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.

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.
