I Met My Old Buddy

(1/2) > >>

Mechatrommer:
today my colleague asked me to show her how to setup an oscilloscope in my school. so this guy has to show up, so here it is, think i will not see "him" very frequently from time to time now, so take this chance and let me introduce you... my old buddy... before my rigol. while setting it up, i still cannot get it right, esp the reading (horizontal and vertical). still confusing as hell even after 1++ year happy with rigol. if you have seen this species, pls leave your comment.

dimlow:
Hey, there is more than one button on the rigol you know ;D

Nice old design [ but relatively new make of GW?] analog scope.  I had a similar looking one back in the 1980s!!  By Trio-Kenwood.  5 MHz, I worked it to death; it died 2 years ago and I wonder whether I should repair it or trash it; I went looking for a scope, found Dave's review, found Rigol, and the rest is history.

this chap got extra. vert var and swp var. the most bugging mystery for me until now. after having rigol, i started to learn what is ac/dc/gnd/int/ext pretty much everything i learnt backward ;D CAL is not operational anymore, dont know if its broken or is just me dont know how to use it, it just a single metal, no ground like rigol has. even the trigger (pull slope?) is delusive back during the old day. i only can confirm/understand two button very well, ie volt/div and time/div. but with previous mentioned knobs/buttons, i pretty much like tried to tinker everything without having a clue to get the phosphor moving in the scope monitor.

this is 20MHz scope IIRC from the manual. last time i searched the closest brand is GW Instek. but operating it, make me highly doubtfull. i think this is GW'nese no brand name cro. this thing is still working as can be seen in the picture, but bid farewell to this buddy.

dimlow:
Im guessing pull slope is for falling edge trigger. The vars, i have no idea. I never had an analogue scope!!! well I did when I was about 11, but back then I didnt know what it was for. All the other controls I would have thought are pretty basic.
