A/D
conversion
Using the same operating principle as a digital oscilloscope, data is recorded to
the expanded internal memory at high speed. Sampling rate is up to 20 MS/s
(50-ns period) for all channels simultaneously. Capture unpredictable operating
anomalies and transient waveforms.
n Records to Solid-State Memory
Because instruments that rely on disk access such as hard disk drives are sus-
ceptible to vibration, they are often unsuitable for on-board measurements.
MEMORY HiCORDERs are preferable for on-board testing because they write
data to solid-state memory with no moving parts. You can back up data to a PC
Card or USB storage device when finished measuring. When the optional mem-
ory backup unit is installed, the instrument’s internal memory data is preserved
when power is turned off.
n All Channels Isolated, 20 MS/s Sampling
Except when using the Scanner Module, every input channel has
its own A/D converter. Because all channels are sampled simul-
taneously, transient waveforms can be easily observed along with
signals. The Scanner Module switches all inputs through a single
A/D converter, but even in that case, all channels are isolated.
n Large Capacity Internal Memory
Both high-speed write capability and a large memory capacity are
provided to support high-speed sampling. Total memory capac-
ity ranges from 32 megawords to 1 gigaword, enabling capture
of waveform peaks by high-speed sampling, as well as long-term
recording and long-period waveform capture. (Model 8861-50 provides
twice the memory capacity, but with the same recording time limits.)
n An Actual Waveform
Measurement Example
For operational analysis of an inverter, the waveforms of the high fre-
quency switched carrier and the low frequency fundamental both need
to be observed. High-speed sampling, long-term memory recording
and input isolation make these observations possible. Various HIOKI
non-contact clamp-on sensors capable of measuring up to HF ranges
can be used to observe current waveforms.
CLAMP ON PROBE 3270 Series provides flat electrical
characteristics for observing current waveforms over a
remarkably broad range of amplitudes from mA order to
500 A at frequencies from DC to HF.
Memory Function for High-Speed Waveform Monitoring
Three-Phase Inverter Output Circuit
(Because emitter voltage for each phase is different, isolated measurements are essential.)
n Internal Memory Division (Segmentation) Function
Internal memory can be segmented for use into 4,096 blocks. By
using “sequential save” to write data to the segmented memory,
the waveform in any block can be overlaid with that in a reference
block for comparison.
n External Sampling Input Capability
The sampling rate for memory recording can be synchronized to
an external clock signal (up to 10 MS/s). So, for example, sampling
can be synchronized to the rotation cycle of an engine.
Reliably capture waveform anomalies buried within normal signals

n High-Voltage
Measurement
Measuring in situations where high voltage exists between channels,
such as three-phase inverters, requires a measurement instrument that
has all input channels isolated. In addition, when measuring signals
such as those of switching circuits that include common-mode volt-
age with a high-frequency component, the isolated circuit’s common-
mode frequency rejection characteristics can greatly affect measure-
ments. To measure these kinds of voltages, you can use the HIGH
VOLTAGE UNIT 8961 or the optional DIFFERENTIAL PROBE 9322 for
CAT III 600-volt AC and DC maximum ratede voltage to earth.

Capture High-Speed Signals by Triggering During Slow Recording
- New REC&MEM Function and Real-Time Saving -
n Transient waveform recording that is impossible with a pen recorder
The new REC&MEM function can record high-speed waveforms such as inter-
mittent noise by applying a trigger while recording long-term fluctuations just
like a pen recorder. This type of measurement previously required choosing
between the Recorder function (for slow trend graph recording), or the Memory
function (for high-speed oscilloscope-style recording). Now both types of wave-
forms can be recorded simultaneously using the REC&MEM function.
n Recording an Entire Waveform Anomaly
The Real-Time Save function writes measurement data to the specified des-
tination during measurement, enabling long-term measurements indepen-
dent of the instrument’s installed memory capacity. The destination storage
media may be the internal hard disk, a PC Card or a shared network folder.
Simultaneously, overall measurement data
(the whole waveform) is recorded in the
instrument’s internal memory, which is then
saved to the storage media when measure-
ment is finished. For analysis, specify the
range to be analyzed from the overall wave-
form data, and reload it. The reloaded data
is used with the Memory function for wave-
form and numerical calculations, or with the
FFT function for FFT analysis.

n Operating Principle of the Recorder Function
With the Recorder function, only maximum and minimum values
of the data sampled within the specified timebase are written to
memory, so each recorded data point consists of a pair of values,
with 100 such points recorded for each waveform timebase division.
Because of this, the volume of recorded data is compressed while
following steep fluctuations of the measured input voltage.
Note: When data recorded with the Recorder function is viewed on a PC, both
minimumandmaximumvaluesappearasatimeseriesofdatapoints.

Waveform Observation While Recording
n Changing Compression and Zooming While Measuring
Models 8860-50 and 8861-50 support changing the compression ratio, turning
the zoom function on and off, and scroll-back display while measuring, so you
can view and analyze existing measurement data without having to wait for the
measurement process to finish.
n
Scroll-Back Display
An earlier portion of the waveform can be viewed without interrupt record-
ing. This function automatically displays earlier parts of the waveform just by
turning the Scroll knob counterclockwise. Click the Scroll Trace button on the
screen, to return the display to the current waveform position.
Sheet Display Function
The Sheet function has been introduced to support multi-channel
measurements (each sheet shows 32 channels). Different display
formats can be selected for each sheet, so that each sheet can be
assigned and analyzed for a particular application.
The Next Generation Hybrid Recorder
- A single instrument provides both oscilloscope and data logger functions -
Installing a Scanner Module Creates a Multi-Channel Data Logger
Recording slowly changing physical values such as temperature has been per-
formed by plotting recorders and hybrid recorders (combined numerical value
and analog graph recording), and is currently performed by data loggers. On
the other hand, for high-speed waveform observation, only an oscilloscope (or
MEMORY HiCORDER) can be used. However, because the demands of mea-
surement sites can vary, having both of these functions in a single instrument
can be advantageous.
MEMORY HiCORDER Models 8860-50 and 8861-50 and Scanner Unit 8958 are
the answer to customers’ needs.
The waveform scrolling direction can be switched between vertical
and horizontal. You can also view a continuously scrollable display to
confirm a whole long-term waveform without time-axis compression,
while simultaneously displaying time series’ and X-Y plots.
n Economical Cost per Channel
The Scanner Module switches 16 input channels through one A/D convert-
er. Of course all channels are isolated. Cost per channel is thereby remark-
ably reduced when compared to systems that include an A/D converter for
every input channel. Installing four Scanner Modules in the 8860-50 pro-
vides 64 measurement channels, and installing eight Scanner Modules in the
8861-50 provides 128 measurement channels.
n Dual-Timebase Sampling at High and Low Speeds
Depending on customers’ applications, there are cases in which high-speed
signals need to be captured as waveforms while measuring multiple chan-
nels with a Scanner Module. Both types of signals can be measured by using
a scanner module together with a common high-speed analog module, and
recording with two different timebases. Two waveforms are displayed and
can be monitored on the same time axis.

Trigger during capturing and search after capturing
The trigger function allows you to set diverse parameters to detect
a particular waveform anomaly during capturing. Setting the pre-
trigger mode allows you to monitor the pre-trigger waveform. This is
useful for analyzing the cause of the anomaly.
On the other hand, the search function allows you to detect an anom-
aly after all data is captured. This allows you to search for and display
an anomaly in the same manner as with the trigger function.
When a waveform is unpredictable and setting a parameter during
measurement is difficult, it is recommended to use the search func-
tion to locate an anomaly after capturing.
n Capture a sudden power loss with the drop trigger
Set the voltage drop trigger to capture a sudden power loss resulting from a blackout
caused by lighting or a circuit breaker tripping.
Set the window out trigger to capture an impulse noise or surge noise (voltage swell)
caused by, for example, the solenoid opening and closing.
Set multiple triggers on a single channel
Unlike with conventional MEMORY HiCORDERs, the 8860 series
allows you to set multiple trigger parameters on a particular single
channel. This allows you to set, for example, the glitch trigger, level
trigger, window-out trigger, voltage drop trigger, window-in trigger,
and on the same input wave-
form to monitor it. (8 parameters
in the 8860-50 and 16 param-
eters in the 8861-50 can be set.)
n Stop trigger for the MEM function
Unlike with conventional MEMORY HiCORDERs, a stop trigger is supported. This
enables the timing of measurement to be controlled for both the MEM and REC
functions. This also allows you to set Start or Stop independently for each trigger
source, thus enabling the timing of measurement to be controlled in a variety of com-
binations. (Start or Stop trigger can also be set to the logical source.)
n Slope trigger
Unlike with conventional MEMORY
HiCORDERs, a slope trigger is supported.
This allows you to monitor a noise super-
imposed on periodic waveforms such as
a power waveform. This also allows you
to monitor a rapid change in temperature
with the amount of change in slope instead
of level.
n Edge detection and level detection of the logic trigger
Unlike with conventional MEMORY HiCORDERs supporting only
edge detection, the Models 8860-50 and 8861-50 supports level detec-
tion of the logic trigger. This function causes the trigger to be activat-
ed when a specified pattern occurs, even if the logic pattern condition
is not met after the start of measurement.
n Set the event times independently for each trigger source
* For the analog trigger only
Unlike with conventional MEMORY HiCORDERs, this
allows you to set the event times independently for each
trigger source, thus enabling the setting of trigger condi-
tions in a variety of combinations.

n Change the settings on the DISP screen
The dialog bar on the top of the DISP screen (waveform monitor-
ing screen) allows you to change the settings.
The frequency resolution and capture time are also displayed.
FFT analysis function
The single-channel FFT function is used in spectrum analysis. The two-
channel FFT function analyzes transfer functions. The octave analysis func-
tion is used in acoustic analysis. The signal source for FFT analysis is a sec-
tion obtained from the waveforms captured in the MEM function (the required
number of pieces of data for FFT analysis are 1000 to 20,000 points). The
calculation speed for the same condition (when performing the most time-con-
suming analysis) is about ten times faster than with the conventional Model
8855.
n Simultaneously perform up to 16 calculations
Unlike with the conventional HIOKI 8855 and 8841 models that
allow for the simultaneous performing of up to two calculations,
the 8860-50 and 8861-50 models allow for the simultaneous
performing of up to eight (four times more) FFT calculations for
analysis. Furthermore, the analysis channel can be selected inde-
pendently.
n Split screen (a total of 14 patterns)
You can select a split screen for-
mat according to your needs. For
example, the MEM and REC func-
tions allow you to select a different
split screen format independently for
each sheet. Unlike with, for example,
the conventional 8855 and 8841
models, a function to display super-
imposed graphs is also supported
(however, the function depends on the analysis
mode).
n A variety of window functions
Unlike with the conventional 8855 and 8841 models that sup-
port only the three window function options “Rectangular,”
“Hanning,” and “Exponential,” the 8860-50 and 8861-50 mod-
els include four additional options, thus enabling you to select
a window function from a total of seven options. Furthermore,
a difference in calculation results of line spectrum between
other companies’ FFT analyzers and HIOKI’s analyzer can be
compensated by selecting the energy attenuation compensation
method when using a window function.
n Phase Highlight Display
Phase Highlight emphasizes on the display only those parts of a
waveform that exceed a certain level, in order to acquire a power
spectrum in the midst of phase calculation. The figure shows
power and phase spectra at the same time when the highlighted
display is enabled, so you can easily see important parts of the
waveform that are normally difficult to see because they appear
like noise.

Perform FFT calculation on the waveform from the MEM function
When performing FFT analysis on the data obtained by measurement with the
MEM function, you can use the jog shuttle to specify an analysis point and view
the calculation results on the same screen. Unlike with the conventional 8855 and
8841 models, you do not need to switch between the MEM function and FFT func-
tion screens to set the starting point of calculation. Furthermore, the display of “Raw
Data” obtained by measurement with the MEM function and the calculation results
of“StorageWaveform”onthesamescreenallowsyoutoviewtheeffectofthewin-
dow function and the spectrum waveform on the same window, thus greatly enhanc-
ing operability for analysis.
Power spectrum density
You can obtain a power spec-
trum per Hz when analyzing
signals spread over a wide area,
such as noise.

The most appropriate spec-
trum is estimated using the
statistical method.

n Rich Analysis Capabilities
Power Spectrum Density and LPC Analysis have been added to
the calculation selections, for measuring power spectrum per Hz
and spectral envelopes. As for calculation settings, former con-
cepts such as “Channel Modes” have been eliminated, and chan-
nel settings are now automatically set according to the selected
calculation type, eliminating otherwise complex settings.
n Change the count of calculation points and perform re-calculation
after measurement ends
After measurement is performed using less calculation points, you
can change the point count and perform re-analysis. For example, if
you perform measurement using 1,000 calculation points, you can
then convert point count to 20,000 to perform re-analysis on the data.
In this case, the frequency resolution increases 10 times. Needless to
say, you can convert the point count to 1,000 to perform re-analysis
on the data obtained by performing measurement using 20,000
points.
*Re-calculationbychangingthepointcountcannotbeperformedwhenMeanFrequencyissettoON.
n Scaling in “dB”
The long desired capability to scale in dB is supported. You no
longer need to perform logarithmic calculation holding a calcula-
tor in one hand. The 8860-50 and 8861-50 models allow you to
enter the overall value (sum of power spectrum values) in dB,
thus making scaling easier. This enables
signals to be easily read directly from, for
example, a noise meter.

n To access the shared folder:
Enter the host name of the computer on the file screen of the 8860-50, enter the user
name and password in the account field, and then select the folder you want to share.
n Restrictions
Automatic saving during measurement is restrict-
ed to 1ms/division or more of the time axis. Also,
restrictions to the time axis settings differ depend-
ing on the scanner module, number of channels,
storage media, and setting conditions for real-time
printing.
n Remote control and automatic saving to a shared folder
The 8860 series allows for remote control using
the Internet browser on the computer. When you
register access to a shared folder on a computer on
the network, you can store and load data to and from
the shared folder on the 8860-50 or the 8861-50 file
screen.

With the Windows-style interface, you can easily make set-
tings and adjustments with the click of a mouse, and enter
text and other com-

common PC.
n USB Ports and External Monitor Output
Three USB 2.0 ports are now provided to support commonly available
PC peripherals. A VGA D-sub output connector is also included to
support viewing the measurement screen on an external monitor.
n Automatic saving during measurement
Unlike with conventional MEMORY HiCORDERs, the 8860
series allows automatic saving during measurement.
n
Redundancy against errors in the storage destination
The 8860 series allows you to set up to two storage destina-
tions. Even if, for example, an overflow error occurs on a PC card during
automatic saving, switching to the second backup storage destination
takes place automatically to ensure saving continues.
n Set 16 groups of numerical calculations
Unlike with conventional MEMORY HiCORDERs, the 8860
series allows you to set 16 groups of numerical calculations.
Furthermore, each group allows you to select 16 calculation items
from a total of 19. The SUB MENU screen of the waveform
screen also allows you to view and change the numerical calcu-
lation settings and perform recalculation. This enables the set-
tings of calculations in each group on the waveform screen to be
changed and monitored, thus enhancing operability.
n Simultaneously display timeline and XY-axis composite waveforms
The 8860 series uses a split screen to support the simultaneous
display of “timeline waveform” and “XY-axis composite wave-
form.” Any channel can be set to the X-axis and Y-axis. The
MEM function supports XY-axis waveforms. Models 8860-50
and 8861-50 can display sixteen X-Y plots simultaneously.
