MEMORY HiCORDER 8855
Digital Oscilloscope
For analyzing power control system operation, digital circuits, and transient power
Extended memory! An oscilloscope with 8 isolated channels
High-speed sampling and expanded memory are essential for simultaneously observing switching carrier waveforms and basic waveforms. Furthermore, greater memory has been requested by users to allow measurement of sporadic and unpredictable events and signals that cannot be triggered. The 20 MS/s high-speed sampling and a memory capacity of up to 512 megawords (1 GB, optional) of the MEMORY HiCORDER 8855 makes it the best-equipped isolated digital oscilloscope on the market, and the ideal instrument to search for and analyze anomalous waveforms.

For operation analysis of power control systems such as inverters
- Application Examples Inverter switching waveforms Automobile research and development
The 8855 can be used to observe various inverter waveforms. To provide stable measurement of voltage waveforms, the 8855 uses high-frequency, noise-resistant CMRR and maintains high floating voltages with isolated inputs. When observing current waveforms, you can install a special amplifier unit for current measurement that allows you to use a supersensitive, broadband clamp-on probe to perform measurements without breaking the electric circuit.
All measurement data can be stored in installed internal memory. Because of the large amount of free memory, you can acquire waveforms over an extended period.
When performing engine characterization analysis, the 8855 is ideally-suited to measuring waveforms derived from boost pressure, oil pressure, air-fuel ratio, ignition timing, rotation speed, or injector opening. The 8855 also has an expanded memory for storing large quantities of data taken in various conditions. The 8855 can be used to observe pressure waveforms, such as those for fuel injection lines or jet pumps, and then compare them with standard waveforms.
Voltage, current, temperature, pressure, vibration, rotation speed, etc. Engine
I want to observe carrier and basic waveforms simultaneously with high-speed switching, such as inverter waveforms 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.
I'd like to view waveforms that occur during the 5 seconds after the power is turned on and the device stabilizes I want to record data for all sporadic abnormalities that occur during automobile testing without using triggers In response to these requests, the MEMORY HiCORDER 8855 supports large-capacity memory, which can be expanded to up to 512 megawords (1 GB). Even at a sampling rate of 20MS/s, the 8855 can record for up to 12.8 seconds (2 channels, with a maximum of 256 megawords/channel) of data.
Compatible with F/V and temperature input
Use the optional F/V conversion input unit to observe control and rotation signals as waveforms, or the temperature input unit for thermocouple measurements. Depending on your application needs, select from a wide array of input units to configure your ideal measurement system.
Zoom function
When observing waveforms using an analog oscilloscope, you can slow down the sweep rate to view the entire waveform or speed it up to zoom in on the waveform. However, you can only observe enlarged waveforms following a trigger point. As you observe waveforms, you can use the zoom function to enlarge selected points on the waveforms.
Recorder and memory function
(available from version 2.00 of this unit)
When recording envelope waveforms in recorder mode, the 8855 can be used to capture sporadic signal waveforms in memory mode.
20 MS/s high-speed sampling for all channels using isolated input
- Functions Can I use the 8855 to measure high voltages, such as inverter output ?
When measuring the difference in electrical potential between two signals that have a large overlapping common mode voltage, electric shock may result if you are not using a measurement unit with completely insulated input channels like the MEMORY HiCORDER 8855. Further, when measuring signals with a superimposed common mode voltage that includes high frequency components, such as inverter control and switching power circuit signals, the frequency characteristics for the common mode removal comparison of the insulated area greatly affect the measurement results. For example, when using the ANALOG UNIT 8950, the peak-to-peak value for all waveform data can be measured or displayed in a range configuration of up to 280 V RMS using the memory function. If you want to measure voltages that exceed 280 V, you can use the optional DIFFERENTIAL PROBE 9322 to measure voltages up to 2000 V DC or 1000 V AC. Because a maximum voltage to ground of 1500 V AC/DC (CAT II) is possible, you can measure the common mode voltage for larger systems than before.

Using the DIFFERENTIAL PROBE 9322
The POWER CORD 9328 (when connected to the power plug of the 9322 and the 12-V output connection of the input unit)
Three-phase inverter output system
(Since the electric potential of the emitter is different for each phase, floating measurement is indispensable.)
Measuring the surge noise for power lines (using the DIFFERENTIAL PROBE 9322 in AC mode)
If you select AC as the output mode, the signal connected to AC is divided to 1/1000 inside the probe and output. Because the frequency range can be set between 1 kHz and 10 MHz, the output waveform is displayed only when a voltage signal that includes a high waveform component is input, such as surge noise superimposed on a 50/60 Hz commercial power line. Therefore, the 8855 can be used primarily to detect noise, as well as to measure the height of waves.
Rectified RMS voltages can be output (using the DIFFERENTIAL PROBE 9322 in RMS mode)
When RMS is selected as the output mode, the input signal voltage is divided to 1/1000, then true RMS value rectification is performed, and the DC voltage output. RMS value rectification is performed by analog circuitry, and because the bandwidth extends from 40 Hz to 100 kHz, signals that include harmonic components can be accurately converted to RMS values not only for 50/60 Hz commercial power lines, but for other waveforms containing harmonics, such as inverter output waveforms.
Can I observe distorted current, such as that of inverter output ?
Observation of distorted current is possible when using the 8855 in combination with the VOLTAGE/CURRENT UNIT 8951 and a clamp-on probe or clamp-on sensor. Especially when using the CLAMP ON PROBEs 3273-50, 3274, 3275, or 3276, you can accurately observe current waveforms ranging from very small to very large with a highly linear response for current frequencies from DC voltage to high frequencies.

Using the trigger function during data capture and the trigger search function after data has been captured
The trigger function allows you to set various conditions for input waveforms in order to capture waveform anomalies. It is convenient for analyzing the causes of anomalies, since a pretrigger can be set, enabling you to observe waveforms before starting the trigger search. In contrast to above, this function allows you to search for and display anomalous waveforms in captured data using the same criteria used for the trigger function during measurement. If triggers cannot be set during measurement because you do not know what sort of waveforms will be displayed, you can search for anomalies using the trigger search function once all of the data has been captured.
This mark indicates the trigger point.
Use the 8855 to capture power line noise:
In order to capture events such as impulse noise caused by lightning strikes and the opening and closing of solenoids, and voltage surge noise (voltage swells) caused by switching power lines with heavy loads, the 8855 comes equipped with window out trigger and glitch trigger functions.
Use the 8855 to capture instantaneous power outages on power lines:
Using the window out trigger and trigger filter functions, you can capture instantaneous power outages due to events such as lightning strikes and breaker trippage due to short circuits.

Perfect for inspecting storage media such as CDs, MOs, DVDs, and HDDs
- Application Examples Analyzing operation of digital A/V equipment
When equipped with its maximum memory capacity, the 8855 is useful for designing and analyzing digital A/V, communications, and informationrelated 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.
Observing signals from magnetic data
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.

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.
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)
1 MS/s and 16-bit high resolution
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.
Sequential saves assures minimal dead time
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 during sequential saves means that continuously occurring triggers are not missed. (Minimum setting of approximately 1 ms)
FFT function
(available with version 2.00 of this unit)
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.
Complete data capturing with a large capacity 1 Gbyte memory (optional)
- Functions How long can I record to the internal memory ?
The 8855 comes equipped with a standard memory capacity of 32 Mwords, but you can increase this by four times (128 Mwords total) or as much as 16 times (512 Mwords total) by using the optional memory available. The maximum recording times are displayed in the table on the right according to the time axis range setting.

Calculation function
Waveforms captured in memory mode can be processed through such operations as the four basic arithmetic operations, as well as differentiation and integration. Furthermore, maximums and other parameters of the observed waveform data can be displayed. Using this function, signals can be analyzed in a many different ways.
Waveform judgment function
After defining a reference waveform area, you can use area judgment to check whether the waveform displayed on the screen extends outside that area. With parameter judgment, you can evaluate results of numeric calculation with set values.
Scaling function
Actual measurements usually involve parameters other than voltage. Therefore, various physical parameters such as speed, vibration, or temperature commonly need to be monitored. In such measurement conditions, the scaling function can be used to automatically convert to the desired parameter.
Scaling
X-Y waveform display
The 8855 allows you to observe X-Y composite waveforms (Lissajous waveforms) that occur between two signals. Any channel can be set as the X or Y axis. In addition to its composition capacity in memory mode, the 8855 can display real-time images of unlimited recording time in recorder mode.

Measure Power Abnormalities During Power ON/OFF or Load Fluctuations
Introducing Power Monitoring Using the FUNCTION UP DISK 9549
Voltage, current, and power waveforms on the secondary side of an inverter Display of power and other parameters (calculated)
By installing the power monitor function in the MEMORY HiCORDER 8855, you can monitor power transient waveforms and view power trend graphs. Use of this function requires the optional FUNCTION UP DISK 9549, which is sold separately. Input units that can be used with this function are the ANALOG UNIT 8950 and the DC/RMS UNIT 8952. For current input, you can use either the VOLTAGE/CURRENT UNIT 8951, or the CLAMP ON PROBE 3273-50/3274/3275/3276. (The 9270 Series can also be used.)
Calculated power results for all acquired waveforms or the span selected with the A-B cursors can be displayed on the screen as a list. A full 4 channels are available for each of voltage and current, allowing measurement of one 3-phase, 3-wire system, or one single-phase, 2-wire system. Calculated results can be displayed either as numerics only (as shown above), or as a numeric overlay in a waveform screen like that shown at left.
Excess power during inverter power-on operation
Power Measurement Settings Screen
You can display a variety of waveforms accompanying inverter startup, including transient (excess) power waveforms and trend graphs (fluctuation waveforms). Together with its noise-resistant CMRR characteristic, the high floating voltage maintained by the 8855's isolated input assures stable observation of voltage waveforms. Observation of current is possible using the 8855 in combination with the appropriate voltage/current input unit and a clamp-on probe or clamp-on sensor. This makes it easy to measure power surges occurring when power is turned on that cannot be measured with ordinary power meters.
There is no need to set up complicated operations, such as calculations for waveform processing involving the memory function. All that is needed is to select the connect mode and a waveform type of either instantaneous or variable. A connection check function is provided to help you determine whether the connection method is correct.

Power monitor function
(installed as an option) This function works with the single -phase t wo -wir e, single - pha se thr e e -wir e, thr e e phase three-wire, three-phase four-wire and DC connection modes, making it possible to measure systems ranging from four singlephase two-wire systems, to a combination of one three-phase four wire system + one singlephase two-wire system. Calculations can be performed on partial waveforms selected for all waveforms in storage by using the A-B cursors, and results can be displayed in a single screen. Numeric results can be displayed as overlays in the waveform screens.
Instantaneous power waveform display
(power monitor function) This function multiplies captured voltage and current waveforms and displays the result as an instantaneous power waveform. (Display in real-time is possible through hardware integration processing for speed ranges up to 10 ms/DIV. For faster ranges, power waveform display is calculated after first storing waveforms in memory.) Power waveform display allows up to 8 waveforms to be displayed in addition to voltage and current waveforms, and a total of up to 16 waveforms can be displayed simultaneously (8 voltage/current channels, and 8 power waveforms). Using the appropriate input units, values such as temperature and frequency can be simultaneously observed on channels for which power calculations are not being performed.
Trend graph display
(power monitor function) Using this function, you can do calculations using voltage and current waveforms stored i n m e m o r y, a n d d i s p l a y t h e r e s u l t s a s voltage, current, or power trend graphs. This enables you to per form detailed analyses on the transient power segments, such as when a device is powered on or during load fluctuations.
