The attenuators used are based on the expected value or range specified. Table 3-1 shows the attenuators used as a function of the expected value and range.

Using the Single-Ended Input 1V Range

When taking readings of low-level signals on the single-ended input, selecting the 1V range ensures the most accurate readings. This is achieved through a path directly to the A/D, which bypasses the attenuators and amplifier which can add noise and distortion to the signal (Figure 3-3).

The single-ended input 1V range can be set by specifying an

<expected value > of 1V in the MEASure or CONFigure command, or by specifying a range of 1V in the SENSe:VOLTage command:
