ch 32 logic channels
High-speed
Isolated testing
The Memory HiCorder MR8827 achieves isolated input between the main unit
and channel or between channels, at a maximum sampling speed of 20 MS/s
on all channels.
It provides mixed recording that combines 32 analog channels and 32 logic
channels, and logic input can be expanded up to 64 channels.
Welcome to the next generation of Hioki Memory HiCorders that deliver multichannel waveform recording of a diverse array of signals to meet complex and
demanding applications.
* When using 64 logic channels, 28 analog channels are available.

The high-performance 8826 delivered the most analog channels out of all portable-type
Memory HiCorders. The new MEMORY HiCORDER MR8827 inherits that concept and evolves
even further.

Standalone testing
Output recorded waveforms
without modification
For example, you could output actual waveforms recorded
from a car without modification, and then use them for
standalone testing. You can also generate isolated output
of up to 15 V without a generator or amplifier, which is
traditionally necessary in order to generate output while
varying the signal's amplitude and frequency.
