Hi, I have a DS1102E (that I have hardly used) and a DAC to test, the DAC should be outputting a voltage in 0.25v increments every 2 seconds, how do I see and properly verify this on a scope like mine? I have no idea how to use it, please be gentle. Can someone point me in the direction of some basic instructions on how to verify the DAC works? Thanks. Richard |

If you wanted to see 5V total then you would need 20 steps at 2 seconds each. This is probably better done with a DMM. Easiest to do with a V-O-M if you don't care about exact values. Just watch the needle move... Anyway, you want 40 seconds spread across 12 divisions so you want something over 3 seconds/division. You're in luck, the scope has 5 seconds per division. Now all you have to do is set the trigger at the first step above 0V (using Trigger Level knob) and move the trigger point all the way (or even just part way) to the left (using Horizontal Position knob) of the display. |

My suggestion would be start by reading the manual, then watch some videos on YouTube on how to use an oscilloscope. Once you know how to use the scope, you won't have to ask how to perform each individual task you come across. Spend some time playing around with it, you'll get the hang of how it works fairly quickly. Be sure to watch Dave's video on how to not blow up your oscilloscope too. |

Any subject you want. Warning you can get addicted. Really |

There's a great video series in the 'stickies' at the top of this forum. https://www.eevblog.com/forum/beginners/oscilloscope-training-class-(long)/ Most scopes provide a probe compensation signal on the front panel. This can be viewed and used as something of a training signal. Try different triggers, different volts/div, different time/div and, for DSOs, moving the trigger point left and right on the screen. Could even try FFT... |
