Energy Probes
RjP-700 Series
The RjP-700 Series probes are designed to measure lower pulse repetition rate, longer duration pulses - up to 1msec pulse width at a maximum rep rate of 40Hz. This allows for measurement of pulsed flashlamps and other sources not possible with other probes. The combination of large area detector surface and long pulse width allow for measurements up to several Joules total energy. Integrated preamplifiers allow for longer probe-to-instrument cable runs, useful for manufacturing environments.

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.
