If I use a RadiSense 10 probe, do I still need to apply the X-Y-Z correction factors in the EMC test software?

No, this is not needed anymore! The RadiSense® 10 probe has the capability to store the x, y and z-axis frequency response correction data from an ISO17025 accredited calibration certificate internally inside the field probe as ‘user correction’. In this way you cannot make any mistakes like applying the wrong axis factors and/or forgetting to apply the corrections. As a result of this feature, you can achieve higher quality EMC testing.

How do I have to place the RadiSense probe in order to measure in Cartesian coordinates?

The RadiSense probe is always measuring in rectangular coordinates, since all three axis’ are orthogonally aligned. In theory it does not matter how the sensor is placed in the field, it should always indicate the same total E-field.

The total field is calculated by Etot = SQRT (Ex² + Ey² + Ez²).

Nevertheless, no E-field sensor is perfect due to probe shape, probe dimensions, field perturbation and anisotropy small errors will exist. Therefore, it is recommended to place one of the axis’ parallel to the field. This can be accomplished by placing the sensor in such a way that one element has the same direction as the elements of your radiating antenna.

What is frequency range of the RadiSense 10 probe?

The RadiSense 10 probe is available in two versions regarding frequency range. The models RSS2010H and RSS2010S have a frequency range from 20 MHz up to 10 GHz. The models RSS2010B and RSS2010I have a frequency range from 9 kHz up to 10 GHz. Within this frequency range the probe specifications are guaranteed. The RadiSense 10 models are all useable up to 12 GHz.  

When the RadiSense 10 probe needs ISO17025 calibration, is it required to send the RadiCentre + LPS2001B laser card together with the probe?

In case the calibration is being performed at DARE!! Calibrations (ISO107205 accredited of E-field probe calibrations) this is not needed. The calibration labs at DARE!! Calibrations are equipped with multiple RadiCentre + LPS2001B systems that can be used to operate the RadiSense 10 field probe during calibration. In this way the transportation costs and damage risks are minimized. The calibration results (frequency response X-Y-Z, linearity and isotropy) are provided as an ISO17025 calibration certificate (Adobe® PDF format) as well as in electronic format (MS® Excel file).
