Here's a question for those who are smarter than I (so, all of you... :D )
What are the easiest ways to measure scope probe bandwidth and frequency response?
For bandwidth, can I just use a BNC to probe tip adapter and plug into my Leo Bodnar Pulser?
And for frequency response I'll have to buy a spectrum analyzer to do frequency sweeps or is there some way I can use FFT on my scope and get meaningful results?
tggzzz:

Plus Floppies are more convenient to carry your files with you and then go to computer, or some body else's in another office, and load your files there. Portability.

Floppies are an electromechanical part that is unreliable.

My Apple Smalltalk floppies from the 1980s still work.
I'm not sure that flash drives won't leak electrons over that time interval. ISTR I've seen statements of "years" rather than "decades", which is enough for me to want to keep multiple copies of backups.

This one will be longer than the previous and again....the location be known only to me. ;) I probably won't be back on the blog until at least Saturday or Sunday. So obviously that will put me at least 10 pages or possibly more behind. Now I could follow the blog on my phone but I have no intention of doing so. If you are gonna get away....then get away. ;D So if there is something specific for me it will have to wait until I return or send me a PM.
Does this trip involve a female? No comment. Decadent activities? No comment. Illegal activities? Why yes, at one time one was but no longer. No further clues. >:D
I just know you all be jealous. :P :P :-DD

Commodore update time. Did a display transplant from my SR4912 calc into the F4902 and everything works just fine. Messaged the seller regarding the display and I got £5 refund, so that will be useful towards payment for another donor Commodore calculator of which there are many scientific and other special function calculators out in the wild that could donate a 12 digit display to return the SR4912 back to full health again.
There is nothing quite like the nice cosy, warm display of a nice ruby red LED display. :-+

But yeah if the computer is close to the scope it's OK to transfer via a cable be it GPIB or serial.
Don't know if the old HP MSO can transfer screen capture files via RS232, will need to have a look in the manual. That would be cool if it could.

Of course it can. I use the HPAK Bench Link software
https://www.keysight.com/gb/en/lib/software-detail/computer-software/download-benchlink-xl-54600-software-version-2-1000000922epsgsud.html
https://www.keysight.com/gb/en/assets/9018-06303/quick-start-guides/9018-06303.pdf
It transfers data as well as images.
There are other options see
