7. BIT
The SR sensor includes a built-in test feature. This feature is designed to allow operators to
identify HW or other faults that might result in reduced sensor performance or even prevent
operation of the sensor.
Note – The BIT feature is not support in all FW versions. In order to find out whether your
sensor support BIT please contact Magos support team.
7.1 BIT M
The built-in test contains 2 types of tests – continuous and periodic. Continuous tests are
run continuously. If the test fails BIT status is immediately reported. Periodic tests run
periodically (approx. once per minute).
In any event, regardless of test results, a BIT status report is sent periodically upon
completion of all periodic tests.
While all tests have a "Boolean" "Pass/Fail" result, most tests also report a numeric test
result if relevant.
To find out how to access the BIT status report, and depending on the control software you
use, please see:

7.2 BIT D
The following built-in tests are included in the SR Radar:
Jamming – Radar SW suspects a jamming attempt / an external interference. This test is run
●
continuously and any suspected jamming/interference is immediately reported. 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.
