A synchronous network traffic processor that synchronously processes, analyzes and generates data for high-speed network protocols, on a wire-speed, word-by-word basis. The synchronous network processor is protocol independent and may be programmed to convert protocols on the fly. An embodiment of the synchronous network processor described has a low gate count and can be easily implemented using programmable logic. An appropriately programmed synchronous network traffic processor may replace modules traditionally implemented with hard-wired logic or ASIC.

The present invention is a bit error rate tester that may operate on network paths having devices that add or drop idles within a transmitted bit sequence. In particular, the bit sequence determines whether a received bit sequence is synchronized. If the received sequence is not synchronized or if a certain event/threshold is reached, then the bit error rate tester re-synchronizes the sequence prior to analysis. Also, the bit error rate detector is able to operate on high-speed networks and provide bit granularity measurements.

A handheld optical unit is disclosed to measure optical characteristics of an optical input. A personal digital assistant is mounted to a housing to serve as a host computer for an optical spectrum analyzer disposed within the housing.

A data modifier including a trigger subsystem and a modification subsystem. The trigger subsystem generates a trigger signal when it detects the presence of a user predefined pattern in an input data stream. The modification subsystem responds to the trigger signal by altering user specified portions of a first input datum of the input data stream to create a corresponding output datum having a fixed, real-time delay with respect to the first input datum.
