Valid PPS settings are 1, 10, 100, 1K, 10K, 100K, and 1M PPS. To set the PPS signal parameters
use the
pps
command:
ATS-6501> pps [slot#] [port#] [pulse period] [pulse width]
The following example sets the PPS on Slot 1, Port 2 to 1MPPS and the pulse width to 500 ns
(1/2 the duty cycle).
ATS-6501>pps 1 2 1e-6 5e-7
[OK] 2013-08-05T15:52:31Z
The following rules apply:
1.
PERIOD - period of pulse in seconds(max of 1, min of 1e-6)
2.
WIDTH - pulse width in seconds (minimum of 5e-7)
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.
Usage: <slot#> <port#> <pulse period> <pulse width>

To verify the settings use the
settings hardware:slots:N
command (where N=Slot #) to obtain the
current settings for a particular card.
