Figure 3.5 PTIMe:STAMp:FILT:PPSecond 1 Timing Example
3.5.17 PTIMe:STAMp:FILTer:1PPeriod <int> [1,604800]
The PTIMe:STAMp:FILTer:1PPeriod command is unrelated to OCXO disciplining. For more infor-
mation on OCXO disciplining, please refer to Section 3.6 .
This command specifies the maximum number of time-stamp pulses stored within one pulse period.
Only the first pulse time-stamp is stored and all other pulses will be ignored until the next pulse
period. This command will not be effective if the PPS filter setting described in Section 3.5.15 is dis-
abled. If this command is sent, then the limit of stored time-stamps specified in the
PTIMe:STAMp:FILTer:PPSecond command in Section 3.5.16 will be reset to one. The maximum
number of pulse period is one pulse every 604800 seconds (one pulse per week).
The following command will query the state of the PTIMe:STAMp:FILTer:1PPeriod command:
PTIMe:STAMp:FILTer:1PPeriod?
Below is an example of the results displayed for the PTIMe:STAMp:FILTer:1PPeriod 2 command. A
timing diagram for this example can be found in Figure 3.6.
(Since a period of 2 was sent in the command, only 1 pulse is stored every 2 seconds)
