I reached out to SRS several months ago to inquire if the pulse width could be
configured from the default of 10 micro second. Their responses was no.

TAPR offers a FatPPS kit to stretch the pulse out, and it looks like
they're back in stock. I have one but haven't assembled it yet.

Hi,
20us length is a mil standard. Described in ICD-GPS-060.

Hi
One of the simplest justifications I can think of for a dirt cheap “Chinese”
digital ’scope is to capture short burst stuff like narrow pps pulses.
10 us / non-adjustable is a *very* common spec for a 1 PPS.

I've seen PPS ticks as short as 100 nsec from some equipment. Didn't think
to try the headphone
trick at the time, but am dubious about hearing pulses that short at
ordinary pulse amplitudes.

beautiful.
we should create a compendium: '101 uses for a dead cesium'

I did a similar thing with an HP5065A carcass, by repackaging the guts
of a Z3801A inside. Actually, I should say doing, rather than did - I
started this over ten years ago, getting only to the point where the
Z3801A was functional again. All the bells and whistles are in various
states of
Hi
If people are scrapping out 5065’s there just *might* be a few of us interested
in the various boards and modules that now are surplus to the “new” use. Contact
me off list. I’ll gladly pay shipping.

Well if anyone has the DC-DC converter from PRS50 that they've broken for
spares I'd be similarly very interested

I have found that a piezo sounder, a ceramic disk with two leads for making
beepers
works quite well for very short pulses.
For a very short period charge flows into this device, which is a capacitor,
and for that duration its dimensions are changed, and when it reverts to its
original state
Sorry Bob, but in my case, it was long ago, and the few unnecessary
5065A boards are long gone. The carcass I got had no Rb tube, and a
number of boards/modules were missing. I kept the power supply guts for
redesign, the front panel ass'y, digital clock, mechanical parts, and a
few odds and
Hi

Who knows, maybe all this talk has somebody else sending the
