An unusual one. On all of the LS-120s that I've had, the manual ejection pinhole is in the middle of the eject button itself.

If it is an LS-120, then that oscilloscope might have the "Infinium performance upgrade kit", in which case it's actually DOS+Windows 98.

Are you going to do the safety check when December 2109 rolls around? (-:

It is not merely FD-R but actually FD-RW. (-:

Indeed, it might even be upgradeable to LS120.

So… the dead Philips scope is up today. Well it still works but I won‘t turn it on as the filter cap has burned out…

I was just looking at #oscilloscopes an see a non-linear relationship in $/MHz as frequencies increase.

#Rigol does well from $2/MHz @ 100 MHz to $7.50/MHz @ 2 GHz (vs. $20/MHz for a similar Tek scope).

Back in the days, #tektronix #oscilloscopes would come with a little roll of solder (3% silver as required by the ceramic terminal strips) inside the case for future repairs.
Maybe #sparc stations should have come with tubes of JB Weld… damn these things get brittle.

It’s #signalsaturday and I’m continuing the #CuteGen™️ test series by looking a bit at the harmonics 🙂 How clean is it?

Starting at 1kHz I’m using my #Siglent #oscilloscopes powerful FFT functionality and with harmonics >60dB down, this little thing really is a decent audio function generator.

I then moved to the spectrum analyzer and did some tests at (much) higher frequencies. Only included 10 and 30MHz here, but pattern is clear: harmonics are generally nicely attenuated, more than 60dB, although at the high end, it’s not quite that much, more like 50dB and a sub-carrier spur appeared as well. Makes me wonder how well the 60MHz version performs 🤔

I was given a load of old #Tektronix manuals that were going to be dumped. Some include software. Would anyone be interested in them before they go on eBay? They're in very, very good condition.

EDIT: These are located in Galway, Ireland. I'm happy to post to US but at minimum that will cost €173.
