• tERR(3 per) fall (P8) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the
falling edges (negative pulses). It is set up to measure edges at intervals of 3. The minimum
value is measured as tERR(3per)fall, min reported in mUI and the maximum value is measured
as tERR(3per)fall, max reported in mUI.
• tERR(4 per) r (P9) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the
rising edges (positive pulses). It is set up to measure edges at intervals of 4. The minimum value
is measured as tERR(4per)rise, min reported in mUI and the maximum value is measured as
tERR(4per)rise, max reported in mUI.
• tERR(4 per) fall (P10) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the
falling edges (negative pulses). It is set up to measure edges at intervals of 4. The minimum
value is measured as tERR(4per)fall, min reported in mUI and the maximum value is measured
as tERR(4per)fall, max reported in mUI.
• tERR(5 per) r (P11) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the
rising edges (positive pulses). It is set up to measure edges at intervals of 5. The minimum value
is measured as tERR(5per)rise, min reported in mUI and the maximum value is measured as
tERR(5per)rise, max reported in mUI.
• tERR(5 per) fall (P12) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the
falling edges (negative pulses). It is set up to measure edges at intervals of 5. The minimum
value is measured as tERR(5per)fall, min reported in mUI and the maximum value is measured
as tERR(5per)fall, max reported in mUI.
