CLO-10 Link Optimizer Revision 1
Front Panel Operation MN/CLO-10.IOM
CONFIG: Misc: Æ Reference (Reference Oscillator)
The CLO-10 can accept an externally supplied frequency reference, using the BNC connector on
the rear panel. However, rather than bypassing the internal reference and substituting the external
signal, the internal reference is used in a low-bandwidth (~ 2Hz) phase-locked loop (PLL); for
this reason, the CLO-10 actually phase locks to the external reference signal.
Edit the configuration and value of the frequency reference. The value is changed using the
STarrow keys. Values of Internal 10 MHz, External 01 MHz, External 02 MHz, External
05 MHz, External 10 MHz and Auto are possible.
Once the configuration has been edited, the user should press
ENTER.
Auto will detect the following external frequency references: 01 MHz, 02 MHz, 05 MHz and 10 MHz.
If the external reference frequency is invalid or no external reference frequency is connected, then
Auto – XX will be displayed.
Four examples are shown below:
Frequency Reference: ▲ ▼
Internal 10 MHz (ENT)
Frequency Reference: ▲ ▼
External 05 MHz (ENT)
Ext Reference Auto Det
Auto - 05 MHz
Ext Reference Auto Det
Auto - XX
CONFIG: Misc: Æ Redundancy
The CLO-10 can be optionally configured to operate within 1:1 through 1:12 redundancy
configurations. Refer to
Appendix A. REDUNDANCY SYSTEM OPERATION for detailed
information on the front panel operations associated with redundancy.
