Measure Timing Metrics of Periodic Signal
Measure the period, frequency, rise time, fall time, and duty cycle of a periodic signal. Also measure the delay of the input signal with respect to a reference signal
Open the model
time_metrics_measure. The model consists of a Timing Measurement block. A period sine wave of
50e6 Hz is applied at the reference input signal. A variable time delay of
1e-11 s is applied at the test input port. The Timing Measurement block is set to measure the period, frequency, 10%-90% rise time, 90%-10% fall time, duty cycle, and the delay with respect to the test input port.
model = 'time_metrics_measure'; open_system(model)
Run the model for
100 microseconds. The results are displayed on a Display block.
Period = 0.2 microseconds
Frequency = 50 MHz
Rise time = 5.903 nanoseconds
Fall time = 5.903 nanoseconds
Duty cycle = 0.5
Delay = 10 picoseconds
