content: Hellowhat would be the best oscilloscope for me to recommend for my company? Im working as a service tech so we need a oscilloscope that is good for troubleshooting. I dont know what the budget is but probably around 2000 eur.

content: 1. Make a list of what you need\want2. Look for scopes that offer what you these points3. Check your budget. If needed go back to 14. Call some companies, let them show what they got. They will probably help you out and lend you a scope for some weeks to play with.5. Buy the one that fits you best.

content: Quote from: McBryce on April 30, 2015, 12:05:10 pmAbsolutely right. For servicing big, high voltage equipment in fixed locations at customer sites away from a workbench, a handheld unit like a Fluke scopemeter might be the right thing. There are other types of servicing that might be best done with a bench scope. Bandwidth requirements for servicing could vary all over the map, again depending on the device.

content: Hello and thanks for all the replaysi should have been alot more specific in my earlier post sorry..1: We manufacture and service multifunction calibrators, so need a scope for electronics troubleshooting. Maximum +-20 volts and 250mA measurements.2: Bandwidth requirements minimum 100mhz3: Budget max 2.000 euro.4: Will just be moved occasionally around the service department. So no need for a handheld scope.5: Integrated logic timing analyzer would be a big plus.-Mao.

content: Quote from: ThunderMink on May 04, 2015, 10:13:38 amEasily doable within budget, but... Oscilloscopes usually do not include current measurement functionality with the supplied probes.Current could be measured over a shunt (note that, if you do high-side monitoring and also are using a second probe to do ground-referenced measurements, you may need a differential probe), or using a sensitive current clamp with sufficient bandwidth for your purposes. Do you already have the necessary current probes? If not, check if there's a budget for that.QuoteHow many analog channels? Is 2 enough, or do you need 4? That has a noticeable impact on the price.QuoteHow many channels you need to monitor simultaneously, and how fast will it have to sample?

content: I'd look at a Keysight 2000 series (the MSOX2012A could be a good fit and within budget). Stretching the budget to be able to afford a 4 channel oscilloscope would be a wise thing to do. I never want to go back to a 2 chanel oscilloscope.
