Clock
Offset (ppm)
displays the positive or negative frequency offset
between the standard rate specification and the rate from the received
signal. The background color is used to indicate if the received clock
meets (green) or not (red) the standard rate specification.
Ext Clock Out
Note:
Available when the
Clock Mode
is set to
Internal
,
Recovered
, or
Backplane
. Not available on 8870.
Allows setting the clock that will be generated.
Interface Type
allows the selection of the clock interface:
None
(default when DS1 is not supported),
DS1
(default),
E1
, and
2MHz
(default for 88460). For eCPRI BERT the interface type is fixed to
None
.
Ext Clock Out
on a green background indicates that a valid clock is
generated on the clock port.
LOC
on a red background indicates that no clock is generated on the
clock port.
Connector
either indicates the connector type used for the clock or on
8880 allows the selection of
Bantam
or
RJ48C
when the BNC
connector is used by the test application.
LBO
(Line Build Out), available with DS1 only, allows the selection of
the interface Line Build Out that meets the interface requirements over
the full range of cable lengths:
DSX-1 (0-133 ft)
(default),
DSX-1 (133-266 ft)
,
DSX-1 (266-399 ft)
,
DSX-1 (399-533 ft)
, and
DSX-1 (533-655 ft)
.
