It has grown into new, seemingly huge proportions but it is not anything
new.
Back in 1992/1993 I had designed in a SCSI interface part from a
catalog (naive beginner), I think the firms was called Emulex
or something like that.
When I got the first version of the PCB I had already understood the
error I had made (the part had never been produced, not even in
prototype quantities I think); so I had to redesign the board with an
NCR53CF96, a real part...
The first unit ( http://tgi-sci.com/tgi/fr64.gif ) had a huge
230 megabytes of a 2.5\" SCSI HDD inside, which cost me a fortune
(no www to search for bargains, bought it from Apple at something
close to $1k IIRC). Shortly after magnetoresistive R/W heads came
into being, 2.5\" SCSI peaked at 810 MB and among other things made
life easier in terms of magnetic field interference compared to life
with inductive heads. And forced me into doing ATA, now SATA, into
further products...

Not even a block diagram, and big pictures of ballgrid array

ADCs... (after figuring out what GSPS stood for).

Not usable with that data.

But more and more integration indeed.

Too many pins... Maybe just for thermal...
My opinion dataheet written by complete electronics moron He

GSPS in capitals is the wrong notation for Gsamples/second.

What is the correct notation for giga samples/second?

I\'d go with Gsamples/s. In a sufficiently unambiguous context,
maybe GS/s will do. (They wouldn\'t be talking about the rate of
change of conductance in a treatise on ADCs, now, would they?)

\'Samples\' is the only unit without a universally accepted

Why is S not an accepted abbreviation for \"samples\"? Because it\'s

Oh, I understand it, but _I_ would write Gsamples/s, Msamples/s,
ksamples/s, etc. I\'m OK with \'S\' for \'samples\' if the context
makes it unambiguous, I already said. I\'m _not_ OK with \'S\' for
\'seconds\'. It should be lower case \'s\'.

HP should be stamped out altogether. Use kW.

You are trying to treat this as if it were something akin to SI units. It\'s nothing like that. It is just an abbreviation, in such common usage that no one with any experience at all should know the usage.

If you don\'t want to write what the rest of the world writes, that\'s fine, but don\'t expect to never have to read it. That\'s like wanting to hear \"get\" instead of \"git\". When I pay attention, it is surprising how few people say \"get\". I can say \"get\" all day long and others are not going to change.

I agree that HP can be abandoned without too much pain. I\'d like to see kWh go away, but would be replaced with Joules, a rather much smaller unit. I believe there are 3,600 J to a Wh, so 3.6e6 J to a kWh. Grid level values are often MWh which is 3.6e9 J. So J is not a convenient unit for electrical stuff. The battery in my car is nominally 360 MJ... I think. Did I do the conversion right? One of the nice features of kWh in my car, is the battery is 100 kWh, making the conversion to/from % rather easy.

Which car? I have the Tesla in the states (mostly at the airport) and a Kia in Puerto Rico. A BEV is not practical in Puerto Rico unless you charge at home and I\'m living in Airbnb until I decide where to buy. I\'m hoping I have some better choices by the time I\'m ready to buy a BEV in Puerto Rico.. Whatever it is, it has to be small. A big car in Puerto Rico is a PITA! They have narrow lanes and some roads are really narrow.

Boggling, but worthless, unless you have GHz bandwidth requirements
in addition to GHz carrier requirements. Aperture time being small
also gives you GHz noise capability... not sure it\'s worth examining all
the bits in that firehose of a bit stream.

So, how much data does a channel-plate multiplier and streak camera output,

Flyguy missed the point by a country mile. He doesn\'t miss many opportunities to remind us how dim and ill-informed he is, but this effort is more comical than most.

A channel plate multiplier and a streak camera do have a lot of bandwidth, but once you captured a screen\'s worth of data you have to scan the screen, and digitise and store the result before you can collect another. Unlike Flygyuy, I do know what they were, but I\'d have to do quite a bit of digging to find out how fast current versions (if they still exist) can collect data or transfer it into mass memory.

Cambridge Instruments did use a channel plate multiplier in the EBMF 10.5 electron beam microfabricator, but it was used as a thin electron multiplier.. It was bit faster than regular photomultiplier tubes but only because the electrons didn\'t have as far to go. The streak camera would have been the quick bit.

I can make a thousand such \"new parts\" per month, all better than anything

Cambridge Instruments did use a channel plate multiplier in the EBMF 10.5 electron beam microfabricator, but it was used as a thin electron multiplier. It was bit faster than regular photomultiplier tubes but only because the electrons didn\'t have as far to go. The streak camera would have been the quick bit.

Hey SNIPPERMAN, have you LOST YOUR MIND? You just responded to the WRONG GUY, you IDIOT!!!

Boggling, but worthless, unless you have GHz bandwidth requirements
in addition to GHz carrier requirements. Aperture time being small
also gives you GHz noise capability... not sure it\'s worth examining
all the bits in that firehose of a bit stream.

Nah, from that POV it\'s no worse than a wideband amplifier. You just
need to filter afterwards to select the desired bandwidth. It\'s an
advantage of very fast sampling that the quantization noise gets spread
out over a very wide bandwidth so that most of it gets filtered out.

The main issues with RF sampling are: (1) DSP complexity and (2) phase
noise. For a fixed-tuned or narrowband application, a single-conversion
superhet saves a lot of FPGA resources, clocking hardware, and RTL code.

There are quite a lot of software-defined radio (SDR) libraries out
there to reduce the coding burden, but you still need some reasonably
hairy-chested hardware to run them on.

So, how much data does a channel-plate multiplier and streak camera
output, per second? More, or less?

A lens will do Fourier transforms with aggregate bandwidths of 1E20 Hz
for a few bucks, if you can collect the data. (Say 300k pixels times 300
THz temporal bandwidth.) There\'s this little problem of collecting it
all, of course.
