Two more items to get rid of.
HP 8590A SA. 10 KHz to 1.5 GHz, -115 dBm to +30 dBm. Very clean. The
screen has no burn-in and is very bright. It has the tilt handle, but
no front cover. Option 21 (GPIB) is installed.
HP 54522A scope. 2 GS/s, 500 MHz dual channel. Channel 2 has a bad
input
Hi All -- Sorry if this is off-topic, but you all have a lot of
experience with equipment. I just picked up a 6061A and I'm happy to say
it mostly works. But... at frequencies below 250 MHz, as the frequency
output is decreased, the level drops too, and starting from +12dBm

I suspect that even if the target system is a Raspberry PI the critical
point is the $17 price (including shipping).
For precise time frequency, I am surprised that cost is the first
consideration, unless you are buying more than a few units!
A few days ago, I took my collection of obsolete handheld GPS
receivers outside and turned them on, to let them find themselves and
collect new almanac data. Most of them probably hadn't been turned on
for 2 years or more. All of them eventually acquired satellites and
started navigating. The
Does anyone have experience with the Synergy SSR-6Tr and the fairly recent
Lotus based M12M. It sounds like both are plug and play replacements for the
Older M12M's. Both claim improved specs. Both my XLI and FEI Zyfer time and
freq rec's use versions of the M12. Does anyone want to weigh in on

The nice thing about measuring temperature via sonic measurements is that the

Hi
Newer is always better :)….
The real question is :
Did the guys who designed the the hardware and firmware in a 10, 20 or 30 year
old box optimize it so that a better GPS would improve the performance of the
box?
Put another way:

I ran across this very issue when trying to calibrate my barometer chip against
the NWS station located less than two miles away. Their numbers for millibars
and inches of mercury do not agree. I sent them an email and asked what was
going on. They said their instruments read out in
atmospheric pressure taken for a weather observation is measured in
millibars and respresents the barometric pressure at ground level at
that location. If the instrument is located somewhere besides ground
level it will be corrected to ground level.
The value given in inches of mercury is
