STCLive T&D , coordinated testing to another probe.
Answer: Check the time protocols on both units via the “rtrv-dat” command. Both units should use the same Time protocol – either PTP or NTP. If one unit is running with PTP and the other is running NTP, there will be a 100% loss of packets during the test. Or if one probe has NTP and the other has "none", the test will likewise fail.
