Performance verification Test EN 4 Performance verification Test This chapter takes the DPO7504E machine as an example to introduce the performance verification and testing methods and processes of the DPO7000 series digital oscilloscope. The testing equipment used in this manual is FLUKE5000. Note: 1. Before performing performance verification tests, please ensure that the oscilloscope passes self check and self calibration. 2. Before performing each performance verification test below, please ensure that the oscilloscope has been preheated for at least 30 minutes. 3. Before or at the end of each performance verification test below, please set the oscilloscope to the default settings.
4.1 Impedance Test 4.1.1 Index 4.1.2 Test Connection Diagram 4.1.3 Test Procedure 1. Connect the active signal probe of Fluke5000 to the CH1 channel of the oscilloscope, as shown in the above figure. 2. Configure oscilloscope: ⚫ Click on [CH1] in the button area to open the CH1 channel. ⚫ Set the vertical gear of CH1 to 100 mV/div. 3. Open Fluke5000, set its impedance to 1 M Ω, select the resistance measurement function, read and record the measured resistance value.
