AN-6130PCIe
HOLT INTEGRATED CIRCUITS
22
This is the waveform with an external RT responding through a MIL-STD-1553 bus coupler. The RT
amplitude is reduced approximately 75% by bus impedance transformation since RT transmit occurs on
a different bus stub.
RT1 Demo
If an external RT is not immediately available, on-chip RT1 can be enabled in the HI-6130 by entering
command B. The waveform below shows the HI-6130 RT1 responding to BC command with matching
address. The bus output should be terminated with 70 ohms and the RT response data shows same
amplitude as BC since RT transmission occurs on the same bus stub as BC transmission.
