CH 4 (TDS 420 and TDS 460) when both channels have equal volts/
division and coupling settings
≤

vision and coupling settings (TDS 420 and TDS 460).

Net Offset = Offset – (Position x Volts/Div). Net Offset is the voltage level at the center of the A-D converter’s dynamic range.
Offset Accuracy is the accuracy of this voltage level.
4
Position Accuracy is confirmed in the Performance Verification Procedure (Section 4) by passing the checks for Offset Accuracy
and DC Voltage Measurement Accuracy (Averaged).

The limits given are for the ambient temperature range of 0 C to +30 C. Reduce the upper bandwidth frequencies by 2.5 MHz for
each C above +30 C.
