related to data acquisition.
5.4.1.
General
Here you can modify the
Name
(ID) of the SB (by default mr3000, followed by a dash and the serial
number UID of the SB) and the
Comment
string.
The
Name
may be used as the root-directory for the FTP service. No special characters and
no spaces are allowed for the
Name.
The
Name
is written in the Header of each XMR /
BMR file.
The
Comment
string should describe the location of the SB. It is intended to be included in
the alarm messages. Special characters are allowed.
Figure 5.4.1. Subsection dedicated to general information about the device.
5.4.2.
Acquisition
You may override the default setting for
Sampling
r
ate
and choose a higher sampling rate. You
may also record the unfiltered data – keep in mind that there is always an anti-aliasing filter, cutting
off the frequency contents above 80 % of Nyquist frequency (= half of the sampling rate).
NOTE
:
Higher sampling rates accumulate more data and create larger files.
In the MR3000SB there is a band-pass trigger filter on the data between 0.5 and 15 Hz. This
means that en event is created only if both the conditions are fulfilled:
•
the trigger level is exceeded;
•
the peak is associated to a frequency in the range 0.5 – 15 Hz.
NOTE
:
Values exceeding the trigger threshold do not necessarily lead to an event
creation.
