Why do you need Deep
Memory and a High
Sampling Rate?
To see more time
When you are able to store more
samples that you have obtained in
the memory, you can view the signal
at a longer time. This will be the best
way to understand the use of deep
memory.
Ease of use
The U2701A and U2702A USB modular oscilloscopes are equipped with Hi-
Speed USB 2.0 interface for easy setup and plug-and-play. Hence, this ease-of
use makes the oscilloscopes ideal for the education, design validation, and
manufacturing environment.
A longer capture time gives you a
better visibility into cause-effect
relationships in your designs, which
significantly simplify your root-cause
debugging. It also allows you to
capture start-up events in a single
acquisition.
The need to stitch together multiple
acquisitions or set precise triggering
conditions are no longer necessary.
You can spend less time finding
events, and more time analyzing
them.
To see even more details
The relationship between memory
depth and acquisition rate is not as
obvious. All scopes have a “banner”
maximum sample rate specification,
but many can only sustain these rates
at a few time base settings.
Figure 1. The dual-play capability allows U2701A and U2702A USB modular oscilloscopes to be
used as standalone units or fitted into a cardcage.
Higher sampling rate
By offering sampling rate more than
twice the acquired signal bandwidth,
aliasing can be prevented. With
more sampling data captured, higher
accuracy of your test and analysis
results can be achieved.
