3) Connect the function generator output to the CH1 input.
Acquire data with the slope in RISE and the trigger level at 300 mV, read the trigger
point data ten times using the cursor, and check that the average value is within the
following range: 170 mV ≤ Cursor1 ≤ 430 mV
Similarly, each average value of ten trigger point data should be within the following
corresponding range:
Slope Trigger level Permissible range
300 mV 170 mV ≤ Cursor1 ≤ 430 mV
300 mV 170 mV ≤ Cursor1 ≤ 430 mV
0 mV –100 mV ≤ Cursor1 ≤ 100 mV
0 mV –100 mV ≤ Cursor1 ≤ 100 mV
–300 mV –430 mV ≤ Cursor1 ≤ –170 mV
–300 mV –430 mV ≤ Cursor1 ≤ –170 mV
4) Test all channels in the same manner.
