Active near field probes

The CTK probes are powerful diagnostic tools that are an ideal complement to conventional EMC test equipment kits. Their high sensitivity and small tip size ensures accurate location of sources and tracks.The CTK kit comprises two probes, an E field and an H field. Both are self contained compact hand held probes which feature a very small sensing element, high gain amplifier and three outputs....- RF output for receiver or analyser- Audio output- visual (bargraph) output.The audio and visual outputs have a variable threshold control so that even a slight increase in field can cause a considerable change to the tone and display indication.The probes have a 'press-to-operate' push button switch so that if they are released, the power is automatically switched off to preserve battery life.A key characteristic is the flat frequency response. Traditional probes have little sensitivity at the lower end of the spectrum where most fundamentals lie. The flat frequency response of the CTK probes ensures that these lower frequency components are detected equally as strong as the high frequency components.
