Are DVD lasers faster?

These are my opinions. I hate spam.

There is a module in the ntp package/collection that puts out IRIG from the
system clock. You can use NTP if you want to keep
If you can snag something that will put out IRIG-B, there are lots of choices.
I’m still hunting for something that will take NTP in and put IRIG out. There
is probably someone doing it with a Pi or an Arduino.

I've been told that CD player type diodes can be successfully modulated
up to about 600 MHz, but that going much further is either difficult or
perhaps impossible. This came from a guy (at Tektronix) who worked with
various types
of diode lasers a lot, back in the 1980's. But at least they are

Before getting too excited about the various 8140 module designs, it may
be worth reflecting that the performance of the 8140 system is mediocre
at best from a time-nuts
Maybe not exactly, but I use an app on an old Android cell phone as my UTC wall
clock. Large characters in horizontal mode; NTP via WiFi.

Hi
I think this is one of those really small market items. You can probably cobble
one
together from bits and pieces for less than you can buy a good one.

I'd hoped that ebay or aliexpress would yield a bounty given how seemingly
simple these are, but I'm drawing a blank (and finding a lot of $300+ new
options). Anyone have a favorite source for either flat wall-mount or
rackmount displays that will pull from an NTP/SNTP/whatever server?

Hehe. Same here. When I looked into CPT I thought
Hi Bob & Julien,
Why bother with the short on the downstream end of that DC-blocking
attenuator? At 10 MHz I'd expect
leakage radiation to be negligible.

Hello,
I am a new subscriber to the list ! I am located in France and I play with
time and frequency instruments on my free time.
Recently I've bought an used FS725 unit with a PRS10 oscillator in it. I
was wondering how can I estimated the age of the Rubidium oscillator. I
think the age is
Hi Julien,
Earlier replies that discussed removing the DC supply from the 8140 outputs
gave me the impression your requirement was to connect directly the outputs of

recent suggestion of a series capacitor, but can
Hi,
All I have seen so far is an ADEV plot, and that is not a good tool to
estimate such systematics in. I would like to see the phase & frequency
data, it would probably be better for this type of diagnostics.
Do we have the raw measurements in a readable format?
Cheers,
Magnus

Hi
I’d say both have a “something” with a period of roughly 18 to 20 hours in their
data runs.

Hi
I think you would find a *lot* of smaller outfits “back in the day” running
hand soldering lines. Small scale wave solder for through hole did not
catch on the way reflow has for SMT. Dip solder was a rare item ….

I'm somewhat tempted to take the schematic and see if I can fit it in
the comparatively tiny Pomona boxes, although I have far too many side
projects already, enough 10MHz taps, and I still need to do the terminators.
The VersaTaps are supposed to be an actual synthesizer IIRC.

I had a look at Luciano's data and it's probably safe to say, that
the instability of the super-5065 would be the limit. The unmodified
