Introduction
The CoCo-80 (CoCo) is a handheld data recorder, dynamic signal analyzer, and
vibration data collector that is ideal for a wide range of industries including
automotive, aviation, aerospace, electronics, and military applications that
demand easy, quick, and accurate data recording and real-time processing in the
field. The CoCo is a low-cost, light-weight, battery powered handheld system with
unparalleled performance and accuracy. The user interface of the CoCo is
specifically designed to simplify its operation while maintaining the capability of
providing a wide variety of analysis functions.
The CoCo hardware platform supports two different software working modes:
Dynamic Signal Analyzer (DSA) and Vibration Data Collector (VDC). Each
working mode has its own user interface and operation navigation structure. The
DSA working mode is designed for mechanical structure analysis, testing, and
optimization for electrical, geophysics, and a wide range of other applications. The
VDC mode is dedicated to machine vibration data collection, analysis, and
trending. This manual will focus on the basic functions of the CoCo and EDM
used in DSA mode.
Figure 1: CoCo Hardware
The CoCo is the first battery powered handheld data acquisition system that
matches the performance and functionality of high-end systems. The CoCo is
equipped with 2, 4, 8, or 16 input channels and can accurately measure and
record both dynamic and static signals. The mass flash memory can record 8
channels of streaming signals simultaneously up to 102.4 kHz. An embedded
signal source channel provides various signal output waveforms that are
synchronized with the input sampling rate.
The CoCo utilizes a dual CPU architecture. An XScale CPU handles the user
interface, project configuration, power management, network communication,
and all the peripherals. A high-speed floating point DSP manages the data
input/output and real-time processing. The CoCo is also configured with large

CoCo-80 User Manual

amounts of RAM and NAND flash memory for mass data storage. Special thermal
and low power design elements eliminate the need for a cooling fan and increases
the battery operating time. Proprietary hardware technology delivers more than
130 dB of dynamic range for 2, 4, or 8 channel versions. The extremely high
dynamic range eliminates the need for multiple front end gain settings. The CoCo
can also be operated from a DC power source (which will simultaneously charge
the battery) with either the CoCo AC-DC Adapter (P/N CoCo-A11) or an
Automotive Cigarette Lighter Adapter (P/N CoCo-A03).
Revolutionary dual, parallel 24-bit A/D converters, digital technology, and unique
hardware designed for the CoCo offers more than 130 dB of dynamic range. The
high dynamic range and fidelity of the CoCo enables measurement of a wide
range of signals, regardless of the input signal magnitude.
Note: the 16 channel version has 100 dB of dynamic range
and utilizes selectable input voltage ranges of .1V, 1V and
10V pk-pk.
The CoCo excels in both dynamic and static measurements. When used for
dynamic measurements, the input channels offer extremely high-quality dynamic
range, signal to noise ratio, cross channel gain match, phase match, and spectrum
flatness over an analysis frequency range up to 46.08 kHz. When it is used to
measure static or quasi-static signals, it offers very high accuracy at DC or near
DC frequency.
For DSA applications the CoCo software stores and organizes the data in the
popular ASAM-ODS standard. Data may be exported to other data formats such
as UFF, BUFF, NI-TDM, ASCII, MATLAB, Excel, or WAV (exporting as WAV is
limited to time waveform data recordings). The ASAM-ODS data standard
provides ultimate flexibility and version compatibility. ASAM-ODS data standard
is widely supported by the automotive industry and is expanding to aerospace and
other areas.
The handheld system is equipped with two USB ports, a 100Base-T Ethernet, an
SD card interface, an audio input/output, a 5.7 inch color LCD display, and a
keypad. You can connect the CoCo to a PC, download files, and upgrade the
software through multiple types of network connections. The user interface of
CoCo is specifically designed for easy operation while it maintains the capability
of providing a wide variety of analysis functions.
The CoCo weighs less than 1.7 kg. Advanced thermal design eliminates the need
for a cooling fan reducing operating noise. The fully charged battery life is up to 8
hours, depending on configuration and usage. An AC adapter can be used at any
time to charge the device while simultaneously recording and processing data.

Compared to handheld data acquisition systems and signal analyzers from other
providers, the CoCo delivers higher dynamic range, accuracy, and recording
throughput rate, and real-time analysis performance. It also provides more
powerful communication peripherals.
Because the CoCo is a standalone instrument it does not have the same
drawbacks common to PC-tethered data acquisition systems and analyzers, such
as unreliable data transfer. The CoCo does not need any additional PC or laptop to
operate during field data acquisition. Hence the CoCo-80 is much more reliable
and easier to operate.

Engineering Data Management (EDM) is PC software used for data management,
post signal processing, viewing, reporting, and connecting Crystal Instruments
hardware, the PC, and the data storage system. EDM provides connectivity to one
or more CoCo or Spider devices. It provides data management tools to search
through many tests and records, and view file properties or waveform
characteristics. The analysis tools display data in a wide variety of formats and
configurations to help identify important signal characteristics using cursors. The
report tool documents the hardware configuration or data analysis results in a
user formatted document.
EDM has two working modes for use with CoCo:
CoCo-80 DSA mode: access CoCo-80 in its DSA mode, download,
and view data files. CSA Editor, a tool for editing CoCo testing
projects, will be included in this mode. This manual will cover
information on the basic CoCo DSA functions.
