Vibration testing of APIC Corp.’s integrated 20 GHz Micro Analog Transmitter (MicroATx). The MicroATx is a high-fidelity broadband optical transmitter that converts electrical signals up to 20 GHz RF into a low noise, high dynamic range optical signal for transmission through fiber up to 25 km. The transmitter was tested for operation during vibration, mechanical shock, and reduced and elevated barometric pressure in accordance with MIL-STD-810G. It was also tested for electromagnetic emission and susceptibility in accordance with MIL-STD-461G, RE101, RE102, RS101, and RS103 to demonstrate non-interference of other co-located hardware and non- susceptibility to high ambient electrical and magnetic fields.
