EXT time-stamp: 2059, 518862.999999977 (last received pulse)
EXT time-stamp: 2059, 518863.000000227 (an incoming pulse that will be filtered)
When the PPS filter is enabled, the unit will only store M pulses every N seconds. The variable M is
the stored pulses per second limit specified with the PTIMe:STAMp:FILTer:PPSecond command
found in Section
3.5.16 . Variable N is the stored pulse period limit specified with the
PTIMe:STAMp:FILTer:1PPeriod command found in Section 3.5.17 . By default, variable M is set to
1 and variable N is set to 1 so only the first pulse will be stored every one second (1PPS) if the PPS
filter is enabled. Please refer to Section
3.5.16 and Section 3.5.17 for timing examples.
The following command will query the state of the PTIMe:STAMp:FILTer command:
PTIMe:STAMp:FILTer?
The following example command will enable REL, DUR, PPS filters all concurrently:
PTIMe:STAMp:FILTer REL DUR PPS
