Why does the status light of the 8662 blink?
The 8662A monitors its operational status constantly. Any abnormal status results in a flashing status light. The most common cause of a status light is the 8662A set to EXTERNAL REFERENCE, with no 10MHz reference signal applied to the rear panel REF IN connector. After the condition has been corrected, pressing the status key once will clear the message.
