Mouse Operation Terminology
Accuracy
We define measurement tolerances in terms of f.s. (full scale) values, with the following
meanings:
f.s. : maximum display value or scale length
In this instrument, the maximum displayable value is the range (V/div) times the number
of divisions (20) on the vertical axis.
Example: For the 1 V/div range, f.s. = 20 V
Indicates that incorrect operation presents an extreme hazard that
could result in serious injury or death to the user.

Chapter 1 Overview
The Model 8860 and 8861 Memory HiCorders are data recorders that provide a
broad range of measurements for observing both high-speed waveforms and
low-speed signals.
Various measurements including voltage, current, temperature and frequency
are available using connection cables or sensors with optional input modules. Up
to four input modules can be installed in the Model 8860, and up to eight in the
8861.
Also, optional storage memory can be installed to enable long-term recording
with high-speed sampling.
With the LAN interface installed as a standard feature, remote control and data
transfer to personal computers can be performed simply over a network.
By installing the optional thermal printer, waveforms and screen image copies
can be printed at large sizes.
For easy operation, a mouse and keyboard can also be used.
In addition to pre-existing input modules (Models 8936 to 8947), the following
new input modules support recording of many types of parameters:
• Model 8956 Analog Unit: Provides 20 MS/s waveform recording with 12-bit
resolution
• Model 8957 High Resolution Unit: Provides 2 MS/s waveform recording with
16-bit resolution
• Model 8958 16-Ch Scanner Unit: Provides temperature and voltage measure-
ment on multiple channels with 50 ms recording interval
• Model 8959 DC/RMS Unit: Provides RMS waveform recording
• Model 8960 Strain Unit: Provides 200 kS/s distortion measurement with 16 bit
resolution.
See "Chapter 1 Overview" in the Input Module Guide
Floating analog input components enable inputs to be connected to points with
different potentials.
Analog signals from input modules and logic signals from logic probes can be
recorded simultaneously.
The high resolution (800 × 600) 10.4-inch TFT color LCD ensures clear visibility.

Memory Function:
Provides a sampling period as fast as 50 ns, suitable for observing instanta-
neous waveforms and transient phenomena.
Recorder Function:
Suitable for slow phenomena and observational recording.
Real-Time Saving Function:
Suitable for storing long-term measurement data. While measuring, data is
saved directly onto recording media.
FFT Function:
Provides frequency analysis.

About FFT Function: Analysis Supplement
8860: Choose from 32 to 128 MWords, 512 MWords or 1 GWord.
8861: Choose from 64 to 256 MWords, or 1 or 2 GWords.
Digital triggering circuitry is employed.
Control measurements by combined trigger criteria including level, window,
period, glitch, slope, voltage sag, logic (pattern) and timer triggers.
See "Chapter 6 Trigger Settings" (⇒p. 129)
By setting the measurement unit name and physical value per volt of input sig-
nal, measurements are converted and displayed as the specified measurement
units.
See "5.4 Converting Input Values (Scaling Function)" (⇒p. 117)
Without interrupting ongoing measurements, you can scroll back to view
recorded waveforms that have scrolled off the screen.
See "8.1 Scrolling Waveforms" (⇒p. 186)
Numerical values and gauges can be displayed with waveforms, simplifying on-
screen verification of measured values.
See "8.5 Applying Gauges" (⇒p. 191)
Trace cursors enable viewing times and numerical values on all channels.
