Dual Channel Bit Synchronizer for Rates up to 45 Mbps
LS-45-DB
The Lumistar LS-45-DB Dual Channel Bit Synchronizer Daughterboard provides optimal reconstruction of a serial PCM data stream that has been corrupted by noise, phase jitter, amplitude modulation, or base line variations. The all-digitaldesign assures a high performance, consistent product, with excellent reliability and long-term stability. Dual channel design can feed each channel of the LS-55-DD dual decom. The LS-45-DB also has a post D combiner that allows for optimal ratiocombining of the two input signals A unique Built-in-Test feature allows performance verification for the Bit Synchronizer to ensure the highest level of operation. Auto-test BIT is performed for a short duration on the application of power and tests more than 90% of the Bit Synchronizer components. This test verifies that power is properly applied, verifies that there are no internal bit errors, and performs other tests to ensure that the bit synchronizer is fully operational with status indication of results. Command-test BIT performs the same functions and can be initiated by the user at any time through the Lumistar software when used on Lumistar PC products. The user has the ability to generate internal pseudo-random patterns and calculate internal bit error rates with or without the injection of forced errors.Various status indicators are also available through the software. The Bit Synchronizer also contains a BER reader as well as frame sync pattern indicator.

Testing Released Water Vapor
Humiditest™ Complete System
The James Instruments Humitest System allows the concrete practitioner to monitor and ensure that a new structure is dry enough to proceed with the next phase of construction. This is especially critical for concrete structures requiring a coating, carpeting or similar floor or covering treatment. Installing such treatments before the concrete is sufficiently dry will typically cause expensive failures in the covering treatment. The only accurate way to ensure that the concrete is sufficiently dry enough to safely avoid expensive re-work is via a bore hole humidity test system, such as the Humitest System

Boxcar Averager
The Zurich Instruments Boxcar Averager operates as a high-speed digitizer synchronized to a reference oscillator that is phase-locked to the periodicity of the experiment. In the case of the laser repetition rate, for example, every data sample recorded at the input can be associated with the phase of the experiment and the signal components not synchronized with the experiment are strongly suppressed. The implementation based on an external reference signal removes the trigger jitter, and the digital realization enables a dead-time-free operation.
