2. Connect the oscilloscope channel under test to the leveled sine wave generator
as shown in the following figure:
3. Set the oscilloscope Vertical Scale (volts/division) to 500 mV/div.
4. Set the oscilloscope Horizontal Scale (seconds/division) to 10 ms/div.
5. Set the leveled sine wave generator frequency to 50 kHz.
6. Set the leveled sine wave generator output level so the peak-to-peak
measurement is between 2.98 V and 3.02 V.
7. Set the leveled sine wave generator frequency to:
40 MHz if you are checking a TDS1001C-EDU
50 MHz if you are checking a TDS2001C
60 MHz if you are checking a TDS1002C-EDU
70 MHz if you are checking a TDS2002C or TDS2004B
100 MHz if you are checking a TDS1012C-EDU, TDS2012C, or
TDS2014C
200 MHz if you are checking a TDS2022C or TDS2024C
8. Set the oscilloscope Horizontal Scale (seconds/division) to 10 ns/div.
9. Check that the peak-to-peak measurement is ≥ 2.12 V.
