Characteristics Tables
This section lists the specifications for the DSO module. All specifications are
guaranteed unless noted “typical.” Specifications that are marked with the
n
symbol are checked in the Performance Verification chapter of this manual.
The performance limits in this specification are valid with these conditions:
H
The DSO module must have successfully passed self calibration at an
ambient temperature b20
_
C and +30
_
C and after a warm-up period
of 30 or more minutes at these conditions.
H
The DSO module must be in an environment with temperature, altitude,
humidity, and vibration within the operating limits described in these
specifications. This includes the warm-up period of 30 or more minutes at
these conditions.

Net offset is the nominal voltage level at the DSO module input that corresponds to the center of the A/D Converter
dynamic range. Offset accuracy is the accuracy of this voltage level.
