11.7 Propagation Delay Test (PDL)
Run the Propagation Delay Measurement application to measure the round trip loopback delay around the IEEE C37.94
circuit.
PDL has two operating modes which differ in precision and refreshing intervals.
• Continuous: data is sent continuously, measurement precision is 125 µs.
• Ping Mode: data is sent and the round trip delay measured once per
second.
