Multiplexed Amplifier-per-Channel Function Card
-
Multiplexed amplifier-per-channel systems have a dedicated pre-amplifier for every channel and a single Analog to Digital Converter, ADC, for the system. Amplified and filtered analog signals are multiplexed to a post-amplifier and then presented to the ADC to be digitized. Significant benefits of the multiplexed amplifier-per-channel system are: Higher Throughput Rates, Improved Filtering, Higher Per Channel Sampling Rate, Sensor Isolation, Improved Channel-To-Channel Isolation

Acoustic Emission Sensors
-
Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic acoustic waves generated in the material (e.g. elastic waves occur when a material cracks, wears, deforms, or corrodes) to electrical signals. The electrical signals are then amplified and filtered by a preamplifier and then transmitted to a special acoustic emission acquisition instrument for further data processing and analysis.

Active Loop Antenna
AL-130R
-
Also known as Magnetic Loop Antenna, the AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. It is a compact controller which can be used to enable/ disable RF measurement circuit and monitor saturation and battery low conditions remotely via a fiber optic cable up to 30 mtrs in length.
