The following parameters can be configured:
HF BROADBAND QUICK SET-UP
• Standard: List of preselected standards.
This will affect other parameters that will
not be editable. For example: if you choose
ICNIRP standard then all the parameters in
“MEASUREMENT BEHAVIOUR” section will
not be editable as they are defined by the
standard.
MEASUREMENT BEHAVIOUR
• Measurement time: allows to define a
maximum time for the measurement.
Available values are: not limited, 1 min, 5
min, 6 min, 10 min, 15 min, 30 min, 1 h, 1
day, or custom from 1 second to 100 hours.
• Log interval: used to select the time interval
for storage of data in memory (see section
6.1.1). A value will be stored every ‘Log
interval’ seconds (or minutes). The available
intervals are 0.5 s, 1 s, 5 s, 10 s, 15 s, 30 s, 1 min and 6 min. There are also
available intervals with low power mode of 1 min, 2.5 min and 6min to allow
for longer battery autonomy for all probes.
• Average type: two types of average are available, tumbling or sliding.
Tumbling averages are taken at fixed intervals, while sliding averages are
taken through sliding time window. By way of an example, imagine that we
choose an average interval of 10 s. Since the device takes 2 samples per
second, in those 10 seconds we will have 20 samples. In the case of tumbling
averaging, we will have an average of samples 1 to 20, another average of
samples 21 to 40, and so on. In the case of sliding averaging, we will have
continuous averages as the window advances over time. In other words, we
will have the same initial average with samples 1 to 20, but then immediately
afterwards we will have another with samples 2 to 21, then another with
samples 3 to 22, and so on.
