PG runs under Normal Linux and it's pulses have almost NO jitter.
Please try pg35-bin-linux.zip
It includes mainly pg-linux-2.2.17, pg-linux-2.4.19 and setenv-pg.sh
setenv-pg.sh is for set CPU_CLOCK_HZ Environment

I used RT-Linux before.
If I make a application for other user under RT-Linux,
Other user must update user's Linux-kernel-version
to same my kernel-version.
I think it is not user-oriented, but maker-oriented.
So, I made PG under Normal Linux, and got good acuurate timing.
--
Merit is user can use the PG code partially
 in a user program where needs accurate timing.
Demerit is cannot stopped by ^C while generating a pulse portion.

Finally, I'm sorry my poor English.
Thank you.
