BERT Measurement Solutions
Bit error rate testers (BERTs) are usually the initial step for communications testing. These instruments generate digital test patterns, typically pseudorandom binary sequences (PRBSs), that drive devices under test (DUTs). Following the transmission of the signal through the link, the receiver in the BERT captures the signal. This setup can be used for multiple testing purposes, such as to evaluate the performance of a transmitter, a receiver, or an optical link.

Binary BCD Converters
Computer Conversions Corporation
The BCD Series of BCD to Binary Converters will convert 4 digits of scaled BCD angle data with a full scale of 359.9degrees into 12 Bits of binary angle data (MSB=180degrees). These units are entirely digital, require no timing or control signals and do this conversion in less than 500 nano-seconds. Logic levels are TTL/DTL compatable and +5V DC power is required. They are packaged in a 2.6 x 3.1 x .82" H PC board mounting module.

Protein Sequencer
PPSQ-51A/53A
The PPSQ is an instrument for determining the amino acid sequences of proteins and peptides, which combines an Edman reaction section with a high performance liquid chromatograph (HPLC). There are 2 types: the PPSQ-51A, which is equipped with one reactor, and the PPSQ-53A, which is equipped with three reactors. On the PPSQ-53A, the continuous analysis of the amino acid sequences of multiple samples can be performed one after another. In the Edman reaction section, amino acids are cleaved in order from the N-terminal of a protein by repeatedly performing Edman degradation, and are derivatized. As a result, stable PTH-amino acids are produced. The PTH-amino acids are injected online into the HPLC, and analysis is performed. The HPLC data is saved on the PC, and data processing software is used to process the chromatograms. Then, amino acid sequence estimation software is used to identify the amino acids and estimate the sequences.

Sequence of Events Recorder
SERNET
Each SERNET product can work as a stand-alone system monitoring up to 48 digital inputs or multiple SERNET units can be networked together to form a larger system with all events consolidated in one chronological list as they occur. A single WEB browser screen can display alarms from several SERNET units, making it easy to see the interaction between different equipment types or processes. This flexibility makes it easy to analyze alarms across an entire site or even across multiple sites for a larger system view - much better than piecing together a list of alarms from multiple devices.
