Important safety information Important safety information This manual contains information and warnings that must be followed by the user for safe operation and to keep the product in a safe condition. To safely perform service on this product, see the Service safety summary that follows the General safety summary. General safety summary Use the product only as specified. Review the following safety precautions to avoid injury and prevent damage to this product or any products connected to it.
Important safety information or current rating of the lowest rated individual component of a product, probe, or accessory. Use caution when using 1:1 test leads because the probe tip voltage is directly transmitted to the product. Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal. Do not float the common terminal above the rated voltage for that terminal.
Important safety information Beware of high voltages Understand the voltage ratings for the probe you are using and do not exceed those ratings. Two ratings are important to know and understand: • • The maximum measurement voltage from the probe tip to the probe reference lead The maximum floating voltage from the probe reference lead to earth ground These two voltage ratings depend on the probe and your application. Refer to the Specifications section of the manual for more information.
Important safety information CAUTION: Caution statements identify conditions or practices that could result in damage to this product or other property. Terms on the product These terms may appear on the product: • • • DANGER indicates an injury hazard immediately accessible as you read the marking. WARNING indicates an injury hazard not immediately accessible as you read the marking. CAUTION indicates a hazard to property including the product.

Rotate the Trigger Level knob to adjust the trigger level as necessary and then check that triggering is stable. 16. Disconnect the test setup. 17. Repeat steps 1 on page 18 through 16 on page 19 for all input channels. Check Aux In edge trigger sensitivity This test checks the edge trigger sensitivity for the Aux In. 1.
Performance verification 6. 7. Set the sine wave generator output level to approximately 300 mV p-p into the power splitter. This is about 200 mV p-p on channel 1 of the oscilloscope. The AUX IN input will also be receiving approximately 200 mV p-p . Small deviations from the nominal 200 mVp-p oscilloscope display are acceptable.
Performance verification 2. 3. 4. 5. 6. 7. 8. Make a spreadsheet approximately as shown in the example in Appendix A. You only need to enter the values for column A and the equations. The values in columns B, C, D, E, F, and G are examples of the measured or calculated values. The PDF version of the technical reference manual (which you can download from www.tektronix.com/manuals), includes an empty spreadsheet for your convenience.
Performance verification Data verification To verify data, set the spreadsheet to present a line graph of columns D, E, and F. Verify that no error values (the blue line in the center) go above the yellow line (upper line), or below the purple line (lower line). For calculations involved in this example, refer to the data in the previous table (see step 1).
