Good point. I wasn't paying attention to the PPS only context in the
subject. I keep forgetting which way is best for PPS. Fortunately, all the
software I've used knows how to handle inverted PPS.

Hi Tom
I have collected the log from it. Log level is service. The 9.2G pll pass the
test today. The log during the power-up process is also included.

The MAX3223 chip does exactly what you need. It converts 3.3 volt serial
to RS232 levels.
You can buy just the chip and add a few passives to a perf board and make
what you need or buy a little PCB with the parts already soldered down like

I've used that sparkfun part to great success... Works like a charm. Highly
recommended!

Not likely.
The normal RS-232 level shifter chip includes an inverter. (No good reason,
just historical, but with a long history.)

Would this do the trick? -

Looks nice and it appears the unit is actually quite clean.
Looking forward to the 9815 porn. Better watch someone may be reading this.

I'm pleased to report this TIC is now running again (albeit with some
temporary hacks, such as a 7915 regulator).
There were a couple of dried-out electrolytics, the shorted series-pass
regulator referred to above, and an open-circuit 2N708 controlling the
timebase gating. Another 2N708 died when

Wow a poor mans test setup. Kind of my speed and no HPIB or big counters
etc. Like the re-use of Lady Heather. Clever.
OK now to go find the soldering Iron and hack my TBolt... Maybe not today.
So if you have a 5065 with 5 MHz out it needs to be doubled?
With respect to the cfield. Yes its pre
