I want to capture all the data from a single track of a DVD
During maintenance of equipment that uses magnetic
cards, I want to record all data read at once to make it
possible to identify errors
In response to these requests, the MEMORY HiCORDER 8855
supports large-capacity memory. The memory of the 8855 can be
expanded to up to 512 megawords (1 GB). Even at a samping
rate of 20MS/s, the 8855 can record for up to 12.8 seconds (2
channels, with a maximum of 256 megawords/channel)
This function allows you to divide a large
amount of free memory into small blocks
and save the waveforms from each trigger in
these blocks. Reducing the amount of dead
time durin g s eq ue nt ia l s av es mean s t ha t
continuously occurring triggers are not missed.
(Minimum setting of approximately 1 ms)
Sequential saves assures minimal dead time
With the 8855, measurement can be stored with
a resolution of 16 bits. This allows more precise
verification of signal waveforms. With its high
sampling speec of 1 MS/s, the 8855 can be used
for detailed signal analysis.
1 MS/s and 16-bit high resolution
FFT capabilities include single-signal FFT for
spectral analysis, two-signal FFT for transfer
function analysis, and octave analysis for
acoustic analysis. This is a very convenient
function because FFT analysis can be performed
for any portion of an extended waveform
captured by the memory recorder.

Perfect for inspecting storage media such as CDs, MOs, DVDs, and HDDs
- Application Examples -
When equipped with its maximum memory capacity, the 8855 is useful for
designing and analyzing digital A/V, communications, and information-related
equipment, and for inspecting production lines. By observing high-speed logic
signals and analog waveforms simultaneously, you can determine the control
sequence at a glance.
Analyzing operation of digital A/V equipment
Single-track data, such as that on hard disks, can
be batch recorded into the long
memory and then scanned for
corrupted bits.
When maintaining or inspecting equipment that uses
magnetic cards (such as the automated wickets at
railway stations), the data read can be batch recorded
and anomalies observed using the waveform search
or zoom functions.

Railway car defect analysis
All data for current waveforms of the main power motor
and correlating waveforms of relay signals can be
recorded on the 8855. Print the data using the optional
printer.
● Investigation of notch curves and cam synchronizer
waveforms
● Main circuit current waveform recording by clamp meter
● Waveform recording of cam contact signals by logic probe
● Waveform recording of cam contact signals using analog
input
● Investigation of electric brakes
● Waveform recording of MG starting current by clamp meter
I'd like to observe the control signal from a CPU,
signals from the various sensors, and the actual
movement all at the same time
I'd like to observe the load fluctuation waveforms
that result when power is turned on or off
simultaneously with the control logic signals
HIOKI has met these requests by providing the MEMORY
HiCORDER 8855 with isolated input for all channels, a
sampling rate of up to 20 MS/s, digital conversion with
a resolution of 12 bits, and the ability to measure up to 8
analog and 16 control logic channels simultaneously.
