The ERS helps to eliminate the main cause of uncertainty (error) when measuring radiated emissions. These errors are entirely due to the reflections from any nearby metallic objects or surfaces. Also, the ground reflection is a source of error if not using a metallic ground plane and height scanning. Generally, these reflections will account for errors up to 20dB, far too much for compliance measurements.

By replacing the EUT with the ERS, performing a scan and comparing the results with the calibration data, the errors can be quantified and the results from the EUT adjusted accordingly.  This technique genarally reduces errors to around 6dB, comparable with test laboratory results.

Both standard and low output versions are given.

 

Model ERS-2

A low output version of the ERS with a field strength (at 3m) between 30 and 50dBuV/m (The equivalent figures for the standard version are 50-70BuV/m.

This lower output makes the ERS-2 ideal for use in test cells and chambers and other enclosed spaces, avoiding the tendency to overload the instrumentation.
