Measurement methods
The SMP2 + any of the selective eld probe (WP400, WP400-3 or WPH-DC)
combination allows you to choose any of 3 measurement methods.
1. Broadband measurement
Broadband measurements may be made of the electric eld (E) and the
magnetic eld (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 eld intensity or magnetic ux 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 gure
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.
