Link Microtek has introduced an optical interface that enables high-speed
transfer of electromagnetic field measurements from a probe back to a PC
located up to 100m distant. Manufactured by Narda Safety Test Solutions,
the EMC-300 optical interface is suitable for applications such as EMC
immunity testing in an anechoic chamber, as well as TEM-cell and
stripline measurements. Designed for remote control from the PC via
standard fibre optic cables, the EMC-300 transmits measurement data for
display or storage at the PC.
Measurement range is 3kHz to 60GHz, depending on which of Narda's EMR
series isotropic field probes is used, and the field sampling rate is
38.4kHz. The instrument carries out simultaneous processing of
measurements for the X, Y and Z axes, and can display the sum of these
three inputs in various units. And thanks to features such as high
sensitivity, an auto-zero circuit and mains interference suppression
filter, the results are reliable and stable, even at low field strength
levels.
