Active Near-Field Probes (ScanEM-C)

As an amplified EM field probe for a spectrum analyzer, ScanEM-C outperforms the passive probes. Each ScanEM-C probe has an amplifier built-in -- no external amplifier required.

Each ScanEM-C probe covers the entire bandwidth. With the wide frequency response and a built-in broadband amplifier you will be able to see even the weakest emission without a bench-full of equipment and a maze of cables.

Check the frequency responses of the ScanEM-C probes versus their passive counterparts and compare for yourself. Traditional passive probes have little or no output at lower frequencies (where the most fundamental frequencies are).

ScanEM-C can pinpoint a source of emission down to a trace or a specific component.

Even with the preamplifier, the passive probes produce little or no output at lower frequencies. This distorts the visible ratio between fundamental and harmonics.
