Description

DESCRIPTION

The new D360R 4 Channel Isolated Research Amplifier is intended for electroencephalography (EEG), electromyography (EMG) or evoked potential (EP) studies in a research research environment. Based on the design of our extremely popular 8 channel D360 amplifier, the D360R is a compact, cost-effective, but highly-specified 4 channel equivalent.  The D360R has been designed to meet all of the electrical requirements of IEC 60601-1, including but not limited to (i) full electrical isolation of the input circuit (ii) meeting of or exceeding creepage and clearance minimum requirements (iii) inputs are single fault condition safe.  Unlike the 8 channel D360, the D360R is not a medical device and use is limited to human research applications.

The D360R 4 Channel Isolated Research Amplifier system comprises a main amplifier unit, a remote pre-amplifier headstage with 4 pairs of differential inputs (plus Common) and dedicated Windows-compatible control software.  The control software provides a virtual front panel for the adjustment of settings, including low-pass and high-pass filters as well as amplifier gain. The pre-amplifier headstage is attached to the main amplifier via a fully detachable 2m long cable, which is easily replaced if it becomes damaged during use.

The D360R provides software and hardware de-block capabilities which can be useful to settle the amplifier inputs following electrode placement or re-positioning.  In addition, a TTL controlled de-block function allows a precisely timed external de-block to be applied in situations where a large stimulation artifact might obscure a short latency response.

Analogue signal outputs mean that the D360R is fully compatible with a vast array of commercially available data acquisition systems.  As a result, the user can opt to employ their favoured data acquisition and analysis software. Signal outputs are available on the rear panel via a 9-way “D” connector. The D360R 4 Channel Isolated Research Amplifier is supplied with a “D” to multi-BNC cable for connection to BNC-based data acquisition systems.

The D360R supports system expansion as multiple D360R amplifiers can be connected to a single computer (via several USB sockets or hub) to allow multiples of 4 channels to be controlled through a single software interface.

FAQS

The D360 is certified to the European Medical Device Directive and is suitable for patient use, while the D360R is designed for safe use in human research, but is not a medical device.  The D360 incorporates electrode impedance checking via the control software and headstage LEDs; the D360R does not have any electrode impedance checking mode.  The D360 allows for internal linking of +ve or -ve electrode inputs, so multiple channels can share a single reference electrode.  The D360R operates in standard differential mode with an additional Common input.  The D360 software allows for multiple groups of channels.  The D360R allows channels to be linked and share settings, but does not permit multiple channel grouping.

Yes, the D360R software has been written in order to ensure it is fully compatible with other 64bit software like CED Spike2 and Signal.

Absolutely.  Just like the original D360, the D360R has been designed for full compatibility with TMS and electrical stimulation methodologies, providing a low noise amplifier with excellent common mode characteristics, in order to minimise stimulus artefacts.

We know that headstage cables can receive quite a lot of abuse in a busy laboratory environment and they will on occasions suffer from damage.  For the D360, cable replacement was a costly and time consuming process, as it required the headstage to be returned to Digitimer for rewiring.  With the D360R, we have opted to use a fully removable cable which we will be able to supply replacements for and possibly in a range of lengths.

Yes, multiple D360R’s can be connected to a single host computer to allow for the configuration of systems with greater than 4 channels.  The settings for each amplifier will be vertically arranged in a single instance of the D360R control software.
