What
Users
Want
Start measuring without
delay
"Changing paper is a hassle, and printing speed should be faster!"
No Problem!
One-touch design takes the hassle out of the process. 50mm/sec print speed
No more need for cumbersome and time-consuming steps such
as threading the paper between rubber rollers and the thermal
print head. Simply drop the paper roll in place, pull the tip out
slightly, and close the door. As easy as one, two, three.
"I need measurement results in hand right away!"
No Problem!
50 mm/s printing speed produces results in a flash
Printing is twice as fast compared to the performance of
previous HIOKI products. No more waiting when printing out
data on site to show the client.
■ Hard copy of the display screen, then and there
Observed waveforms, setup parameters,
processing values, AB cursor readouts
and more--a simple push of a button and
the high-speed thermal printer gives
you a hard copy of the entire screen
contents. Saving as a BMP file on a CF
card or USB memory is also possible.
■ Print a complete A4 format report on site
If the customer requires a report, the 8847 can deliver
without delay. The A4 format printout shows waveforms
with high resolution. Even minute details and changes
can be detected easily, and measurement parameters used
for obtaining the data are also printed. Even in the age of
electronic communication, being able to produce a paper
document on the spot can be very effective and result in
enhanced credibility.

What
Users
Want
Monitor high-speed
signals
"1 MS/s is too slow for observing fast pulse edges"
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 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 a CF card or USB memory stick, and you're done.

"Making settings is too complicated if I can't see the waveform!"
No Problem!
Make settings on screen while watching the waveform.
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

What
Users
Want
Having an X-Y recorder
would be handy!
"An X-Y recorder uses paper, but electronic data would be better!"
No Problem!
X-Y recorder with electronic recording
Chart-type X-Y recorders are disappearing from
the market, but they had certain advantages that
are sometimes desirable. The 8847 brings them
back with features such as independent pen up/
down control. Because data are stored as a timebased series, electronic storage can be applied
to tasks for which paper archives used to be
necessary.
■ Pen up/down control
Individual pen up/down control is
possible during X-Y recording, not
only by using the Function buttons
but also via external signals at the
EXT. IN 1
EXT. IN 2
EXT. IN 3
EXT. IN1, 2, 3 connectors.
"There are scores of relays, and I need to measure the timing of them all!"
No Problem!
Max. 64 channels Logic input + 10 channels Analog input
The 8847 comes standard with 16 logic input
channels. Three more logic input modules with up
to 48 logic channels can be installed in place of
analog input modules, resulting in simultaneous
recording capacity for up to 64 channels in
total. All channels can be displayed on a single
screen, which is ideal for timing measurements.
Furthermore, simultaneous recording of analog
waveforms is possible in up to 10 channels.

What
Users
Want
Analyze data on a
computer
"I want to use a USB memory stick!"
No Problem!
Two types of USB 2.0 ports
Measurement data can be saved manually on any generic USB
memory device.
LAN terminal
USB receptacle A
USB receptacle B
* Automatic data saving as on CF card is not possible.
The USB interface conforms to version 2.0 specifications. Mass
storage devices can be used in the A type connector.
* Due to compatibility reasons, some USB memory devices may not work.
The B type connector can be used to connect the 8847 to a
computer for remote operation. If no USB memory stick is
available, internal data of the 8847 can be sent to the computer
via this USB connection for storage.
"I want to use a hard disk!"
No Problem!
Optional internal HDD
Measurement data can be saved automatically on the optional
80GB hard disk. The HDD is a factory option which will be
installed internally.
A slot for CompactFlash cards is also provided.
Data can be saved automatically on cards available from HIOKI.
* Automatic data saving occurs in close to real time and is possible while saving
data in the internal memory (128MB) of the HiCorder. Automatic data saving on
USB memory is not possible. Data must be saved manually on such media.
"I want to hook up to a LAN!"
No Problem!

■ Simultaneous recording on recording media (Memory function)
● Automatic data saving on CF card or HDD
● During high-speed sampling, data are written to internal
RAM first and later saved on other media
● During low-speed sampling, data are written to internal RAM
and sequentially saved on other media
● Highly suitable for long-term recording
* Available recording duration is determined by internal RAM capacity, not by
external media.
■ Maximum recording times with Memory function (auto saving)
• Saving to media in real-time is possible at sampling speeds of 100 ms/division or slower.
• Setting recording length to an arbitrary value allows increasing the 200,000 division limit up to a maximum of
320,000 divisions in 1 division units.

- Frequency area data analysis (FFT function) - Electrical distortion analysis/mechanical vibration analysis Function available from version 2.00 or later
FFT analysis function
Time domain
This function comprises single-signal FFT for tasks such as frequency
component analysis, dual-signal FFT for transfer function analysis,
and octave analysis for acoustic measurements. The signal source for
analysis are selectable from 1,000 to 10,000 data points.
Compared to the predecessor model 8841, processing speed is about
ten times faster when performing the most time-intensive analysis
Frequency domain
calculations under the same conditions.
FFT analysis from memory waveform data
Waveform in the MEM function
To use measurement data captured with the Memory function, the Jog & Shuttle
knobs serve to specify analysis points, and processing results can now be
displayed at the same time. Compared to earlier models such as the 8855 and
8841, operation has been significantly streamlined by eliminating the need to
Specify an analysis point
go back and forth between the Memory function and the FFT function. It is also
possible to view raw data measured with the Memory function and processing
results obtained from stored waveforms side by side. This makes it possible
to check the effects of window functions while viewing spectrum waveforms,
resulting in a dramatic improvement in operation convenience during use of the
analysis functions.
■ Recalculate by changing the number of calculation points after measurement
Even for measurement data currently based on a lower number of
calculation points, it is possible to increase the number later and
perform analysis again. For example, data measured at a setting of
1,000 points can be converted and reanalyzed with a 10,000 point
setting. This will result in a tenfold increase in frequency analysis
resolution. Of course, the opposite is also possible, going for example
from 10,000 points to 1,000 points.
* Recalculation with a different number of calculation points is not possible if frequency
averaging is set to ON.
1,000 points
Convert 1,000 to 10,000 points
■ Running spectrum display
Display ever-changing time-based spectrums in 3D and use the jog
and shuttle to load previously captured waveform. Data can be saved
as text for further graphical processing on Excel or other spreadsheet
applications.
■ Decibel-based scaling
Decibel-based scaling as requested by numerous customers
is now possible. There is no more need to make logarithmic
conversions on the side with an electronic calculator. The 8847
can accept input of overall values (power spectrum sum) in dB,
with the capability for easy scaling. Signals from noise level
meters and similar equipment can therefore be read directly.
