Characteristic
Description
This is the upper frequency for Analog Bandwidth when the instrument has 20 MHz bandwidth limiting
turned on.
20 MHz
Upper-Frequency Limit,
20 MHz Bandwidth
Limited, typical
Bandwidth of all trigger paths are similarly limited, except the External Trigger, which is not affected
by BW Limit function. Each channel is separately limited, allowing different bandwidths on different
channels of the same instrument.
This is the lower frequency for Analog Bandwidth when the instrument is AC-coupled
Lower- Frequency Limit,
AC Coupled
≤ 10 Hz.
<1 Hz when 10X, passive probes are used.

Rise Time, typical
Rise time is generally calculated from the following formula: Rise time in ns = 350 / Bandwidth in MHz
This is the capability of the instrument to capture single event pulses using the Peak Detect Acquisition
Mode.
The minimum single pulse widths for guaranteed 50% or greater amplitude capture are as follows:

This is the accuracy of the nominal voltage level represented by the code at the vendor of the A-D
converter’s dynamic range.
