@laptop2d it's not better with Keysight. "Hey you really appreciated using our free PC software to safe your oscilloscope pictures, didn't you? Guess what: with the latest update, you need to pay for it!" or "Hey, our oscilloscope is broken, and at some point the firmware will stop working. Uh, that happend outside the warranty? Well pay 3k for our screw up"

Yeah, when I was researching how to measure phase noise, it was very telling that I found a HP technical article on how to (using GPIB/HPIB) perform the measurement using a spectrum analyzer. The new spectrum analyzers will measure it directly, if you pay for the option.

And I used a Keithley 4200 that locked its hardware when it went out of cal

That one looks intresting:

cool!

hm, 1kv isolation on 4 channels scope, fascinating to just have a quick look at the board, totally different than "normal" ones...

@PlasmaHH WTF is that ? Package-on-package technology from the 80's ?

@dim it is a prototyping unit. the mcu in question is available with 2k rom built in, but for development purposes you want to do it with an exeternal one

also its form 1979

Impressive. I can only imagine engineers from that time: "Dude, look at that new prototyping device from Zilog" - "Man, that's sick, let's fit in Unix in these 2k ROM!".

All you need is a piezo disc or ceramic on a board between your teeth and can get Hi Fi stereo sound, of course talking can be a problem.

@PlasmaHH We once used UV EPROMs as an image sensor for low Quality imaging raster scan with a lens

Ha Unix in 2K. Real coders only used Machine language.

@W5VO Sounds like the Keithley Parapalegic Analyzer

@PlasmaHH Sooner or later your going have a bunch of baby chips running around

@TonyEErocketscientist It got to the point where the HDD died, Keithley (then Tek) said we couldn't touch it because the drive was "special". The lab manager wanted to pull a Bob Pease with it. Now they have a Keysight unit.

I would have done the same AS Bob since I had 10 yrs experience testing HDD's

@laptop2d Not sure. One of these chips is clearly batting for both teams.

I swear... you want to help UK PCB manufactoring but they just screw up while a chinese firm just does it ...

"whaaa, China are taking manufacturing" ... well if you didn't make it easy for them maybe people wouldn't go to them
