Common Mode Rejection Ratio
(CMRR)
100:1 at 60 Hz, reducing to 20:1 at 50 MHz, with equal Volts/Div and
Coupling settings on each channel.
1Net Offset = Offset - (Position × Volts/Div). Net Offset is the voltage level at the center of the AD converter dynamic range. Offset
Accuracy is the accuracy of this voltage level.
2The samples must be acquired under the same setup and ambient conditions.
3The values given are the maximum absolute difference between the value at the end of a specified time interval after the midlevel
crossing of the step, and the value one second after the midlevel crossing of the step, expressed as a percentage of the step
amplitude.
4Reference is a 9div pp sine wave input sampled at 200 MS/s for the TDS 310, 500 MS/s for the TDS 320, and 1 GS/s for the
TDS 350.
