It was great that Galaxyrise posted that info: I was sure that function existed on the DS2000 when you first posted the question, but I couldn't find it in any of the menus or docs I looked in - so then I thought I must have confused it with another DSO (since I owned 3 other ones in a span of about 2 months). |

Hello, can someone explain me how to use the self cal feature? The manual says i should connect the trigger out on the back with CH1, CH2 and Extern trigger. Does that mean, i have to connect all at once? What is the best way to connect one BNC to all 3 inputs? Do i have to calibrate or is it calibrated on delivery? |

ANSWER: The DS2000 series self calibration routine specifies no connections to the inputs on the front panel. Early versions of the User's Manual are incorrect. --- End quote --- But I did not find new versions of UM, where this is has corrected :) I saw special cables and simpe board for DS4000 calibration, and for DS6000 is document: http://www.tequipment.net/assets/1/26/Documents/Rigol/DS6102/ds6102_doc_7.pdf |

What is the best way to connect one BNC to all 3 inputs? --- End quote --- That's a mistake copied from the DS4000 manual - you should have no connections to front BNCs when you do a self-calibration. --- Quote ---Do i have to calibrate or is it calibrated on delivery? --- End quote --- It's been factory calibrated - but it's not a bad idea to do a self-calibration occasionally to optimize the signal path for maximum measurement accuracy. You can run the routine at any time but should always run it if the ambient temperature changes by 5°C or more. Just make sure it has been powered on for at least 30 minutes before running the self-cal. |

DS2000 User's Guide 2012-09-21 http://www.rigol.com/download/Oversea/DS/User_guide/DS2000_UserGuide_EN.pdf DS2000A User's Guide 2013-12-02 (same as DS2000 + 50 ohm input option) http://www.rigol.com/download/Oversea/DS/User_guide/DS2000A_UserGuide_EN.pdf Page 14: --- Quote ---Self-calibration The self-calibration program can quickly make the oscilloscope reach the best working state to get the most precise measurement values. You can perform self-calibration at any time especially when the change of the environment temperature is up to or more than 5 ?. Make sure that the oscilloscope has been warmed up or operated for more than 30 minutes before the self-calibration. Disconnect all the input channel connections, and then press Utility -> Self-Cal and the self-calibration interface as shown in the figure below is displayed. Press Start and the oscilloscope will start to execute the self-calibration program. Press Exit to give up the self-calibration operation at any time and return to the previous menu. Note: Most of the keys are disabled during the self-calibration. --- End quote --- |
