TDS 510A Performance Verification and Specifications

Nominal Traits
This section contains tables that list the electrical and mechanical nominal traits
that describe the TDS 510A Digitizing Oscilloscope.
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 that can be resolved by the 8-bit A-D Converter, 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/divi-
sion setting.
2
GND input coupling disconnects the input connector from the attenuator and connects a ground reference to the input of
the attenuator.

The sensitivity ranges from 1 mV/div to 10 V/div in a 1–2–5 sequence of coarse settings. Between a pair of adjacent
coarse settings, the sensitivity can be finely adjusted. The resolution of such a fine adjustment is 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.
