SynAmps RT Highlights

Headbox-Based Amplification – Analog signals, whether buffered or not, are susceptible to noise. With the SynAmps RT, signals are amplified and digitized right at the patient side, providing a digital signal transmission path and providing the very best signal integrity.

70 Channel Headbox Units – Allows you to use ALL of your channels. The SynAmps RT offers two external auxiliary and four bipolar inputs in addition to the standard 64 channels per headbox. You don’t have to convert bipolar channels to monopolar to get your full montage.

Check Electrode Impedances Right at the Headbox – Electrode impedances are checked against a user-selectable threshold and the results are instantly available at the headbox.

Compact System Design – Each system consists of one or more headboxes, weighing in at less than 5 lbs, a system unit and a power unit. System and power units will handle multiple headboxes for high-density recordings.

Up to 256 EEG Channels on a Single Small System Unit – A single system unit will handle up to four head boxes, creating a 256 channel system in about one quarter the space of the original SynAmps unit. Combine two system units to create a super-high density system.

Standard Windows Computer and USB 2.0 Interface – Plug and play operation makes connection and setup easy and fast. No proprietary analog to digital, PCI or data interface cards need to be installed, complicating the system. The industry standard USB 2.0 interface will allow you to move to another PC easily.

Quik-Caps from Neuromedical Supplies Connect Directly – Conversion (EBA) cables are no longer required for cap connection. Neuromedical Supplies Quik-Caps connect directly to the quick-disconnect high-density connector on each headbox for no-problem patient setup. Touch Proof connections for each channel are also provided.

Technical Features

24-Bit Data Conversion – Even within all the excellent high-bit count analog to digital (A/D) converters currently on the market, we”ve specially selected the quietest product available for use in the new SynAmps RT, delivering the best signals with the greatest dynamic range possible. You demand clean, high-resolution data and we deliver it. Data from the SynAmps RT also flows seamlessly through to the new 32-bit version of Scan.

Active Noise Cancellation – Provides unparallel noise immunity. This ensures an accurate representation of the neurophysiological activity even in the most hostile electromagnetic environments

1 G Ohm Input Impedance – The very best in instrumentation amplifier technology is used to ensure that your signals are faithfully recorded.

External (auxiliary) Sensors can be Connected With Ease – Two external inputs per headbox come standard. Both are isolated from patient and computer connections with a+/-5 volt input range. Data is time locked with the EEG data.

External (auxiliary) Sensors Require No External Power – Sensors can be powered from the headbox. up to +/-10V at 100mA. This enables use of strain gauges and a wide range of input devices where the output is time locked to the acquired data.

Bandwidth/Acquisition Rates for the Studies You Want to Run – You want the capability to go from GSR to ABR in one instrument. If you need extra bandwidth and higher acquisition rates, SynAmps RT should be your device of choice. With SynAmps RT, you will never wonder if part of the signal you needed for source or other analysis is above the bandwidth of your data collection device.

Advanced Impedance Technology – Enables the use of advanced impedance modeling techniques and allows you to obtain impedance of the reference electrode in addition to the typical recording channels.
