The 3000T X-Series has excellent signal integrity, including full
bandwidth to 1 mV/div and the ability to get up to 12-bits of
resolution using the high resolution acquisition mode�
Some oscilloscopes in this class limit their bandwidth at smaller
volt-per-division settings without on-display user notifications�
This is likely to keep the noise acceptable at lower volt-per-
division settings�
Table 2 shows a comparison of the typical noise floor at 20 μ/div
between the normal and high resolution mode� You will notice
that the noise floor performance improves as much as five times�
Figure 12� High resolution mode allows you to lower your noise and
increase your resolution up to 12-bits�
