Parameter Values
, on page
108. The MTIE and Frequency command syntax is described in
MTIE Command
,
on page 352, and
Frequency Command
, on page 348.
For example, you can assign a REPORT fault mode for a fractional frequency offset
exceeding 1 x 10E
–8
and a FAIL fault mode for an offset exceeding 1 x 10E
–7
. You
can specify an offset threshold for each time scale (T100, T1000, or T10000) for
both limits.

Note:
IGNORE or ALARM fault modes are the other settings for L1
and L2. For consistency, use L1 for the more extreme limit and fault
mode.
