SIGGI II: Signal Generator & Impedance Meter
EASYCAP SIGGI II is a laboratory tool for checking your amplifier in the event of a possible faulty channel. Most amplifier calibration signals are typically generated inside the software and cannot check fidelity from the electrode input location through to the digitization phase. This device provides an external electrical signal in the voltage range of typical biophysiological signals, which checks the entire analogue signal generated from electrode input through the hardware to the point of transduction and digitization. SIGGI II is a great help for users, resellers, technicians, or developers of devices for the acquisition of biosignals (e.g. EEG amplifiers) who want to be sure that the digitized signals they are seeing are truly representative of the analalogue signal originally acquired.
- Signal Generator: The calibrated Signal Generator, issuing both built-in and recorded signals onto 1-32 channels (accompanied by a trigger signal), can be used to verify an amplifier‘s ability to correctly record amplitudes and frequencies, to visualize filter characteristics, to check linearity of DC amplifiers and to check Common Mode Rejection (CMR).
- Impedance Meter: The Impedance Meter measures the impedance between 1-32 electrodes and their reference and ground electrodes. Special custom adaptors for any EEG-Recording Cap / electrode input box can be supplied. This is a comfortable way to measure impedances independent from the EEG amplifier or if there are reasons to doubt the impedance measurement routines built into the respective amplifier.
- Amplifier / Data Logger: The Amplifier/Data Logger can record, amplify and store user specific signals and replay them with the Signal Generator. The Electrode Tester measures the electrode potential of 1-32 electrodes and its changes for up to 6 hours. This unique tool is indispensable for assessing the suitability of individual electrodes for DC recordings.
