A way to measure the delay between the PPS input pulse and the measurement latching is to use an
oscilloscope (or a time interval counter) connected as shown below. For this measurement, it is not
needed to connect an antenna to the PolaRx4TR. For easier interpretation of the results, cables C1 and
C2 should have the same length.
Before measuring the delay, the PolaRx4TR has to be configured to synchronize its PPS OUT signal
with the measurement latching epoch. This is done by setting the
TimeScale
argument of the
setPPSParameters
command to “
RxClock
”. You can do this using RxControl (go to the
Navigation > Receiver Operation > Timing
menu):
