The following example sets the PPS on Slot 1, Port 2 to 1MPPS and the pulse width to
500nsec (1/2 the duty cycle).
ATS-6511>pps 1 2 1e-6 5e-7
The following rules apply:
1. PERIOD - period of pulse in seconds(max of 1, min of 1e-7)
2. WIDTH - pulse width in seconds (minimum of 5e-8)
3. For PPS Rates where the duty cycle is 10 µs or greater the pulse_width must be a
multiple of 10 µs, at least 10 µs wide, and at most half the duty cycle of the
pulse_period.
4. For PPS rates where half the duty cycle is less than 10 µs, the pulse_width must be
exactly one-half the pulse_period. (See example above.)
The system will generate an error message if the values are not correct or entered
improperly.
To verify the settings use the settings hardware:slots:N command (N=Slot #) to obtain
the current settings for a particular card.

IRIG: Valid DC IRIG Codes are A(000,003,007), B(000,003,007), D002, E002,
•
G002, and H002. Default is B000. To set the IRIG Code for the individual ports use the
irig command:
ATS-6511> irig [slot#] [port#] [Code A-H] [Code Format <NNN>]
The following example sets the IRIG for Slot 1, Port 3 to A 003.
