Measurement methods

The

SMP2

+ any of the selective field probe (

WP400

WP400-3

WPH-DC

)

combination allows you to choose any of 3 measurement methods.

1. Broadband measurement

Broadband measurements may be made of the electric field (E) and the

magnetic field (H). In this case, the device takes the full spectrum into account,

measuring all the energy present within the 1 Hz to 400 kHz frequency range

range (up to 40 kHz for the

WPH-DC

probe). The result is a single value in

units of electric field intensity or magnetic flux density, for aggregate exposure

across the full range.

The “MEASUREMENT OPTIONS” menu is used to select the measurement time,

the log interval, the average interval and the average type, as shown in the figure

below (screenshot 1A). Please note that the average interval is not an important

parameter in low frequency as limits are based on instant values.

Spatial averages may also be made using the “Spatial average” option.
