Capturing Screenshots (Bitmaps) from Rigol OscilloscopesWhen a USB flashdrive is inserted in the connector under the screen, our oscilloscopes can save screen images (bitmaps) as files on the flashdrive. We can then transfer those files to our computers and thereby obtain images of traces to place in writeups of experiments. |

1. Insert a USB flashdrive in the connector under the oscilloscope screen. 2. When you have a trace you wish to save, freeze the trace with the RUN/STOP button. |

10. When you have accumulated a group of screenshots, simply remove the USB drive from the oscilloscope and plug it into a USB port on the keyboard or the back of your computer. Open the drive icon by double-clicking on it, and drag the files of interest to a folder that you have previously established. (Name the folder with the lab date or title, and at the end of the day, make sure it is in the overall folder for your lab group. It is important that your files not be confused with ones obtained by the lab group that shares your setup on another day.) You may wish to select each file in turn and replace its automatic filename with a more descriptive filename. To return the USB drive to the oscilloscope, you must first dismiss it from the computer. If its window is open, click the eject symbol next to the drive's name. You can also highlight the drive on the desktop and select "Eject" from the File menu, or you can drag the drive's icon to the trash, which turns into an "eject" symbol. |
