Program Window “Statistics Channels”
To display the data of a particular channel, click the triangle
to the left of the channel.
If multiple channels are open, an additional click on the
channel information will bold the channel’s plotted data and
its statistical data.
The top five values are standard
statistical values

. The
numerical value “Edges per hour” is used to analyse the
number of steeply rising edges, spikes, peaks, pulses, sharp
bursts or high frequency transients of the field. The edge
thresholds can be defined in the “Channel” menu under “Set
edge criteria”. This is an experimental function. PLEASE
NOTE: If the 50 Hz high pass filter has been set with the help
of the configuration part of NFAsoft (maybe even as pre-
setting), this only applies to the channels “All3D”, “AllX”, “Al-
lY”, and “AllZ”. Nevertheless, possible frequency compo-
nents at 16.7 Hz will also be recorded in the correspondent
channel. In this case the sum of the frequency specific
channels may well be higher than that of “All3D”.
The light-blue field underneath the statistical channel data
represents the frequency distribution of the measured inten-
sities of the specific channel („
Histogram
“). It is self-scaling
and can be interpreted as follows:
On the left side of the x-axis a formula calculates and
plots how often the minimum value has occurred in a
given time interval, and similarly on the right side for the
maximum value.
The higher point marks the measured intensity - found
most often. The lower points indicate a specific value
very seldomly measured.

Edit
“Copy all“: Copies the plotted data area as well as the drop-
down of the “Statistics/Channels“ section into the buffer –
from here it can be inserted directly into your measurement
protocol at any point of your choice. This is similar to a
screen shot. All other edit options are self explanatory.

The 95th percentile is calculated heuristically. If the possible deviation
exceeds 10%, it will be noted in parenthesis after the figure in absolute
terms.
