Air Core Harmonic Filter Reactors
Use of nonlinear loads such as power electronics based equipment and electric furnaces have been on the rise for the last decades. Such loads decrease the power quality of the network that they are connected to. One of the most important parameters for defining the power quality is harmonic distortion.

High Impedance Active Probes
18C & 19C
High impedance probes, PICOPROBE® MODEL 18C and MODEL 19C, combine the most advanced MOS and bipolar technologies with special, low capacitance packaging techniques to achieve truly remarkable electronic measurement capabilities. While being manufactured each instrument is individually optimized for the best possible performance. The extremely low input capacitance, high input impedance, and almost negligible input leakage current permits the direct probing of even the most sensitive MOS dynamic nodes. At the same time, the full dc capability of this Picoprobe coupled with the high speed capability permits the full characterization of circuits.

High Impedance Active Probes
7
Designed as a companion probe to Models 12C and 18C for driving integrated circuit lines so the Model 12C and 18C can be used to measure the response of adjacent nodes. The Model 7 consists of a flexible 6 foot, 50 ohm coaxial cable accurately terminated to 50 ohms in order to avoid undesirable reflections. A special miniature connector receives replacement coaxial probe tips that provide a shielded environment to within 3 mm of the fine tungsten probe point, thus minimizing capacitive coupling to other parts of the circuit. The replaceable coaxial probe tips are offered in various point sizes and can also be bent to any shape in order to accommodate a variety of probing geometries.

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.
