Experience The Cadwell Difference – Since 1979

The benefits of owning a Cadwell system are numerous. Our development team understands
and delivers what you need. Everyone at Cadwell stands behind our products, and we all have
the same goal - to keep you as a loyal, devoted customer long into the future.

Innovative Neurodiagnostic Instruments

John Cadwell, BSEE, MD designed the first microprocessor-controlled EMG instrument. In

1979, he and his brother Carl, DDS, formed Cadwell Laboratories, Inc. and began selling
their device. Since then, Cadwell has been a leader in the development and manufacture
of innovative and reliable instruments for neurophysiology. Many of these instruments
have been providing decades of service to their owners.

Numerous patents are held by Cadwell, including those for magnetic stimulators, cable
shielding designs, neural network analysis of EEG, and database designs. Today, still
located in Kennewick, Washington, John and Carl continue ownership of the company and
come to work everyday to develop and market products ranging from EMG to EEG to PSG
to IONM instrumentation and more. Cadwell has a firm hold of its identity and a dedicated
focus on neurophysiology.

Our Most Advanced EMG/EP Instrument (The New Standard)
The Sierra® Summit™ is the latest in a long line of successful Cadwell products. It combines the Sierra Wave’s ease of use with
innovative advancements in acquisition and stimulation technology to offer the most flexible, reliable and clinically functional
system on the market today. The Summit is offered in either a 2, 6, or 12 channel configuration and is proudly designed
and manufactured at our Kennewick, Washington facility. The Summit is built with the same lasting quality and reliability
customers have come to expect from Cadwell.

The Summit can be configured as a portable or desktop system. The portable version comes with a laptop computer and
soft-sided carrying case. The desktop version comes with a desktop PC and an LCD monitor or all-in-one PC. We offer both
lightweight and hospital-grade equipment carts to complete the system.

Cart Configurations
Point-of-Care
Shown here is a 2-channel Sierra Summit with a laptop computer on the lightweight Point-
of-Care cart. A printer can be placed on the shelf and supplies stored in the bin. Mounting
brackets for an amplifier arm are located on either side of the top shelf. The articulated
arm holds the amplifier, StimTroller Plus and also provides a convenient needle holder. The
placement of the stimulator and needle holder can be reversed. Snap-on cable covers on
the arm protect the amplifier and stimulator cables while providing a clean appearance.
The top shelf height is adjustable via hydraulic lever for use while standing or
sitting. Options include a pull-out keyboard shelf, footswitch holder and an
additional storage bin.

Narrow Trolley
Shown here is a 12-channel Sierra Summit with a low profile PC on the
Narrow Trolley cart. This cart features a foam handle and large locking
wheels for easy manuevering. Cable management is provided inside the
trolley’s twin legs. The PC and a printer can both be placed on the large
bottom shelf. The middle shelf holds the Sierra Summit base unit, while
the top shelf remains free and can be used as a convenient writing
surface. The LCD monitor mounts on a sturdy, adjustable pole on
the rear of the top shelf. An optional isolation transformer can be
installed on the basement shelf. Other options include a pull-
out keyboard/mouse tray, storage drawer and an accessory bag
which mounts on the back of the cart.

Don’t need a cart? The Sierra Summit, amplifier,

StimTroller Plus and cables all fit into our custom
carrying case. For even greater
portability, upgrade to the wheeled
carrying case.

Maximize your diagnostic offerings by configuring Easy III EEG and
Sierra Summit EMG/EP software on the same PC. Pictured here are
the 12-channel Sierra Summit and 32-channel Easy III amplifiers on a
Narrow Trolley cart. An all-in-one computer frees up the bottom shelf
for a large printer or additional storage space.

Hardware Diagnostics
The Sierra Summit includes a comprehensive hardware
diagnostic suite. Reduce troubleshooting time by easily
verifying the proper performance of the amplifier, electrical
stimulators and base unit keypad. You can save or print the
test results for your maintenance notebook. Calibration
signals, with four voltages and two frequency settings, are also
available in all test protocols.

Amplifiers
Cadwell has long been recognized as producing some of the world’s finest
neurophysiologic amplifiers; and the Sierra Summit amplifiers are no exception.
Either 2-, 6-, or 12-channel configurations are available. The same amplifier is utilized for
the 6-channel configuration, with the maximum number of channels limited by software.
Each amplifier features fast artifact recovery and very low noise. Analog-to-digital
conversion is done inside the amplifier, eliminating the amplifier cable as a potential
noise source. Each amplifier has superb RF immunity and excellent signal quality.
Temperature measurement, impedance, on/off switch and calibration signals are built-
in. The 12-channel amplifier has four non-switched and eight switched channels. The
eight switched channels can use any of the 20 inputs available in the modified
head pattern on the amplifier or optional remote input box. All 12 channels
can be used simultaneously for data acquisition.

A unique electrode continuity check

(Electrode Check) is built into each
amplifier, so you can easily confirm if
one of your electrode leads is good
or bad.

 CadLink™ Database

Designed for easy setup and operation in either the private practice or large neurodiagnostic laboratory setting, the CadLink
database organizes, manages and secures your patient files and customized user settings. View your patient records in multiple ways
- alphabetically, by day, by month, by year, by physician - whichever is convenient. Complex searches can be accomplished using the
advanced search capabilities. Import supplementary documentation, such as symptom drawings, pictures or patient history forms and
save them with the record. CadLink supports multiple users; each with their own test settings and report templates.

Networking
Add the CadLink Central Server module and you can seamlessly network multiple Sierra Summits and Reader stations. Patient
records are available from any acquisition or review station on the network. Complete the exam and then finish the report later in the
comfort of your office. The receptionist can also be included on the network so that patient information can be input at check-in or
final edits can be made to reports. Change a test setting or report template on one Sierra Summit and it is automatically available to
all systems on the network.

Your Time is Valuable
Here Are Three Reasons the Sierra Summit Will Save You Time
1. Reduced Testing Time
• Perform NCV, F/H tests without touching
the keypad.
Select nerves, acquire traces, store traces, and enter
distances using programmable buttons on the StimTroller Plus.

• Easier access to stim locations.

Angle of stimulus probes is adjustable and the
polarity of the probes is reversible. And with our
Quick Connect Adapter, you don’t need to
remove the probes to attach a bar or ring electrode.

• Eliminate the time of moving between screens.

Study lists allow you to perform a complete study from
one screen, saving button pushes and time.

• Adapts to your testing style.

Most functions can be performed using button pushes or the
mouse. You decide which makes you more efficient.
2. Rapid Review of Results
• One button push displays all data.
Numbers and waveforms from every
test are available from one screen. Click
on a test to review the waveforms or
adjust cursors.

• Faster data review.
