QuadStat
EA164
-
The QuadStat is a software-controlled four-channel potentiostat. Each channel can be used as a single three-electrode potentiostat. Alternatively two (bipotentiostat), three, or four working electrodes can be used in a single reaction chamber with a common reference and auxiliary electrode. Potential at each working electrode can be independently adjusted between 2.5 V, or by using an external waveform generator to between 10 V. The QuadStat can measure currents from pico- to milliamperes, making it ideal for amperometric biosensor research including use as a multichannel monitor for in vivo nitric oxide or dissolved oxgen sensors.

10 GHz Signal Source
YIG Series
-
The SC5503B and SC5502A are designed to meet demanding low phase noise applications. This is accomplished by employing a multiple phase-locked loop architecture as well as a YIG oscillator as the heart of its synthesizer. Frequency accuracy is provided by an onboard 10 MHz temperature compensated crystal oscillator (TCXO) which can be phase locked to an external reference source if required. These modules can be used as standalone CW signal sources or as LO sources for frequency conversion systems such as the SignalCore IQ modulators and demodulators. They are designed to meet the requirements of many modern applications such as wireless device testing, software-defined radio research, point-to-point radio, multi-channel coherent systems, and other academic and military programs.

Boundary-Scan DIMM Socket Tester
ScanDIMM
-
Maximizing test coverage is an important piece in test procedure development. Unfortunately, not all designs have the necessary requirements in place to accommodate boundary-scan test methods on memory devices. ScanDIMM digital socket test modules are designed to overcome such limitations when testing DIMM sockets utilizing boundary-scan test techniques.ScanDIMM modules provide the capability to instantly turn any DIMM socket into a fully compliant IEEE-1149.1 device. Integration is as simple as assigning the included BSDL file to the reference designator of the target socket and compiling test vectors.In multi-socket systems, multiple ScanDIMM modules can be linked to provide even greater boundary-scan test depth.

Total Sulfur Analyzer
Model T108
-
Teledyne Advanced Pollution Instrumentation
The Model T108 Total Sulfur analyzer is designed to measure mixed sulfur impurities, collectively referred to as Total Sulfides, in air or carbon dioxide gas. Since there is no scrubber in the system, the instrument reading is the sum of the oxidized sulfur compounds and SO2.The Model T108 consists of a modified Model T100 SO2 analyzer with special software and a Model 501TS high temperature thermal oxidizer. Sulfur compounds are heated as they pass through the converter and oxidized into SO2. When analyzing CO2, which generally contains no oxygen, approximately 6% O2 is added to the sample before entering the converter. This dilution is corrected in the calibration procedure.
