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 TDS2004C
100 MHz
if you are checking a TDS1012C-EDU, TDS2012C, TDS2014C,
TDS2022C, or TDS2024C
