7.6 Dim (1D, 2D or 3D measurement) [Key 8]
The “Dim“ setting determines in how many dimensions magnetic field measurements
take place: 1-dimensional, 2-dimensional or 3-dimensional (isotropic)
measurements are available. Naturally, measurements will be slower in 2D or 3D
as the number of sweeps (and therefore the total sweep time) necessary to complete
a measurement increases 2- or 3-fold. However, units equipped with DDC
(Option 005) will be as fast in 2D as in 1D mode, as two channels can be used
simultaneously. Likewise, in 3D mode, sweep time is only double the normal
sweep time instead of triple without DDC.
Further related information can be found in “Measurement in 1D, 2D or 3D“.
7.7 VBW (Video filter)
The so-called Video filter is intended for optical smoothing of the signal. The
lower the Video filter setting, the broader and “smoother” the display of the signal
becomes. Using this filter, you can mostly suppress unwanted noisefloors,
harmonics or sporadic peaks. However, with a low Video filter setting, the display
can become less meaningful. In our example, there might be three separate
signals present. However, the low video filter straightens these signals out
to become one single “smooth” signal. The alleged noise band around the signal
has also been “smoothed out”. Thus, when dealing with weak signals, the
Video filter should be used only at a higher setting.
VBW=3Hz
VBW=300Hz
7.8 SpTime (Sampletime) [Key 6]
Determines the time per sample. As a single sweep consists of several samples,
total sweep time amounts to a multiple of the sampletime. The higher the
sampletime setting, the more accurate the measurement, however, the longer
it will take, too. You can enter values either in mS (milliseconds) or S
(seconds). Possible values range from 0.001 to 999.9. The longer the
Sampletime, the more accurate the measurement.
Please note: The maximum usable sampletime in DFT mode is 5s. The
maximum sampletime in non DFT-mode is 240s.
