Symptom
Possible
Cause
Solution
BDA will not turn on
when voltage is
applied
Connector Wiring
Ensure proper connections are made to wiring
harness.
Consult wiring diagram on product's spec sheet
Supply Voltage Range
Exceeded
Ensure power supply output is set to acceptable
voltage range.
Consult spec sheet for operating voltage range
Power Supply Current
Insufficient
Ensure power supply is capable of supplying at least
1.5x the expected current draw of the amplifier. This
is due to the inrush current of the unit as it powers
on
BDA powers down
after some time,
then turns back on
shortly after
Over-Temperature
Protection being
triggered. Amplifier
exceeding
recommended operating
temperature
Ensure sufficient heatsinking has been applied to
unit. Add or increase airflow to heatsink
Intermittent or non-
existent data link
Improper wiring harness
connections
Refer to section 3.1 and verify that the proper
connections have been made between the SC4200
and Triad BDA wiring harnesses
Improper RF
connections
Refer to section 3.2 and verify that the proper RF
connections have been made between the SC4200
and Triad BDA

than desired.
Excess radio output
power - EVM too high
Reduce radio output power in 0.5 dB steps until data
rate improves.
