Good job buchler joe! It seems to be the one. One question... is 5mhz good enough for audio use? It is very cheap indeed and if it fits in the rack I am very tempted here... ----- Original Message -----

I also own a 15mhz NS 215 miniscope. As a general rule, figure you need 10x bandwidth to effectively use a scope. You can get by with 5x bandwidth. I find this to be true regularly. Recently I was working on a project with a 15mhz to 20mhz oscillator and found although my scope was adequate, it was definitely pushing it as the trace was not as clean and precise as I like. The signal was not even readable on my 15mhz scope. So, a 5mhz scope, in practice, is VERY usable up to about 500khz, and usable up to about 1mhz. Considering, that in most cases, you are working with signals below about 30khz, 5mhz should be adequate. Looking at the pdf, it has a knob for trigger, so, I assume that it IS a triggered sweep scope, which is good. I think if you want something that will have a chance at fitting in your rack, this is probably the only choice. My only caveat would be that if you think you may want to build modules, or use a scope for other reasons, this is a fairly limiting model. But, as a module to make it easy to see what's happening, it will work just fine. Daryl

Hi Andreas > About what is good enough I am asking you guys that has oscilloscopes. I > have no clue, but I want one that shows my sounds decently and doesn't loose > it if it goes up the scale and such. You have to differ betwee the maximum frequency-range and the secure triggering circuit. This simple Conrad oscilloscope is really good enough in respect to the frequency range, but I cannot judge, whether the triggering facilities of htis scope are good enough. E.g if you want to display the sound behind a modulated low pass filter that gets very "dark" from time to time, the trigger might get lost. In this case you need a separate input to trigger with the input signal of the VCF. If it is no trouble for you to readjust the trigger circuit for this sound, then a simple scope like the Conrad model should be good enough for you. On the other hand I would prefer a two channel scope to compare what happenes before and after a module. So, I fear, I can't give you a clear answer.
