Figure 6. A USB signal captured using laboratory equipment. Figure 7 is a typical example of a dataset saved by an oscilloscope (the exact format might differ but the given rules to import the data to LTspice will still apply). Figure 7. Raw data of the captured USB signal....
The trigger is a problem.Because I need to measure the period of signal(as I mentioned before,counting in a period of the signal by 200M clock ). I can't adjust the signal to a square wave with a low jitter. It confused me for a long time. Translate 0 Kudos Copy link Reply ...
Signal integrity is tested by observing the driver's differential output. Set the oscilloscope to look for trigger points between the 80mV and -400mV thresholds. (These thresholds are chosen because the receivers used in our testing have an input range of 20mV to -200mV, plus a ...
