Wrong Jitter Value After a Certain Period for High PPS

[Gamze Nur Kaba]

After a certain time trex gives a same value for jitter (it gives 7 sometimes 8 or 9), this time period is related with pps value because if i give high pps like 10 Gpps it gives the wrong value(7) constantly to the terminal after 1 hour(for example) but if i give 1Mpps it gives this wrong jitter value after 3 hours(for example), the point in here is that this wrong jitter value is related with pps. If i give 100kpps for example, it doesn't give wrong jitter value it gives true jitter values to the terminal. What could be the reason of this error?
