Hi,
The J06 P-59992A time interval calibrator is not only there to calibrate
time offsets, but also offsets in trigger point. HP has a nice patent
which describes it all.
I also got one, found it on ebay.
Cheers,
Magnus

The simplest solution to the divider and clock shaper is perhaps to use an
LTC6954. The LTC6954 offers PECL/CMOS and LVDS outputs together with a low
jitter (sub ps) programmable (SPI) divider (1-63).A couple of coax relays like
those from Dow Key microwave together with some hardline and a coup

Good means whatever the 5313x needs for calibration. If that is four signals
that are
crossing zero within < 10 ps of the “correct time” then that is the definition
of good in this case.
Rise time delay, fall time delay are rarely the same in logic gates.

What does "good" mean?
I'd expect the variations due to power or temperature would be easy to
measure.
Delay through classic CMOS is linear with absolute temperatur
o I suspect that data will be forthcoming? :)
