I want to take advantage of the topic just to ask if anybody has any
manual or schematics of the PTS 040. I realize that the PTS 160 is close
enough, taking in account the different frequency range, and they use
almost the same modules but it would be nice to have the right manual.
What is about the remote interface? Please, share the info.
Way back in the 80s, I used a PTS and the remote interface, so I'm going
off memory. As I recall, it's basically a BCD parallel thing with a
strobe. The general architecture of their synthesizers is a series of
decade modules, so the parallel interface just extends that to as many
digits as you have modules.
Settling time to the new frequency is pretty fast (<1 microsecond, I
think) but not necessarily phase continuous, and, there can be glitches
during the transition (i.e. if one module switches faster than the
others). no fancy-shmancy DDSes back in those days.
