Nominal Traits
This subsection contains a collection of tables that list the various nominal
traits that describe the TAS 475 and TAS 485 Analog Oscilloscopes.
Included
are electrical and mechanical traits.
Nominal traits are described using simple statements of fact such as "Four,
all identical"
for the trait "Number of Input Channels," rather than in terms of
limits that are performance requirements.

Description
Four, all identical, called CH 1, CH 2, CH 3, and CH 4.
DC, AC, or GND.
GND input
coupling disconnects the input connector from the atten-
uator and connects a ground reference to the input of the attenua-
tor.
2 mV/div to 5 V/div.
The sensitivity ranges from
2 mV/div to 5 V/div in a 1-2-5 se-
quence.
~ ±4 divisions.
20 MHz and FULL, selected independently for each channel.
:s; 3.5 ns.
Nominal rise times are calculated from the following formula:
