D179 Performance Checker - a versatile performance checker to calibrate EEG/EP and EMG/NCS amplifiers. Accepts output signals from function generators, attenuates the signal, and simultaneously presents it to 32 outputs.

Details

The D179 Performance Checker is a system designed for cases, where the accuracy of your signals on your EEG, EMG, and EP systems needs to be verified. The Performance Checker is created to be used together with either the 3MHz Function Generator (NS-7952) or the TG2511A, depending on the intended use. If you need to check evoked potential and EMG/NCS as well as EEG, you require a signal source with a trigger input, such as the TG2511A digital function generator. If you are more interested in only calibrating your EEG amplifier, you require the NS-7952 3MHz Function Generator.

The D179 Performance Checker accepts the output from the NS-7952 3MHz Function Generator as well as the TG2511A. It attenuates it by 100,000:1 (100dB) and presents it simultaneously to 32 outputs via standard 1.5mm touch-proof sockets on the top of the box. There are in addition a GROUND/COMMON socket and two REFERENCE/NEUTRAL sockets. The system comes together with 32 red, 2 black, and 1 green lead in addition to 1 BNC lead.

The reason for the D179 is due to the Association of Neurophysiological Scientists (ANS, formerly known as EPTA) having transferred the manufacture of their model 1179 Performance Checker to Digitimer Ltd, with which NEUROSPEC AG has been working for the past 20 years. As a result, we are now able to offer the updated 1179A unit (model D179) with or without the required function generator.

Guidelines drawn up by the ANS urge clinical neurophysiology departments to carry out certain routine checks on their equipment to ensure that it is operating within specified standards and that is where the D179 Performance Checker comes in so useful. While many instruments offer internal calibration functions, these checks do not, of course, provide any independent verification that the equipment is functioning correctly. Only by use of an independent external device to carry out EMG amplifier calibration (or EEG amplifier calibration) can such checks be conducted with complete confidence.
