Making input amplitude and
trigger settings becomes much
easier when the effect can be
observed immediately. Setting
values can be superimposed
on the wavefor m display to
maximize the waveform area,
or you can separate the display
areas to enhance the legibility
of setting items.
"Making settings is too complicated if I can't see the waveform!"
Make settings on screen while watching the waveform. No Problem!

High-speed 20 MS/s sampling provides ample margin
The operation principle is the same as for a digital oscilloscope: data are stored at
high speed in the high-capacity internal memory. Even with all channels operating
simultaneously, sampling rates up to 20 megasamples per second (50 ns cycle) are
possible. This ensures that sudden event spikes and instantaneous waveform changes
are captured reliably.
■ Semiconductor memory storage
Units using hard disks or other mechanical media for storage are vulnerable to
vibrations and therefore are not ideal for automotive measurement and similar
applications. By saving data in semiconductor based memory without any mechanical
drive parts, the Memory HiCorder is much more suited to such applications. Simply
back up the data later to CF card or USB memory, and you're done.
No Problem!
