Ionic Contamination Test Systems
CM+ Series
-
The Contaminometer (CM+ Series) system was originally developed by Protonique, the business of industry guru Brian Ellis. They also featured in the early development programmes of "cleanliness measurement" carried out by the US Department of Defense at China Lake in the 1970s. Historically, International Standard IPC-J-STD001 stated that assemblies be cleaned to a value of <1.5µg/cm2 of NaCl equivalence. However, the new design is linked to the introduction of the new process control metric introduced by Gen3 Systems: Process Ionic Contamination Testing. The CM+ Series measure the amount of ionic contamination in accordance with all existing test methods, often referred to as ROSE testing, as well as the new PICT test.

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.

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.
