6. FUNCTIONS
This section describes the main functions of the SMP3, in addition to
instantaneous measurement of the electromagnetic field.
6.1. Measurement modes
There are several working modes, depending
on the probe being used. All probes have
the time mode (6.1.1) with spatial average
(6.1.4), but only the WP10M, WP400,
WP400-3 and WPH-DC have the FFT
mode (6.1.2) and the Frequency Log mode
(6.1.3). For these
probes, on the main screen virtual menu you
can see the “MODE” function that allows you
to switch between modes:
• Time: Records changes in the total
field value over time (see section 6.1.1).
This mode can also be used to take
spatial measurements.
To do so, select the option in “MENU”
“MEASUREMENT OPTIONS” “Spatial
average” (see section 6.1.4).
• FFT: Frequency mode. The main screen
shows the spectral analysis (FFT) for the
selected span and the total field value
(see section 6.1.2).
• Freq log: Frequency log. Records
changes in the field level over time at a
specific frequency.
