≥5 Years
1
The time that reference waveforms, stored setups, and calibration constants are retained when there is no power to the
oscilloscope.
2
Data is maintained by a lithium poly-carbon monofluoride battery.
Nominal Traits
Nominal traits are described using simple statements of fact such as “Two,
identical” for the trait “Input Channels, Number of,” rather than in terms of
limits that are performance requirements.

1
Displayed vertically with 25 digitization levels (DLs) per division and 10.24 divisions dynamic range with zoom off. A DL
is the smallest voltage level change that the 8-bit A-D Converter can resolve, with the input scaled to the volts/division
setting of the channel used. Expressed as a voltage, a DL is equal to 1/25 of a division times the volts/division setting.
2
The sensitivity ranges from 2 mV/div to 10 V/div in a 1–2–5 sequence of coarse settings. Between consecutive coarse
settings, the sensitivity can be finely adjusted with a resolution of 1% of the more sensitive setting. For example, between
50 mV/div and 100 mV/div, the volts/division can be set with 0.5 mV resolution.
