Maximum signal
strength:
Threshold level for maximum signal strength.
This is a measure of the stream signal power. It is expressed
according to the level mode selection made in the
Setup -
ETR
view:
dBm: in decibels relative to a reference value of
1
mW
dBuV: in decibels relative to a reference value of
1
µ V
dBmV: in decibels relative to a reference value of
1
mV
Maximum
frequency offset:
Threshold level for maximum centre frequency offset
The impulse response checking threshold values are only relevant when the probe is
licenced with the
Advanced RF Option
. Threshold values for each impulse will
become visible in the
COFDM - Impulse response
view as a highlighted box in the
impulse response graph. If an impulse peak does not fall within its box an alarm will be
raised. Threshold values for a maximum of ten impulses may be defined.
Impulse response checking:
Impulse detection
limit:
The impulse detection limit in dB. Signal peaks with lower
level than the detection limit will be regarded as noise and
not considered an impulse.
Enable:
It is possible to enable or disable time location and level
check of an impulse. Mark the 'Enable' check-box for the
probe to raise alarm if an impulse peak is not found within
the graph box defined by the specified time and power
limits.
Name:
A text string specified by the user to name an impulse.
Typically this will be the name of a transmitter.
Time min:
The minimum time an impulse should occur after the main
impulse
Time max:
The maximum time an impulse should occur after the main
impulse
Power min:
The minimum power of an impulse compared to the main
impulse (in dB)
Power max:
The maximum power of an impulse compared to the main
impulse (in dB)
