1. Summary
DP6020 probe is the low voltage differential probe with float ground testing function. Test voltage
±20V(DC+Pk), maximum bandwidth up to 200MHz, with 10:1 attenuation setting, can largely decrease the
circuit load. With the overload alarm function, the DP6020 can adapt with any oscilloscope with 50Ω BNC
input, and can be powered by the USB port on oscilloscope or other computers. Widely used in many
applications, DP6020 can provide excellent general differential signal testing for high speed power
measurement, vehicle bus testing and digital system design.
2. Application
 Floating voltage measurement
 High speed power testing
 Digital differential bus
 Vehicle serial bus（CAN、LIN、FlexRay）

7. Operating Steps
 The range of the voltage under test should be estimated before the test. Voltage surpassing the
measuring range could possibly damage the probe and the product.
 Connect the input and output cable to the probe and connect the probe with oscilloscope or other test
devices.
 The green power indicator will be lighted when the power supply adaptor connects with the voltage
probe. When the voltage under test surpass the range, the indicator will be lighted along with the
buzzer.
 Set the attenuation ratio of the oscilloscope or other devices to 10:1, input impedance to 50Ω (If the
probe output port is connected with 50Ω thorough type load, the input impedance should be 1MΩ)
Adjust the sensitivity of the oscilloscope according to the voltage under test
 Connect the clips according to needs and start the test. The main body of the probe should be put
away from the high voltage pulse circuit to minimize the interference.
 Turn off the power of the circuit under test after the test is over, then turn off the power of the probe
and disconnect the two input ports from the point under test, and unplug the BNC connector from
oscilloscope.
