TDS 500D, TDS 600B & TDS 700D Performance Verification and Specifications

Nominal Traits
This section contains a collection of tables that list the various nominal traits
that describe the TDS 500D, TDS 600B, and TDS 700D oscilloscopes. Electrical
and mechanical traits are included.
Nominal traits are described using simple statements of fact such as “Four, all
identical” for the trait “Input Channels, Number of,” rather than in terms of
limits that are performance requirements.

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 of the oscilloscope input that can be resolved by the 8-bit A-D Converter. Expressed
as a voltage, a DL is equal to 1/25 of a division times the volts/division setting.

The sensitivity ranges from 1 mV/div to 10 V/div (for 1 MW) or to 1 V/div (for 50 W) in a 1–2–5 sequence of coarse settings
with Fit-to-Screen off. Between coarse settings, the sensitivity can be finely adjusted with a resolution equal to 1% of the
more sensitive coarse setting. For example, between 50 mV/div and 100 mV/div, the volts/division can be set with 0.5 mV
resolution.
