While playing with the RFTG-m GPSO I tried using a couple of RS-422 to RS-232
converters. These converters can be externally powered or "self-powered" by
the RS-232 signals.
Both units worked fine as long as the RFTG was only sending the 22 character
ASCII time code message once per second.
Hi Ed,
Looks kind of reasonable. Signal level and slow phase-drift can
illustrate some interesting properties which is sometimes hidden.
You have cross-talk and that can interact in interesting ways. You
mention low signal levels, and well, this would be consistent with that.
You should
The assumption is that you are using the time interval measurement or
phase measurement. The PM6681 datasheet says that the time interval
range is from 0ns and the phase range from -180 to 360 deg, usually it
is best to avoid the zero degrees zone. Say that your test is another
evidence that
