Understanding Oscilloscope Functions

TDS1000/2000-Series Digital Oscilloscope User Manual

The next table lists the time bases that you should use to avoid

aliasing at various frequencies and the respective sample rate. At the

fastest SEC/DIV setting, aliasing is not likely to occur due to the

bandwidth limitations of the oscilloscope input amplifiers.
