This is impossible when you don't tell in which country you live.Sobakava said:Could you post pricing information if do you have. I mean not official prices.
Real prices :wink:
I don't have it, I just read it at the library. Try to see if your library has it or order it from Elektor. Or maybe another member can scan the article?bomba said:Me!!!!
Could you post the elektor article.
Thanks you

nicleo said:Any comment on Lecroy WaveMaster 8000A Series? I saw an engineer from Lecroy demontrated the scope in our lab before. It looked good and cool. Like a PC.
I own a 3054 either. I found its limitation when I set 24V voltage offset, meanwhile I intended to zoom in voltage ripple in order to find out its detail state. That is to say if you have a relative large DC offset, you can't magnify its AC detail in large display scale. Can anyone could suggest other substitute oscilloscope?flatulent said:The Tektronix scopes you list have a residual noise problem that is in the digital section. It will be half a major division at the low signal levels and is reduced to one pixel at the high signal levels. Tektronix knows about this but will not change it as long as the scopes sell. Otherwise I like the 3054 very much and would not exchange it for some other brand.
The @gilent scopes do not have this noise problems. They have fewer features and are slightly less intuitive to operate.
A google search will give you discount dealers. The discount is usually about 10%.
Because I can't determine the ripple bandwidth. If you push AC coupling button, that means you possibly filtered out some ingredient that might reside in ripple.echo47 said:bittware - why not simply press the AC Coupling button?
I agree.alex840 said:from my point of view (mainly analog engineering):
1. it is very useful to have 4 channels.
2. Tek - piece of junk. yeah, ok, it's a good scope to observe what's happening with your clock signal over time, but 15bytes(or even less) of memory without possibility to extend it... For this money(TDS2024) you can buy only some korean scopes. TDS3000 - very strange series. Good set of features and, again, limited memory. Price is less than others with the same bandwidth, but only due to limited memory, i think. Good scopes (i mean good usability) for a simple work. unusable to find one glitch over 10ms if you don't know how the glitch looks like.
3. HP/@gilent - good. Long memory, good syncro, very useful. 54645 - you will be able to work with full speed at 5ms/div. Maybe math is limited and zoom is not comfortable - you can't see original and zoomed signal simultaneously.
4. LeCroy - I don't know why but I like these scopes. ;-) I started with 9304A, then LC334A(you can see 8 traces!), LT224, LT374... The last I've seen - 6050. this one is the best. Excellent big screen, good syncro, long memory, 8 traces on the screen, very useful math.... Disadvantages - it will take time until you get used to it. Old models have quite short memories. New ones - look more like PC than as an osci - w2k, desktop, antiviruses...
