Clock Synchronization
REF OUT/Ref Output
Note: REF OUT is only available with the FTB-8130, FTB-8130NGFTB-8130NGE,
and 8140 models. The REF OUT signal is automatically enabled on the REF
OUT port (SMA connector) when the laser of the 10G/11.3G port is turned
ON.
Configuration
³
Divider Ratio: Allows the selection of the transmit test clock divider.
Choices are 16, 32, and 64. The following table shows the
corresponding output frequency in MHz.
For OC-192/STM-64/OTU2/OTU1e/OTU2e/OTU1f/OTU2f
For OC-768/STM-256/OTU3, there is no clock divider. The clock output
frequency is set as follow.
Signal Analysis
³
Frequency (MHz): Displays the generated signal frequency in MHz.
³
Output Presence: Indicates the presence of a signal at the REF OUT
port (green) or not (gray).
