reported. The jamming test also returns the estimated direction of the jamming
source and measurement standard deviation.
Current – Radar current consumption is too high/low. Test result includes current
•
measurement in mA. This test is periodic.
Vmain – The internal 5V DC supply output voltage exceeds limits. Test result
•
includes voltage measurement in mV. This test is periodic.
VextPOE – The main DC voltage supply input level exceeds limits. Test result
•
includes voltage measurement in mV. This test is periodic.
Temp. – The temperature exceeds operating limits. Test result includes temperature
•
measurement in ° Celsius. This test is periodic.
•
Vneg, Vhighh, Vpll, Vrf1, Vrf2, VpdPre, VpdCh0 - Various internal DC converter
voltages levels. These tests include voltage measurement in mV. This test is
periodic.
TxRfP – RF power detector places on the Tx output detects a power level that
•
exceeds limits. This test includes estimated power measurement in dBm. This test is
periodic.
PllLck – The Pll (in charge of generating the Tx RF signal) fails. This test does not
•
include additional results. This test is continuous.
TamperSw – Internal tamper switch has been activated. This means that the radar's
•
front cover (Radome) has been physically removed. This test is continuous.
Note I – This test is only support in specific HW models that include the Tamper
•
Switch. Contact Magos support to find out whether your unit includes this feature.
Note II – Once tamper switch is set it can only be cleared by an authorized Magos
•
technician.
Handling Failed BIT Reports
In case of a Jamming report – try to find out if there are any radio-emitting devices in the
vicinity of the radar (wireless communication equipment, nearby radars, etc.). Use the angle
measurement report to narrow down the emitting source possible locations.
In case of temperature – the sensor is designed to operate in extreme temperature
conditions from -40° up to +85° Celsius. If installed in a harsh environment that exceeds
these limits try to control temperature by shading/adding circulation (in case of
overheating) or adding an external heat source (even a lamp) in case of extremely low
temperatures.
In the case of tampered SW – this indicates that radar has physically tampered. Even if
tamper occurred due to an innocent mistake, once the Radome has been opened the unit
must be inspected by Magos personnel or an authorized technician to ensure that no lasting
damage has occurred.
In case of failure in all other tests, the unit must be inspected by Magos personnel or an
authorized technician in order to locate the HW fault and repair it.
