Oscilloscope Question

argonrepublic · 26th January 2006, 01:11 AM

I have an extra Oscilloscope. A friend wants to buy it and asked me it's bandwidth.
I don't know the answer. I have used it to follow audio signals and more recently I checked an Oscillator IC with it.
Sweep time range from .5 sec. to .2 uS. What is the bandwidth

Hi argonrepublic,
It sounds like a decent 'scope. I think you mentioned the model numbers somewhere.

The best way is to "google it" and read off the manufacturers specs. It could be in the range of 50~100 MHz. Remember, you want the vertical amplifiers specs. The timebase is high enough to warrant a higher vertical bandwidth.

What does he want to do with it?

The voltage setting is 5mV-20V. I am not sure what he wants to do with it. Hopefully buy it! Maybe I should try to trade here for some PCBs.

Hi argonrepublic,
What is the make and model again? How old do you think it is?

You should be able to trade for something decent. It sounds like a really good service scope.

I have a military surplus HP scope that is supposed to be a 60 MHz BW unit and the minimum sweep time is 0.1 uS per division.

It sounds like your scope may be in the 30-50 MHz BW range.

The Oscilloscope is a KBElectronics 33330 Dual Trace. Aboout ten years old. I can't find info online. Only a few for sale @$40 which doesn't seem like a legitimate price because I started 8 of them on ebay at $40 and got $80-$100each. I am not not trying to jack up the price here. Just stating that there is some demand for this model so it must be OK.
