1PPS cable correction1PPS cable correction
Allows to set a correction value of the delay time in ns unit that is caused by
difference of 1PPS cable length.
In the measured phase error value, the phase error and the cable delay are
included.
The cable delay is caused by difference of cable length between ReferenceReference
1PPS Input1PPS Input and 1PPS Input1PPS Input.
To measure the phase error precisely, set the correction value to 1PPS cable1PPS cable
correctioncorrection.
When calculating the delay time from the cable length, it is recommendable to
use 5 ns/m as the conversion factor.
If the cable length of 1PPS Input1PPS Input is longer than one of Reference 1PPS InputReference 1PPS Input,
set a negative number as the correction value.
Phase errorPhase error is calculated by the measured phase error and 1PPS correction1PPS correction
valuevalue.
Other result parameters such as cTEcTE(constant Time Error) are calculated by
using the phase error after correction.
