This subsection contains a collection of tables that list the various nominal
traits that describe the TAS 465 Analog Oscilloscope. Included are electrical
and mechanical traits.
Nominal traits are described using simple statements of fact such as Two,
both identical" for the trait Number of Input Channels," rather than in terms
of limits that are performance requirements.
! "
Number of Input Channels Two, both identical, called CH 1 and CH 2.
Input Coupling DC, AC, or GND.
GND input coupling disconnects the input connector from the attenĆ
uator and connects a ground reference to the input of the attenuaĆ
tor.
Sensitivity Range 2 mV/div to 5 V/div.
The sensitivity ranges from 2 mV/div to 5 V/div in a 1-2-5 seĆ
quence.
Trace Separation Control Range w ±4 divisions.
Bandwidth Selections 20 MHz and FULL, selected independently for each channel.
TAS 465 Rise Time v 3.5 ns.
Nominal rise times are calculated from the following formula:
Rise Ą Time Ą ( ns ) +
350
BW Ą ( MHz )
Vertical Position Range w ±10 divisions from graticule center.
TekProbe Interface Detects 1X, 10X, and 100X attenuator probes.
