RF-H2 Monitor test (Tuner-1 Tuner-2)
An RF combined signal with one or more frequencies are applied to the tuner1 and/or tuner2 RF inputs. One carrier RF
level will be varied to test the alarms the other ones will be used to fill the scanning list. We have used 100.80MHz (RF
sweeping) and 100.50MHz(RF stable).
By slowly changing the the RF levels (in compatible way with the Validation and Hold time chosen) around the test zone,
wait for the alarms and go back up to the starting point.
Tested in Static mode first.
In static mode the alarm rises up after the validation time, a trap will be sent when the status variable changes but with
the time and the RF value of the first sample out of the range. When the RF level is lower or equal to THR- Hysteresis,
the status alarm after the hold time comes back to the (ok) state and another trap will be sent with the RF value and the
time of the first valid sample.
We have tested in static mode with the following values:
Thr: +110dBuV, Hyst: +3dBuV, Validation:2sec, Hold:2Sec
Thr: +110dBuV, Hyst: +3dBuV, Validation:20sec, Hold:10Sec
Thr: +110dBuV, Hyst: +3dBuV, Validation:180sec, Hold:60Sec
The behavior observed has been compatible with the definition with an accuracy error on the measure of about 2 dBuV
and timing errors of about 1-2 seconds
Typical Accuracy and Precision expected in general:
Min RF value readable : -6 dBuV, Max RF value readable: +123 dBuV
Accuracy: +-3 dBuV, Precision +-2 dBuV (Range -6 dBuV to +19 dBuV)
Accuracy: +-2 dBuV, Precision +-1 dBuV (Range +20 dBuV to +79 dBuV)
Accuracy: +-3 dBuV, Precision +-3 dBuV (Range +80 dBuV to +123 dBuV)
Under the alarm condition the RF alarm led on the panel must be on (not flashing) and clicking on the channel number of
the correspondent tuner the RF erro
r will be displayed. (“RF_LEV_H2”)
