• Propagation Delay Measurement

This mode is used to measure the time difference between

edges of two input channels:

TrigDelayCnt

Parameters for Propagation Delay Measure-

ment

For propagation delay measurement, the TIA counts edges

determined by the measurement mode for start channel

and stop channel, respectively.

In the above example, as

TrigDelayCntStart(1)

and

TrigDelayCntStop(2)

are specified, the TIA measures

the propagation delay from the first rising edge of the start

channel signal to the second rising edge of the stop

channel signal after the trigger.

Trigger Mode and Number of Measurements

The TIA starts the interval measurements when the speci-

fied edge (rising or falling edge) of the trigger is detected.

The TIA has two trigger modes the auto trigger mode and

the external trigger mode.
