Test Trigger Sensitivity
Steps:
::
: 1、Press the button “DEFAULT/SETUP”, and set the VOLT/DIV to 500mv/div, set
SEC/DIV to 25ns/div.
2、Connect the oscilloscope channel 1 to the standard sinewave generator
3、Set the standard sinewave generator frequency to 10 MHz
3、Set the generator output level so the Vpp measurement is about 500 mV.
4、Press the button “set to 50%”. Adjust LEVEL as necessary and then check that
triggering is stable.
5、Set the generator frequency to:
25MHz if you are testing a SDS1022D
40MHz if you are testing a SDS1042D
60MHz if you are testing a SDS1062D
100MHz if you are testing a SDS1102D
150MHz if you are testing a SDS1152D
200MHz if you are testing a SDS1202D
6、Set the generator output level so the Vpp measurement is about 750 mV.
7、Press the button “set to 50%”. Adjust LEVEL as necessary and then check that
triggering is stable.
8、Test channel 2 with the same method
Test Noise
Steps: 1、 Set the both channels VOLT/DIV to 2mV/div,SEC/DIV to 2.5µS/div
2、 Set two measure parameters as “CH1,Vpp” and “CH2, Vpp”
3、 Check the Vpp measurement is ≤1.2mV (other VOLT/DIV is 0.6 DIV )
4、 Change the VOLT/DIV, and check the Vpp until all the VOLT/DIV of both channel
have been tested.
